Audio Cutter and Converter

Cut it. Convert it. Nothing uploaded.

Trim a song, voice memo or recording by dragging on the waveform. Fade the ends, change the volume, join several files, and save as MP3 or WAV. It also takes the sound track from video files. Everything happens on your device, so a private recording stays private.

Questions

Are my files uploaded?

No. The audio is decoded, cut and encoded in this page on your device. Nothing is sent anywhere.

Which files can I open?

Whatever your browser can play. Chrome and Edge open MP3, WAV, M4A/AAC, OGG, FLAC and the sound of most MP4, MOV and WebM files. Safari and Firefox differ. If a file will not open, try another browser or a WAV copy.

What sample rate does it use?

Your browser decodes every file at its own audio rate, usually 44100 or 48000 Hz, and the file is converted to that rate when it opens. Pick a sample rate in the output settings if you need a specific one. Files recorded at a higher rate, such as 96000 Hz, are not kept at that rate.

Does cutting lower the quality?

WAV output is not compressed again. MP3 output is encoded fresh from the decoded sound, so an MP3 saved from an MP3 loses a little quality each time. Use a high bitrate, or save WAV, if you will edit it again.

What does it not do?

MP3 and WAV exports use at most the first two decoded channels; extra surround channels are omitted. No M4A, AAC, OGG or FLAC output yet. No effects, noise removal, speed or pitch change. No video output. Very long recordings use a lot of memory because the whole file is decoded: an hour of stereo sound needs roughly 1.2 GB, so cut long files in parts on a phone.

Will the cut be exact?

The cut points are exact in the decoded sound. MP3 players may add a tiny gap at the start or end of an MP3 file, which is how the format works.
