Video Converter

Overview

This browser-based video converter uses WebAssembly (FFmpeg) to transcode between all major formats — MP4, WebM, AVI, MOV, MKV, WMV, FLV, M4V, 3GP, and animated GIF — without sending a single byte to a server. Everything runs locally on your device, so conversion is private by design: no account required, no file size caps tied to subscriptions, and no waiting in a cloud queue. Batch-convert multiple files at once and download each result as soon as it is ready.

Share Videos Cross-PlatformConvert AVI or WMV files recorded on Windows to MP4 so they play natively on iPhones, Android devices, and modern browsers without extra software.
Create Animated GIFsTurn short video clips into animated GIFs for social media posts, chat reactions, or web embeds where full video is overkill.
Prepare Web-Optimized VideoConvert heavy MOV or MKV files to WebM for dramatically smaller file sizes and faster page loads when embedding video on a website.
Batch-Convert a Camera RollDrop multiple videos at once and convert them all to the same output format in a single pass — useful when migrating footage from one device ecosystem to another.
Privacy-Sensitive FootageConvert dashcam, home security, or medical video clips that must never leave the device by processing everything locally in the browser.
