Every VPN roundup on the internet will happily rank paid services by speed and price. The free ones are where the honesty usually stops — because a free VPN is the most misleading product in consumer software. The app is free. The servers are not. Somewhere, someone is paying for the bandwidth, the data centres and the developers, and if that someone isn’t you, the most important question about any free VPN is not how fast it is. It is who is paying, and what they are getting for their money.
That is the lens this guide — part of our Cybersecurity & Internet coverage — applies to every free VPN worth mentioning for PC. The conclusion is reassuringly short: there is a small handful of free VPNs run by real companies with a visible business model, and they are genuinely safe to use within clear limits. Then there is a long tail of free VPN apps whose business model is you — your traffic, your data, your machine’s bandwidth — and those are worse than no VPN at all. This guide names the first group, explains the limits honestly, and shows you how to recognise the second group on sight.
The question that matters: who pays for the servers?
A VPN is infrastructure. Routing your traffic through a server in another country costs real money every month, and a popular free app can burn through staggering amounts of bandwidth. Legitimate companies cover that cost in exactly one way: paying subscribers subsidise free users as a form of marketing. The free tier is the shop window; the paid tier is the business. You can verify this model exists because the same companies publish their paid prices, their company address, their privacy policy and, increasingly, independent audits of their no-logs claims.
Illegitimate free VPNs cover the cost in ways that are never on the box. They log your browsing and sell the data to brokers. They inject adverts into the pages you visit. They rent out your connection itself, so strangers’ traffic appears to come from your home IP address — a trick made infamous when it emerged, back in 2015, that the free Hola service was reselling its users’ bandwidth through a sister company, turning millions of PCs into exit nodes for paying customers. And the mildest versions simply harvest your email address and attention for aggressive upselling of things you don’t need.
This is why “the business model is the review” is not a slogan but a method. For a free VPN, ask one question — how does this company make money? — and you have usually finished the review. If the answer is “a paid tier from a named company with a published policy”, keep reading. If the answer is unclear, the honest assumption is that your data is the revenue. The EFF’s guidance on choosing a VPN makes the same point from first principles: a VPN shifts trust from your internet provider to the VPN company, so a provider you cannot evaluate is a provider you should not trust.
The trustworthy free VPNs at a glance
| Service | Data limit | Free locations | Devices | The honest catch |
|---|---|---|---|---|
| Proton VPN Free | No data cap | A small handful of countries | 1 device | Few locations, one connection, speeds ease off at busy times |
| Windscribe Free | Around 10 GB per month | Around 10 locations | Generous device allowance | The monthly meter runs out fast with video |
| PrivadoVPN Free | Around 10 GB per month at full speed | A small set of cities | Limited connections | After the allowance, speed drops sharply |
| Almost any other “free VPN” app | “Unlimited everything!” | Claims dozens | Varies | No visible business model — you are the product |
Three names survive scrutiny, and that brevity is the finding. Everything below explains what each one gives you, what each one keeps for its paying customers, and where the boundaries of safe free VPN use actually lie.
Proton VPN Free: the one genuinely honest free VPN
If you install one free VPN after reading this page, make it Proton VPN Free — it is the only free tier we can recommend without a data-cap asterisk. There is no monthly allowance: you can leave it connected all day, every day, and it will keep working. There are no adverts in the app. The company behind it is Proton, the Swiss firm better known for Proton Mail, and the model is the straightforward one described above: free users are the top of a funnel that converts some of them into paying customers, and Proton says so openly.
The supporting evidence is unusually strong for a free product. The apps are open source, so outside experts can inspect the code. The no-logs policy has been put through independent audits. The company is based in Switzerland, outside the main intelligence-sharing blocs, and the free tier applies the same no-logs stance as the paid one — Proton doesn’t run a “free users get logged” second class, which is precisely the detail that matters most.
