How it works
Trimming audio is how you get a ringtone out of a song, a usable clip out of a two-hour interview, or the silence off the front of a voice memo. Recordings are also among the most personal files people handle, which makes uploading them to a free website an odd first step.
Exact cuts
The section is re-encoded rather than copied, so the cut falls precisely where you put the handle instead of snapping to the nearest frame boundary. For speech especially, that difference is audible.
What you get back
An MP3 at 192 kbps, which plays on everything and is transparent enough for music and speech alike. The original file is left untouched.
Formats it reads
MP3, WAV, M4A, FLAC, OGG, AAC, WMA, Opus, AIFF and AMR go in. Your browser may not be able to preview every one of them — WMA and AMR in particular have no browser decoder — but ffmpeg can still cut them, and the tool falls back to plain second boxes when there is no preview.
It runs on your device
Nothing is uploaded, so there is no waiting for a transfer. The encode itself uses your own processor, which for audio is quick even on a phone.
Trim audio — questions
Is my recording uploaded?
No. The trim runs inside your browser using ffmpeg compiled to WebAssembly.
Can I make a ringtone with this?
Yes — trim the section you want and download the MP3. Converting it to your phone's preferred format is a separate step.
Why can I not hear a preview of my file?
Some formats, such as WMA and AMR, have no browser decoder. The tool still cuts them; it just shows second boxes instead of a waveform preview.
Does trimming lose quality?
The kept section is re-encoded once at 192 kbps, which is a small loss you are very unlikely to hear.
