Zip it, email it, watch it bounce. Or hand over one link.
Yesterday's version: you zip a folder of 4K clips, attach it to an email, and Gmail rejects it the second the file passes 25MB. Today's version: you drag the same folder onto a web page, wait for the bar to fill, and paste one link into a message. That link is the whole trick. Any file too big to email goes up to a free transfer service, and the person on the other end downloads it from a URL instead of an inbox. The free caps are generous now, up to 50GB per transfer on some services with no account at all, so the real question isn't whether you can send a big file for nothing. It's which tool fits how big, how often, and how private.
What each free service gives you before it asks for money.
Free tiers moved around a lot in the last year, WeTransfer most of all. Here's where the well-known ones sit right now. Verify the number on the service's own page before a big send, because these shift.
| Service | Free per transfer | Link expires | Account to send |
|---|---|---|---|
| SwissTransfer | Up to 50 GB | Up to 30 days | No |
| Filemail | Up to 5 GB | 7 days | No |
| TransferNow | Up to 5 GB | 7 days | No (optional) |
| WeTransfer | About 3 GB, metered monthly | 3 days | No (email verify) |
| Smash | 2 GB (bigger files may queue) | 7 days | No |
| Dropbox Transfer | Up to 2 GB on Basic | Varies | Yes |
| Google Drive | 15 GB shared storage | No auto-expiry | Yes (both sides ideally) |
Two things are worth reading off that table. First, the biggest free single-transfer allowance right now sits with SwissTransfer, which is genuinely free with no paid tier at all and keeps files around for up to a month. If you have one giant thing to get to one person and you're never doing it again, that's hard to beat. Second, Google Drive and Dropbox aren't really transfer tools, they're storage you can share out of. That distinction matters more than it looks, and it's the next section.
Sending a file and parking a file are different jobs.
A transfer service is built for one-time delivery. You upload, you get a link, the link dies after a few days, and the file is gone. That's a feature, not a flaw: you don't want a client's 8GB video sitting on a stranger's server forever. Cloud storage like Google Drive or Dropbox is the opposite. The file lives there until you delete it, and "sending" it means sharing a folder or a link out of your own drive. Great when the recipient already lives in the same ecosystem, clumsier when they don't, because sharing permissions, "request access" emails, and Google accounts all get in the way fast.
The email route is the one to stop reaching for. Gmail caps attachments at 25MB and will quietly offer to stick anything bigger in Drive instead. Outlook sits around 20MB. Those limits haven't moved in years and they aren't going to, so a multi-gigabyte send over email attachment simply isn't a thing. When someone asks you to "just email it," what they actually want is a link. They just don't know it yet.
How to send a large file free, start to finish.
It works the same across almost every transfer service, so the muscle memory carries over even if you switch tools next month.
- Match the tool to the size. Under 2GB and any of them work. Between 2 and 5GB, reach for Filemail or TransferNow. Past that, SwissTransfer's 50GB free tier is the one that won't make you pay. Check the current cap on the service's own page first; free limits are the fastest-moving number in this whole space.
- Zip a folder of many small files first. One 4GB archive uploads cleaner than four hundred loose photos, and the recipient gets a single tidy download instead of a mess. Skip this for a single large video, which is already one file.
- Drag the files onto the page and let it upload. Don't close the tab. A browser upload is live only for as long as the bar is moving, and killing the tab kills the transfer. A wired connection beats flaky wifi for anything over a couple of gigs.
- Pick link or email delivery. A link you copy and paste yourself works everywhere, including Slack, WhatsApp, and a text message. Email delivery from the service is convenient but occasionally lands in spam, so a link you send through your own channel is the safer default.
- Add a password and a sensible expiry if it's private. Client contracts, anything with personal data, anything you'd hate to see leaked: set a password and the shortest expiry that still gives them time to grab it. Then tell them the expiry so the file doesn't vanish before they download it.
A shared link is the actual product here. Everything else is just how big a file you can hang off it for free.
Still free, still fine, but read what changed.
