About Video to MP4
What this tool does
Video tools convert between formats (MP4, WebM, GIF), trim clips to a specific time range, compress video for sharing, and extract frames or audio. Processing uses FFmpeg compiled to WebAssembly, so everything stays in your browser.
Why use this tool
Uploading raw video to an online converter exposes your content and takes bandwidth. With client-side processing, you keep full control of your footage while getting quick format conversions and basic edits done without desktop software.
How it works
The tool loads FFmpeg.wasm into memory, reads your video file, and executes the requested pipeline: re-encoding to a target codec, cutting at specified timestamps, or reducing resolution and bitrate. Output is written to a virtual file system and offered for download.
Pro tip
H.264 inside an MP4 container is the most universally supported combination. For web-only playback, VP9 in WebM gives better compression at the same quality.
