Compress video to a specific size
Pick a target file size and we'll shrink any video to fit. Perfect for upload limits — Outschool (50MB), Discord (25MB), email attachments, and more.

How it works. The encoder calculates the bitrate needed to hit your target, then
does a two-pass encode for accuracy. Resolution and framerate scale down automatically when
the target is small.
How it works
-
1
Drop your video. Anything ffmpeg can read works — MP4, MOV, MKV, WebM, AVI, and more.
-
2
Pick a target size. The encoder computes the bitrate that hits that size, with a safety margin so the file lands at or just under your target.
-
3
Two-pass encode. Two-pass H.264 distributes bits where the video needs them, so quality stays as high as possible at the chosen size.

4
Download. Output is a streaming-ready MP4 (moov atom up front). Files auto-delete after one hour.
Why these presets?
- 10 MB — small enough for most chat apps and Slack free tier.
- 25 MB — Discord free upload cap.
- 50 MB — Outschool video upload cap. Also fits most email providers.
- 100 MB — large enough for higher quality short clips.
- 250 MB — when you want minimal quality loss on a multi-minute clip.
