We do everything we can to make sure our service is optimized for speed, so that you can upload your transfers quicker than Sonic the Hedgehog gets through chilli dogs.
This means that if you're experiencing a slow upload, it most likely has something to do with your Internet service provider (ISP), network connection or something blocking our connection from performing correctly.
There are some things that you can do to ensure you are getting the fastest speed possible:
First thing’s first, and as obvious as it is: have you tried the “turn it off and back on again” trick? Restarting your browser, computer, and router can often work wonders and will solve your upload issue quicker than anything else on this list.
It’s very possible that one or more of your browser extensions or add-ons could be causing some slowness, especially if you’re using an ad blocker or a script blocker. To test this out, please re-try the upload in your browser’s Incognito or Private browsing mode, or after disabling all of your installed extensions.
Check your upload speed. You can run a speed test on websites such as speedtest.net. We’d recommend that you have an upload speed of at least 5Mbps to use WeTransfer comfortably and without any interruptions.
Are you using any antivirus or firewall software? If so, then you should temporarily disable it and re-try another upload. Make sure you re-enable it right after, though!
If your files are on an external hard drive, USB stick, or cloud folder, it helps to move them to your local drive before uploading. Make sure they’re not being opened or used by another app or programme running in the background, too.
If you're using our service on a corporate network, you can check with your system administrator to see if there are any limitations for using our service in your workplace. If necessary, ask them to contact us directly for technical support.
If all else fails and you are desperately trying to send your transfer in time (pesky deadlines!), you could also try your transfer on another browser, or via another network like a 4/5G connection on a mobile device. If this succeeds, this would suggest your browser's current settings are interfering with our connection.
Of course, if you need any further help, contact our Support team, and we’ll do our best to get you back on track. They’d love you forever and a day if you could attach a screenshot of the speed test result you got after going through with step number 3 above.