Now the limits, because they are real. The free tier connects one device at a time, which on a PC-focused guide is acceptable but rules out covering your phone simultaneously. Free servers exist in only a small handful of countries — the exact set changes over time — so you cannot reliably appear in a specific country, and free servers are not intended for streaming or heavy downloading; file-sharing traffic in particular is a paid-tier affair. Speeds are respectable rather than maximal, and at peak hours on popular free servers you will feel the difference. Think of it as a well-built public road rather than a private motorway: open to all, honestly maintained, and not the fastest route at rush hour.
Verdict: the default recommendation. For securing café Wi-Fi, keeping your ISP out of your browsing habits and everyday privacy hygiene, Proton VPN Free is — uniquely at this price — the full product with smaller geography.
Windscribe Free: generous, if you can live with the meter
Windscribe takes the opposite approach: a proper spread of server locations and a friendly app, rationed by a monthly data allowance of around 10 GB if you register with an email address (less if you don’t). Within that allowance it is a capable service — a Canadian company with a published no-logs position, apps for every platform, and a genuinely useful built-in blocker (called R.O.B.E.R.T.) that strips many adverts and trackers at the network level, a bonus most VPNs at any price don’t include.
Ten gigabytes sounds like a lot until you price real activities against it. Web browsing, email, messaging and maps for a month? Comfortable. A few hours of HD video? That can be most of the allowance in an evening. So Windscribe’s free tier is best understood as a utility VPN: switch it on for the café, the airport, the hotel and the untrusted network, switch it off at home, and the meter lasts the month. Used that way, it is arguably better than Proton for travellers, because the location list is wider. Used as an always-on connection, you will meet the limit around the middle of the month, every month.
Verdict: the best capped free VPN for occasional use on untrusted networks. The meter is honest, the company is real, and the blocker is a genuine extra — just don’t plan your streaming around it.
PrivadoVPN Free: full speed until the allowance runs out
PrivadoVPN’s free tier is built around a simple shape: roughly 10 GB a month at the service’s full speed, from a small set of server cities, with the connection slowing right down once the allowance is used rather than cutting off entirely. That “throttled, not dead” detail makes it more forgiving than a hard cap — an email will still send at the end of the month, even if nothing streams.
The trade-offs sit where you’d expect. The free location list is short, simultaneous connections are limited, and Privado is a younger, smaller name than Proton or Windscribe, so its public track record and audit history are thinner. The service presents a clear no-logs policy and the paid tier is conventionally priced, which keeps it on the right side of the business-model test — but with less evidence behind it than our headline pick.
Verdict: a reasonable second choice, especially if you value speed in short bursts. Choose Proton for trust and unlimited data, Windscribe for locations, Privado for pace — or accept that wanting all three at once is the sound of the paid tier calling.
What free tiers take away: data, servers, speed, devices
Free tiers differ in which dial they turn down, but the dials are always the same four. Understanding them lets you read any free VPN offer — including the ones that launch next year — without needing a review.
Data. The commonest limit. Capped plans in the region of 10 GB a month are typical of the honest end of the market; treat “unlimited free VPN” claims from unknown brands as a warning rather than a feature, because unlimited bandwidth is the most expensive thing to give away.
Servers and locations. Free users get a subset: fewer countries, fewer cities, and the busiest servers, shared with every other free user. This matters for two practical reasons — a specific country may simply not be available, and congestion follows the crowd.
Speed. Even “full-speed” free plans slow down in practice because of that congestion, and some quietly deprioritise free traffic. Any VPN costs you some speed; our guide to how to improve internet speed explains how to measure the difference properly rather than guessing.
Devices. One simultaneous connection is common on free tiers. If your household’s definition of “the PC” includes a second laptop, a phone and a tablet, a free plan covers a fraction of it.
Support and polish. The dial nobody mentions until something breaks. Free users typically get help-centre articles and community forums rather than direct support, and free apps are where providers test new interfaces first. None of this is disqualifying — the trustworthy three above are all polished products — but if a connection problem at a critical moment would cost you more than a subscription, that arithmetic belongs in the decision.
None of these limits are scams — they are how an honest free tier stays honest. The scam is the free VPN with no limits and no visible way of paying for them.
