Free audio tools
Cut and convert audio on the device itself. No upload, no account, no credits.
Trimming and conversion
Audio trim opens a file, draws its waveform, and lets the user select the part to keep by dragging or by typing the start and end in seconds. The selection can be played to check it before export.
The same tool works as a converter: leave the whole file selected and export it as WAV, MP3, M4A, AAC, OGG, FLAC or WebM. Files up to 30 MB or five minutes are supported, mono or stereo.
Nothing is uploaded
Decoding, trimming and encoding all happen in the browser, so a private recording such as a voice memo, an interview or a rehearsal stays private, and there is no waiting for a server.
Works with the AI audio generator
Speech generated in the studio can be opened here to cut the silence at the start, keep one sentence, or convert it to the format an editor requires.

Do I need to sign in?
No. The tool works without an account and never uses credits.
Will trimming re-encode my audio?
The selection is decoded and encoded again in the format you choose. Pick WAV or FLAC when you need a lossless result.
