Why Our Video Converter Stands Out: Every Format, One Browser Tab

One Tool, Every Format
MP4, MOV, AVI, MKV, and WebM are all supported as both input and output, so whatever format you're stuck with, you can get to whatever format you actually need.
Genuine FFmpeg Conversion
Video Converter runs FFmpeg compiled to WebAssembly, giving you the same underlying encoder used by professional desktop software — right in your browser tab.
Watch It Happen Live
A real-time progress bar shows exactly where the conversion stands, so you're never left guessing whether a large file is still working or has stalled out.
Private, Fast, and Free
Everything happens on your own device, with no account, no watermark, and no upload wait — just drop a file in and convert it.
