Processed locally in your browser. Files never leave your device. Up to 1GB — larger files go to the desktop app.

What X actually accepts

X allows up to 2 minutes 20 seconds and 512MB, but a 512MB file is slow to post and often fails on mobile. 50MB is the size that usually publishes on the first try.

Use H.264 MP4. WebM and HEVC-only files still fail in a lot of clients. This preset converts while it compresses.

If the clip is longer than 2:20, trim it on this page first. X will reject the extra seconds even if the file is small.