The danger list: free VPNs that cost more than money
Set against three trustworthy names is an app-store long tail of free VPNs from companies you cannot identify, with privacy policies that dissolve under reading, and promises — unlimited, fastest, military-grade, forever free — that cost real money to keep. The documented failure modes are not hypothetical:
- Logging and resale. A free VPN sees everything your ISP used to see. Providers with no other revenue have sold exactly that visibility. A widely cited study by Australia’s CSIRO research agency examined hundreds of VPN apps and found a large share carried third-party tracking libraries — in a product people install specifically to avoid tracking.
- Resold bandwidth. The Hola affair remains the template: free users’ connections were quietly used as exit points for other people’s traffic. If someone else’s browsing appears to come from your IP address, their problems become your problems.
- Ad injection and worse. Some free apps have injected advertising into web pages, and security researchers periodically find outright malware wearing a VPN’s clothes — which is why an unknown free VPN fails the most basic test in our wider guide to how to protect your online privacy: never hand your traffic to a stranger to escape being watched.
- Permission creep. A VPN app needs to manage network connections. It does not need your contacts, your precise location or your photo library. Excessive permissions on a free VPN are the business model showing through the wallpaper.
Practical defences are simple. Only install VPNs from companies you can name, with a website, a paid tier and a privacy policy that says plainly what is logged (ideally: nothing meaningful) and for how long. Prefer providers whose claims have been independently audited. And treat store reviews as near-worthless — five-star ratings are the cheapest thing in this industry.
Browser “VPN” extensions are (mostly) not VPNs
A special warning belongs to the hundreds of free “VPN” add-ons in the Chrome and Edge extension stores, because many of them are not VPNs at all. They are proxies: they route your browser’s traffic through a remote server, changing the address websites see, but they do not create the encrypted, system-wide tunnel a real VPN app provides. Everything outside the browser — your mail app, your games, your other browsers — travels outside the tunnel entirely. Some proxy extensions encrypt the browser leg properly; many historically did not, and the category has repeatedly hosted extensions that harvested browsing histories wholesale.
Proxies have a legitimate narrow use — making a website think you are somewhere else — and if that is all you need, a reputable provider’s extension (Proton and Windscribe both offer them as companions to their real apps) is a reasonable tool. But install them knowing what they are: a browser-level redirect, not protection, and never a substitute for the PC app on an untrusted network.
Setting up a free VPN on your PC — properly
Whichever of the three you choose, the setup habits matter as much as the choice itself, because a badly configured VPN fails silently. Download the app only from the provider’s own website — never from a download portal or a lookalike store listing, which is how fake versions circulate. Install it, create the free account the tier requires, and before connecting, open the settings and change three things.
First, the kill switch: this blocks all traffic if the VPN connection drops, so a momentary disconnect doesn’t expose your real connection mid-session. On trustworthy free tiers it is available and off or on by default depending on the app — find it and enable it. Second, auto-connect: set the app to connect automatically, ideally whenever the PC joins a network it doesn’t recognise. This is the setting that turns “I meant to switch it on at the airport” into actual protection. Third, the protocol: modern apps choose automatically between protocols such as WireGuard and OpenVPN, and automatic is the right answer for almost everyone — the modern options are both faster and better audited than the legacy settings still listed for compatibility.
Then verify the tunnel is doing what you think it is. With the VPN off, note your IP address on any “what is my IP” page; connect to the VPN and check it has changed to the server’s location. Run a DNS leak test — free ones are one search away — and confirm your requests are resolving through the VPN rather than leaking to your ISP’s servers. Two minutes of checking beats a month of assuming, and if a free app fails either test, that is your review of it: uninstall and move to the next name on the shortlist.
When free is genuinely enough — and when it isn’t
Free is enough, honestly, for a recognisable set of jobs. Securing your connection on café, airport and hotel Wi-Fi a few times a month: yes, and this is the classic case — Proton Free does it without even watching a meter. Keeping your ISP from building a browsing profile, for ordinary home use: yes, again mainly via Proton. Occasional access to a site that behaves differently by region, where the free server list cooperates: usually. Trying the whole VPN idea before spending anything: emphatically yes — a month on a trustworthy free tier teaches you more than any review.
