The Cuts People Actually Make
Most trims are one of a handful: a ringtone from a song's best 30 seconds, a voice note trimmed to the answer instead of the twenty seconds of shuffling before it, a podcast segment isolated for a clip, a sound effect pulled out of a longer recording, or the dead air at both ends of a lecture recording removed. All of them need the same two decisions — where it starts and where it ends — and this tool gives you both with second precision and a preview player to find the exact spots.
The preview matters more than it sounds. Numbers alone make trimming guesswork: play the file, note roughly where the part you want begins, type a value, then play again around that point and adjust. A cut that starts half a second early keeps a breath or a click; one that starts late clips the first word. Two or three small corrections are normal and take seconds each.
Under the hood, trimming re-encodes the selected range into a fresh file — the output is a clean MP3 or WAV containing exactly what you kept, with nothing before or after. The original file on your device is untouched, and because only the kept range is processed, trimming a short section out of a long recording is quick.
Everything runs in your browser — the file is decoded locally, cut and saved. Nothing is uploaded, which is exactly what you want for recordings of meetings, calls and voice notes.
Frequently Asked Questions
Use the preview player on the page — play the file, note the seconds where your part begins and ends, then type those values. Adjust by fractions of a second if the cut clips a word.
One range per pass. Trim the first section, download, then run the original through again for the next one.
The kept audio is re-encoded once at your chosen quality — at 192 kbps or higher MP3, or in WAV, the difference is not audible.
Your choice of MP3 (with bitrate control) or WAV (lossless). MP3 is the practical default for sharing.
