Browser-based video tools
Single-purpose tools, each one a thin UI over FFmpeg.wasm. Files are processed inside the browser tab — nothing is ever uploaded. The main MP4 / MKV / MOV converter lives on the homepage; everything else is here.
- MP4 Converter
MP4 Converter
Convert between MP4, MKV, MOV, AVI and more. Stream-copy when possible (instant, lossless), or pass custom FFmpeg arguments for full control over codec, bitrate, and resolution. No upload.
Open tool → - Compress for WhatsApp
Video Compressor
Compress an MP4 to a target file size — WhatsApp 16 MB, Discord 25 MB, custom — without uploading. Single-pass H.264, target-size or CRF-quality modes.
Open tool → - MOV → MP4
MOV to MP4 Converter
Convert MOV (QuickTime, iPhone) to MP4 in seconds. Default stream copy keeps quality identical; optional re-encode for older devices.
Open tool → - Video → GIF
Video to GIF Converter
Turn an MP4, MOV, MKV, or WebM clip into an animated GIF directly in your browser. Two-pass palette generation for sharper colour. No upload.
