Audio Trimmer & Audio Cutter — Free

The audio trimmer supports MP3, WAV, M4A, and AAC — the most common audio formats. It also accepts MP4, MOV, AVI, and WMV if you want to trim the audio from a video file. Output is always in the same format as your uploaded file.

No. The audio cutter uses stream copy — it cuts the file without re-encoding, so the quality is preserved bit-for-bit. Re-encoding only happens in rare edge cases where the codec and container are mismatched.

The tool splits your audio at a single cut point, producing two separate files: the part before the cut and the part after. To cut a middle section, just trim twice — once at the start of the section, once at the end.

No. Your file is processed in a secure temporary location and permanently deleted as soon as you download both output files, or automatically within 60 minutes at the latest. We never store, share, or analyse your audio.

Completely free: no account, no credit card, no sign-up required. Just upload your audio, pick the cut point, and download.

You can upload audio files up to 1GB. This limit applies to all users with no account required.

Files are not deleted until both parts have been downloaded (or you download the ZIP). If you close the page without downloading, files are automatically purged within 60 minutes as a privacy safeguard.
