Best Free Video Converter

How it works

1. Upload. Choose a short video clip (up to 100 MB).
2. Pick a format. Select MP4, WebM, MKV, MOV or animated GIF.
3. Download. The converted video downloads automatically; nothing is stored.

About this tool

Video Converter re-encodes a video clip into a different format: MP4 for maximum compatibility, WebM for the web, MKV or MOV, or an animated GIF from a short clip. It runs the conversion server-side with ffmpeg under a strict size cap and a hard time limit, so the free tier stays fast and fair for everyone. It's sized for short clips and quick format changes rather than feature-length films. No watermark, no signup, and your file is converted in a temporary workspace and deleted immediately.

What people use it for

• Convert a clip to MP4 so it plays everywhere
• Make a WebM for a lighter web video
• Turn a short clip into an animated GIF
• Change a phone video’s format for an app that rejects it
