How to Trim Audio Online
Upload your audio file by dropping it into the zone above or clicking to browse. The tool decodes the audio using your browser's built-in Web Audio API — which supports MP3, WAV, OGG, FLAC, AAC, M4A, and most other common formats. Once loaded, the full waveform is drawn on a canvas so you can see exactly where the audio content starts and ends.
Drag on the waveform to highlight a region to keep, or use the Start and End sliders below the waveform for fine control. Click Play to preview the trimmed section before exporting. When you're happy with the result, choose an output format and click Download. The trim is applied in-browser in milliseconds using the Web Audio API — no server needed.

Frequently Asked Questions
What audio formats can I trim?
Any format your browser can decode: MP3, WAV, OGG, FLAC, AAC, M4A, WebM, and more. The actual format support depends on your browser, but all major formats work in Chrome, Firefox, and Safari.
Does trimming reduce audio quality?
Exporting to WAV is completely lossless — there is no quality loss. Exporting to MP3 re-encodes the audio, which introduces minor compression artifacts. For critical work, export to WAV and convert separately if needed.
Can I trim to an exact timestamp or millisecond?
Yes. The sliders step in small increments, and you can drag directly on the waveform for visual precision. The time display updates in real time as you adjust.
Is there a maximum file size?
There is no server-side limit. The practical limit is your device's available RAM. Most computers can comfortably trim files up to a few hours in length.
Can I make multiple cuts or remove a section from the middle?
This tool trims start and end only. To remove a section from the middle or make multiple cuts, use the Waveform Editor.
