Audio Tools

Convert, trim, merge, boost, and edit audio files in your browser.

10 tools available

Edit sound files without installing software or uploading a single sample. Convert between MP3, WAV, OGG, and AAC, trim a clip to exactly the section you need, merge multiple recordings into one track, boost or normalize volume to a professional loudness standard, compress files to a fraction of their size, strip silent gaps automatically, change playback speed without altering pitch, reverse audio, add smooth fades, and cut songs into iPhone or Android ringtones. These tools run FFmpeg - the industry-standard audio engine - directly in your browser through WebAssembly, so your recordings never leave your device. That makes them safe for voice memos, interviews, meetings, and anything private. No signup, no watermarks, and no file-size paywalls.
