FAQ
Is it really free?
Yes — every tool on this site is 100% free with no limits, no signup and no watermarks.
Is my data private?
Absolutely. All processing happens locally in your browser. Your files are never uploaded to any server.
Why is the result an MP4 file?
The browser re-encodes your video as MP4, which is much smaller than most camera files. MP4 plays everywhere — Chrome, Firefox, Edge, Safari and on YouTube.
How small will my video get?
It depends on the original. A phone video can shrink by 50–80% at 480p. Very long videos take a while — keep the tab open until it finishes.
Complete Guide to Compressing Videos
Phone videos are huge: a few minutes can be hundreds of megabytes, too big to send or upload quickly. Compression shrinks the file by lowering the bitrate — the amount of data per second. A 720p target keeps most detail for sharing, 480p is a good balance, and 360p is smallest for messaging. This tool re-encodes your video in the browser at the quality you pick and downloads an MP4 file. The original stays untouched on your device. For very long videos, split them first or compress in parts.
