Your video stays on your computer
Most online video tools upload your file to their server. This one doesn't need to.
Nothing is uploaded
The page uses the video tools built into your browser. Once it has loaded, it even works offline.
No waiting in a queue
No upload and no download of the result means even a long screen recording is done as fast as your computer allows.
No limits
No sign-up, no watermark and no daily cap. Use it on as many files as you like.
Questions, answered
Is this video compressor free?expand_more
Yes. There is no sign-up, no watermark and no limit on the number of files.
Is my video uploaded to a server?expand_more
No. It all runs inside your browser, on your computer. The file is never sent anywhere, and the page keeps working if you go offline after it has loaded. Read the privacy policy for details.
How much smaller will my video be?expand_more
It depends on the video. Phone videos and screen recordings often shrink a lot, because they are saved with a lot of detail per second. The page shows the exact saving when it’s done, and tells you if the file didn’t get smaller.
Which size should I pick?expand_more
720p for most uses: it looks sharp on laptops and phones. 480p for email and chat apps with small upload limits. 1080p if small text or fine detail must stay crisp.
What format is the compressed video?expand_more
MP4 with H.264 video and AAC sound, which plays on almost every phone, computer and website.
Can I make it even smaller?expand_more
Pick a smaller size, switch off “Keep the sound” if you don’t need it, or cut the video shorter first with the trim tool.
Is there a file size limit?expand_more
There is no fixed limit. The finished MP4 is held in your computer's memory until you download it, so files of a few gigabytes may fail on computers with little memory.
Which browsers does it work in?expand_more
Recent versions of Chrome, Edge, Opera and Safari, and Firefox 130 or newer. It uses the browser's built-in video tools (WebCodecs).