Free is not enough when the job is continuous or specific. Streaming is the commonest failure: free tiers rarely support it officially, rarely offer the countries people want, and capped plans burn a film’s worth of data before the interval. Torrenting is generally a paid-tier activity on reputable services. Covering a whole household’s devices, appearing in one particular country reliably, or getting top speeds for gaming and large downloads — all paid territory. And if your reason for a VPN is serious — journalism, activism, genuine personal risk — a free tier was never the right tool; you need a paid provider chosen on evidence, which is what our roundup of the best VPN services is for.
One middle case deserves naming: working from home on your own broadband. A free VPN will encrypt your traffic to your employer’s systems only if the employer’s setup works that way — most companies issue their own VPN for work traffic, and layering a personal free VPN underneath usually adds nothing but a slower connection and a confused IT department. Keep the free VPN for your personal browsing and the untrusted networks away from home; leave the work tunnel to work.
Frequently asked questions
Is any free VPN actually safe? Yes — a few. Safety comes from the business model, not the price: Proton VPN Free is funded by its paid subscribers, publishes a no-logs policy that has been independently audited, and shows you no adverts. Free VPNs from unidentifiable companies offering unlimited everything are the unsafe kind, because your data is the only revenue available to them.
Why does Proton offer unlimited free data when rivals cap it? Because its free tier is deliberately a sample of the paid one with the geography removed: same apps and privacy stance, far fewer server locations and one device. Data costs it less than server capacity in many places does, and the free tier exists to convert users into subscribers over time — a model it states openly.
Can I watch Netflix or other streaming services with a free VPN? Realistically, no. Free tiers don’t guarantee streaming access, the server countries are few, and on capped plans a single film can consume much of your month. If streaming from other regions is your main goal, that is a paid-VPN use case.
Will a free VPN slow my PC down? Somewhat — every VPN costs a little speed, and free servers add congestion on top. On a decent connection, Proton or Windscribe are fine for browsing and calls; expect noticeable drops at peak times on the most popular free locations, and don’t judge the concept by a free server at its busiest hour.
Are free VPN browser extensions safe to use? Most are proxies rather than true VPNs, they only cover browser traffic, and the category has a poor history on data collection. Stick to extensions published by a reputable VPN company whose full app you could also install, and don’t mistake an extension for protection on public Wi-Fi.
Should I just pay for a VPN instead? If you want streaming, many countries, several devices, top speeds or support, yes — the honest free tiers are samplers and safety nets, not full services. Paying a few pounds or dollars a month to a well-evidenced provider buys all four dials turned up at once.
Can I use a free VPN for torrenting? On the trustworthy free tiers, effectively no — peer-to-peer traffic is typically blocked or unsupported on free servers, both for cost and legal-exposure reasons. It is one of the clearest dividing lines between free and paid, and it is deliberate rather than a bug.
Do free VPNs work in countries that restrict VPN use? Unreliably. Beating determined network censorship needs obfuscation features and constant cat-and-mouse updates, which providers reserve for paying customers — and free servers are the first to be identified and blocked. If you are travelling somewhere VPNs are restricted, set up a reputable paid service before you leave rather than depending on a free tier on arrival.
The bottom line
“Best free VPN for PC” has a shorter honest answer than the app stores suggest. Install Proton VPN Free if you want one safe, unlimited, no-asterisk answer. Choose Windscribe Free if wider locations matter more and your use is occasional enough to live within roughly 10 GB a month, and keep PrivadoVPN Free in mind for full-speed short bursts. Everything beyond those three should have to prove its business model to you before it earns a place on your PC — and almost none of it can. A free VPN from a company that makes money from subscribers is a sample. A free VPN from a company that makes money from you is a surveillance product with better marketing. The difference is the whole review.