WeTransfer is the name most people reach for, and it still works. Two changes are worth knowing before you lean on it. Its free plan moved from a straightforward 2GB-per-transfer model to a metered one: roughly 3GB and a capped number of transfers per month, which stings if you send often rather than once in a blue moon. And in mid-2025 the company updated its terms of service with broad language that appeared to grant it a license to use uploaded files to improve machine learning models. The creative community, whose work runs through WeTransfer constantly, pushed back hard. WeTransfer walked the wording back within days and clarified that it doesn't use uploaded content to train AI. The episode is a fair reminder to skim the terms of any service you pipe client work through, not a reason to single WeTransfer out forever; the fix shipped and the walk-back was clear. If the monthly cap is your problem, SwissTransfer or TransferNow give you more headroom for free.
When you're the one always collecting files.
Everything above is built for sending: one file, out the door, link expires. Flip it around and a different problem shows up. If people keep sending files to you, a chain of expiring links is the wrong shape.
Picture a photographer gathering raw shots from a second shooter every weekend, a small studio taking 3GB deliverables off clients on repeat, or anyone running an "upload your files here" form on a website. A one-off transfer link doesn't fit any of that. You'd be handing out a fresh WeTransfer address every time, racing to download before links expire, and re-sorting everything into a folder by hand. What you actually want is a single place people upload to, once, that keeps working and drops every file into one spot you control.
A transfer link
WeTransfer, SwissTransfer, and the rest.
- ✓ Perfect for a one-time send, zero setup, drag and go
- ✓ Big free caps, no account for you or the recipient
- × Expires in days, so it's the wrong tool for collecting on repeat
- × A new link every time, and organizing what lands is on you
A drop page you own
Tonta, set up once and handed out as a link.
- ✓ One persistent link people upload to, no account needed on their end
- ✓ Every file lands in one folder in your dashboard, not scattered across expiring links
- ✓ 5GB free tier, no card, and images get resized and optimized on the way in
- × A few minutes of setup, and it's for receiving files, not one-off sending
To be plain about the tradeoff: Tonta is upload infrastructure, so setting up a drop page means dropping a small script tag on a page or spinning one up in the dashboard, a notch more involved than typing wetransfer.com into a browser. If you send one big file once, don't bother, use the transfer services above. But if collecting files is a recurring part of what you do, a drop page you own beats re-issuing expiring links forever, and the free tier covers a single collection point at 5GB before you pay anything. It's the honest answer to the receiving side of this problem, not the sending side.
What's the largest file I can send for free?
Right now the biggest free single-transfer allowance with no account comes from SwissTransfer, at up to 50GB per transfer, kept for up to 30 days. Filemail and TransferNow sit lower at around 5GB free. Always confirm the current number on the service's own page, because free caps in this space change often.
How do I send a large file through email?
You don't, past about 25MB. Gmail caps attachments at 25MB and Outlook around 20MB, and those limits haven't budged in years. For anything bigger, upload the file to a transfer service, copy the download link, and paste that link into your email instead of attaching the file. Gmail will even offer to do a version of this for you by dropping large attachments into Google Drive.
Is WeTransfer still free, and is it safe?
Yes, WeTransfer still has a free plan, though it's now metered to roughly 3GB and a limited number of transfers per month. Files are encrypted in transit. In 2025 it drew criticism for terms of service wording that looked like it permitted using uploads to train AI models; the company revised the language within days and stated it doesn't do that. If you want a bigger free cap, SwissTransfer and TransferNow give you more room.
How do I send large files without creating an account?
SwissTransfer, Filemail, and TransferNow all let you send without signing up, though some ask you to verify an email address. Drag your files onto the page, choose whether to get a link or have the service email the recipient, and send. No account, no install.
Are free file transfer services actually secure?
Most encrypt files in transit, and several go further: Internxt Send and SwissTransfer offer end-to-end encryption, and many services let you password-protect a transfer and set a short expiry. For anything sensitive, always set a password, pick the shortest expiry that still gives the recipient time, and check the service's own privacy terms before uploading client or personal data.
What if people need to send large files to me, over and over?
Then a one-off transfer link is the wrong shape, because it expires and you'd be re-issuing it constantly. A drop page, a single upload link you set up once and hand out, keeps working and collects every file into one folder you control. That's the job Tonta is built for, with a 5GB free tier and no account needed for the people uploading to you.
For one big send, grab a transfer link.
For the other direction, when files keep coming to you, set up a drop page once and stop chasing expiring links. The free tier needs no card.
