How to use Video Converter

1 Drop your file in the box above, or pick one of the tools below.
2 Each tool runs entirely in your browser — files never leave your device.
3 Adjust the tool-specific options if shown, then click the action button.
4 Download the converted file when it's ready.

Video formats are really containers — MP4, WebM and MOV each wrap video and audio differently, and the wrong one simply will not play on a given phone, editor or website. Converting between them used to mean a desktop install or uploading a huge file and waiting. Our free video converters do it right in the browser using FFmpeg compiled to WebAssembly, so even large clips are re-packaged on your own device with no upload. MP4 is the safest choice for sharing and playback everywhere; WebM is leaner for the web; MOV is common straight out of Apple devices. Pick your target, convert, and download — no signup, no size paywall up to the on-page limit.

Frequently asked questions

Are my videos uploaded to convert them?

No. The FFmpeg engine runs inside your browser tab, so the video is processed locally. This is why there is no upload progress bar — the file never leaves your computer or phone.

Why is the first conversion slower?

The first time you use a video tool, the browser downloads the FFmpeg engine (around 30 MB) and caches it. After that, conversions start much faster because the engine is already loaded.

Which video format works almost everywhere?

MP4 (H.264) is the most universally compatible — it plays on virtually every phone, browser, TV and editor. Convert to MP4 when you just need something that reliably opens.
