VidShift
Convert video and audio files instantly in your browser - no upload needed
VidShift is a free, privacy-first video toolkit that converts, compresses, trims, and transforms video files entirely in your browser. No uploads, no servers, no sign-ups — just fast, secure video processing powered by WebAssembly.
Convert videos and extract audio instantly using your device's processing power. All processing happens locally via WebAssembly and WebCodecs, so your files never leave your computer — ensuring full privacy and security.
