Adjust CRF, longest edge, frame rate and audio while retaining the original file
Single video preview, multi-video lists and sequential compression to disk

Is a smaller file guaranteed?

Already optimized videos may get larger. The interface shows the actual size; try stronger compression or smaller dimensions.

Is there a file size limit?

There is no added application limit, but the WASM engine has a limit of about 2 GB and available memory may be more restrictive.

Are all video formats supported?

The FFmpeg engine accepts common MP4, MOV, WebM and MKV files. Some codecs may be unsupported. Output is always MP4.
