Audio Trimmer
Trim a clip from an audio file without uploading it anywhere. Set the start and end points and FileTinker cuts it in your browser, then exports an MP3 — your audio never leaves your device.
How to cut an audio file
- Add your MP3, WAV, M4A or OGG above (or tap to browse). Nothing uploads — the file is decoded straight into your browser.
- Drag the start and end sliders to the exact section you want to keep, scrubbing to fine-tune where the clip begins and ends.
- Press Cut and download. FileTinker trims your selection and exports it as an MP3, ready to play anywhere.
About cutting audio
An audio trimmer lets you keep just the part of a track you need — a ringtone, a podcast quote, a sample, or the silence at the start of a recording. FileTinker accepts any format your browser can decode, including MP3, WAV, M4A and OGG, and always exports the result as a 128 kbps MP3 that opens on phones, players and editors alike. The cut itself is precise to the points you choose on the timeline.
Because decoding, trimming and MP3 encoding all run in your browser, your audio never touches a server and nothing is stored online. That keeps voice memos, interviews and unreleased music private. Trimming is lossless up to the export, where the file is re-encoded at 128 kbps — a balance of quality and size that suits most everyday clips.
