Video Compressor

Quality sets how much detail is kept: move it toward Smaller file for a lighter file, or toward Better picture for a cleaner one. Resolution scales the video down to 1080p, 720p or 480p, and frame rate can drop to 30 or 24 fps. Audio can be set to 128 or 96 kbps, removed, or left at Original, which copies the soundtrack as it is when an MP4 can hold it and otherwise converts it at 192 kbps. Custom starts at the same settings as Balanced.

Lowering the resolution, for example from 1080p to 720p, and moving the quality slider toward Smaller file save the most. A lower frame rate helps most with 60 fps footage. Removing the audio saves a little.

CRF is the quality number the H.264 encoder works to. Lower numbers keep more detail and make bigger files. Balanced uses 28, Smaller file 32 and Smallest file 35, and the Custom slider goes from 18 to 38.

No. Resolution and frame rate only ever go down. A 720p video stays 720p if you pick 1080p, and a 24 fps video stays at 24 fps if you pick 30.

Yes. It is completely free, with no account and no limit on how many files you process. Downloads carry no watermark.

No. The tool runs inside your browser using WebAssembly. Your file is read into memory on your device, processed there, and the result is saved straight to your downloads.

You can start with MP4, MOV, WebM, M4V files. The result is saved as MP4.

There is no fixed limit, but the file has to fit in your browser's memory. Files up to a few hundred megabytes work well on most computers. For very large files, use a desktop browser such as Chrome, Edge or Firefox.

Yes, on modern iPhone and Android browsers. Processing is slower on a phone than on a computer, so shorter files work best there.
