Video shrinker

Mastodon won't take videos over 99 MB. Drop one here and it'll be shrunk to fit — on your device, without uploading anything.

This browser can't do it

Try Chrome, Edge, or Safari 16.4+. On a desktop you can also use HandBrake, or ffmpeg:

ffmpeg -i in.mov -c:v libx264 -preset slow -crf 26 \
  -vf "scale='min(1920,iw)':-2" -c:a aac -b:a 128k \
  -movflags +faststart out.mp4

Reading video…

This one's already fine

No point re-encoding it — upload it to Mastodon as it is.
