The reasons may vary:
Server load — during peak hours, upload speed decreases due to a large number of users.
Routing to WeTransfer servers — even with fast local internet, the path to data centers may be slow.
Browser or extensions — ad blockers, VPNs, and outdated browser versions can slow down data transfer.
File format and size — compressing and preparing large files takes extra time on the service side.
What to do: upload files during off-peak hours (morning or late evening), use a wired connection, disable VPN and unnecessary extensions, try another browser, or use the WeTransfer Desktop app, which works more reliably with large files.
❗ If WeTransfer constantly uploads slowly while your internet speed is high and stable — 👉 report this on Xolvie 👈 so the company can check routing and server load.
