All Audio tools

Edit audio without installing anything

These audio tools decode your file with the browser's Web Audio API, edit it on your device and encode the result as MP3 or WAV. There's no software to install and no upload queue, and recordings such as voice memos, interviews or lectures stay private.

Audio Cutter trims a song or recording on a visual waveform with fade in and fade out, which also makes it a quick ringtone maker. Audio Joiner combines several tracks into one with an optional gap or crossfade, even when they use different formats or sample rates.

Audio Speed Changer speeds up or slows down audio between 0.5x and 2x, with pitch lock so voices keep their natural tone. Volume Booster makes quiet recordings louder with a limiter that prevents clipping, or normalizes the peak level. Reverse Audio plays any file backwards for sound design and effects. All five tools are free, need no sign-up and add no watermark or jingle to your audio.
