What is the Video Converter?

The video converter works like this: it re-encodes video files between MP4, WebM and GIF with resolution and quality control, using in-browser FFmpeg. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

How to use the Video Converter

1. Select your audio or video file.
2. Set the conversion options (format, quality, range).
3. Process - the browser engine handles it locally.
4. Download the output.

Frequently asked questions

Why convert to MP4 H.264?

It plays in every browser, TV and phone made in the last decade - the safest delivery format that exists.

Which formats convert between?

MP4, WebM and GIF, with resolution and quality control - the re-encoding runs entirely in your browser.

How do I choose the output resolution?

Match the destination platform rather than maxing it - a 1080p output from a 720p source gains nothing but file size.
