How do I convert a video to MP4?

Upload your video, select MP4 as the output format, choose your preferred quality, and click Process. The conversion runs entirely in your browser using FFmpeg WebAssembly — nothing is uploaded to a server.

What video formats and codecs are supported?

Input supports virtually any format the browser can read, including MP4, MKV, MOV, AVI, WebM, and OGG. Output formats include MP4 (H.264), MKV, MOV, AVI, and OGG. Common codecs like H.264, H.265, VP8, and VP9 are handled automatically.

Can I convert a video without losing quality?

Use the High quality preset to preserve as much detail as possible. For lossless container changes (e.g. MKV to MP4 with the same codec), the tool re-encodes at a high bitrate to minimize quality loss.

Is there a file size limit?

You can process files up to 2 GB. Since everything runs in your browser, speed depends on your device — desktop machines handle large files fastest.
