Compress video
Make any video small enough to send. It runs in your browser, so nothing is uploaded and there's no size limit.
Drop a video, or choose a file
MP4, MOV, WebM or MKV. Any size.
Your file never leaves your device
How it works
Your browser's built in video encoder rebuilds the video at a lower bitrate. Okaysize works out the bitrate from your target size and the video's length, keeps the audio clear and checks the finished file before you download it. If it would come out over the target, it runs again a little lower.
What gets kept
Resolution, frame rate, rotation and audio sync are kept unless you change them in Advanced. Location and device details stored in phone videos are removed by default.
When compression won't help
Some videos are already compressed about as far as they can go. If the result would be about the same size as the original, Okaysize tells you and offers the original back instead of a worse copy.
Ready made presets
Each one is set to a platform's current limits, checked against its official help pages.

Questions
- Is there a file size limit?
- No. The only limit is your device's memory. Okaysize estimates that before it starts and tells you if a file is likely too big for this device.
- Does my video get uploaded?
- No. The video is processed on your device. You can check by opening your browser's network panel while it runs: no file data is sent.
- Which formats work?
- MP4, MOV, WebM and MKV work in all modern browsers. The output is an MP4 with H.264 video and AAC audio, which plays almost everywhere.
- Will it look worse?
- Smaller files always lose some detail. Short clips look close to the original. For long videos at small sizes, lowering the resolution in Advanced often looks better than squeezing the bitrate.
