Secure Multi-Format Converter

Browser-native media conversion for images, video, and audio with private local processing, batch queueing, and encrypted recipe sharing.

Universal Studio

Add 20+ files, pick a conversion recipe, and run the queue locally without uploading any media.

Drag-and-drop style batch queue

This free build runs conversions in browser memory using canvas, MediaRecorder, and Web Audio. It is private and offline-friendly, but not a full FFmpeg.wasm replacement yet.
