Audio & Video Converters
Convert audio between MP3, WAV, OGG, FLAC and M4A in any direction, rescue older formats like WMA, turn WhatsApp voice notes out of Opus, trim a track, or pull the audio out of a video — plus video clips to GIF. All of it is powered by ffmpeg compiled to WebAssembly and running entirely on your device. The first conversion loads a one-time engine (a genuine trade-off for never uploading your media); every conversion after that reuses it.
