WebToolsHUBHow to trim audio and make a ringtone
- Load an audio file — MP3, M4A, OGG, FLAC or WAV, whatever your browser decodes.
- Set the start and end sliders until the highlighted region on the waveform covers the part you want.
- Press Play selection to hear exactly what will be exported, and adjust the edges if it is off.
- Add a little fade in and fade out (0.3-0.5 seconds works well) so the clip does not click at the cuts.
- Hit Export WAV and the trimmed clip downloads instantly — decoded, trimmed and encoded on your device.
Frequently Asked Questions
Which audio formats can I load?
Anything your browser can decode natively — typically MP3, M4A/AAC, OGG, FLAC and WAV. The tool reports the decoded details (duration, channels, sample rate) after loading, and an unsupported file fails with a clear message.
Why is the export WAV and not MP3?
WAV with 16-bit PCM is the lossless digital form Web Audio already produces, so exporting it adds no second lossy generation and requires no extra encoder. If you need a smaller file, run the WAV through the audio converter afterwards.
Is my audio uploaded to a server?
No. Decoding, waveform drawing, playback and the WAV encoding all happen locally via the Web Audio API — the file never leaves your device, which matters for voice memos and unreleased recordings.
Why do I hear clicks at the start and end?
A cut that starts or ends at full volume produces a sudden jump in air pressure that the ear reads as a click. A short fade of a few tenths of a second removes it — the fade controls exist exactly for this.
Is there a file size limit?
The limit is your device memory: the whole file is decoded into memory as raw samples, so a one-hour podcast uses far more RAM than its MP3 size suggests. For long recordings, split the work into shorter sections.
