The core difference: upload vs. direct
WeTransfer and similar services work by uploading your file to their cloud, holding it, and giving the recipient a download link. It’s convenient because the recipient can grab it later — but your file lives on someone else’s server for the duration, under their retention and their risk.
Pairchute is built the other way around: the file streams directly between the two browsers, encrypted end to end, and is never stored anywhere. The trade is that both people are online for the transfer. If you want nothing left on a server, that trade is the point.
What upload services do better
A stored copy is genuinely useful, and pretending otherwise would be dishonest. Because an upload service holds the file, the recipient can collect it whenever they get round to it — tonight, tomorrow, from a different device. The link survives you closing your laptop. One link can serve twenty people. You can paste it into a document and it keeps working.
Pairchute can do none of that, and not by omission: with no server there is nowhere for a file to wait. Both people are present or nothing moves. If the person you are sending to is asleep in another timezone, an upload service is the right answer and this one is not.
Upload-based and direct are two different products
It is tempting to read direct transfer as a better version of upload transfer. It is not — the two optimise for opposite things. Upload-based tools optimise for the file being available to someone later, and accept that a copy has to exist somewhere in the meantime. Direct tools optimise for no copy existing anywhere, and accept that both parties have to show up at the same moment.
Neither constraint is a bug. Choose by which property you actually need for this file: waiting, or not being stored. That question has a clear answer far more often than "which is better" does.
What "no size limit" actually means here
It means the limit is your hardware rather than a plan tier. Received data is streamed to disk as it arrives instead of being assembled in memory first, so a 200 GB file needs 200 GB of free drive space and no particular amount of RAM. Nothing is being staged on a server, so there is no per-file cap for anyone to raise.
Two honest qualifications. Disk streaming uses the File System Access API, enabled in Chrome and Edge; a receiving browser without it falls back to memory and is capped at 512 MB. And a transfer runs in one sitting — if the connection drops, the partial file is discarded and that file starts again from zero.
When Pairchute is the better fit
Choose Pairchute when the file is sensitive, when it is too big for an upload cap, or when you simply do not want a copy sitting on a company’s servers. Choose a traditional upload service when the recipient cannot be online at the same time and you need the file to wait for them. For a direct, private, one-sitting transfer with nothing left behind, Pairchute is purpose-built.
How they compare
Both send big files in a few clicks, so the difference is not in the first minute of use — it is in where the file goes and what is left afterwards. Read the table below as the consequences of one architectural choice rather than a feature scorecard: everything in the right-hand column follows from there being no server, and everything in the left-hand column follows from there being one.
| Typical upload tool | Pairchute | |
|---|---|---|
| Where your file goes | Uploaded to their cloud | Straight browser → browser |
| Stored on a server | Yes, for days | Never |
| Account / email | Often required | None |
| Size limit | Capped by plan | Bounded by your disk |
| Both online at once | No | Yes (no server to hold it) |
| Encryption | At rest on their servers | End-to-end between you two |
