The audio cutter lets you trim any MP3, WAV, OGG, FLAC, M4A or AAC file directly in your browser, with nothing to install and no upload to any server. Drag your audio, move the start and end sliders (or type the exact seconds), and download the result. Fast mode uses FFmpeg's stream copy to cut without re-encoding, ideal when you just need to remove silence at the start or end; precise mode re-encodes the segment for an exact cut down to the second. All processing runs with FFmpeg compiled to WebAssembly inside your own browser — your file never leaves your device.

Frequently asked questions
Is my audio uploaded to a server?
No. All the cutting is processed with FFmpeg compiled to WebAssembly inside your browser. The file never leaves your device.
What's the difference between fast and precise mode?
Fast mode copies the audio without re-encoding it (faster, the cut may vary slightly). Precise mode re-encodes the segment for an exact cut to the second, a bit slower.
What formats does it support?
MP3, WAV, OGG, FLAC, M4A and AAC. The result downloads in the same format as the original file.
Is there a size limit?
Yes, 300 MB per file, enough for practically any audio or podcast.
