Here are some useful and up-to-date recommendations:
If file uploads in WeTransfer stop or freeze, the reasons are most often related to your connection or browser.
Check your internet speed (especially the upload speed), disable VPN and ad blockers, and clear your browser cache.
It’s best to use the latest version of Chrome, Firefox, or Edge. For large files, temporarily disable your computer’s sleep mode, since any interruption of the connection breaks the upload.
Also, make sure the file doesn’t exceed your plan’s limit and doesn’t contain prohibited formats.
If the problem persists, try uploading via mobile internet or use the WeTransfer Desktop app, which handles large files more reliably.
❗ If WeTransfer freezes during upload even with a stable internet connection and support doesn’t provide a solution — 👉 describe the situation on Xolvie 👈 to draw attention to the problem.
