What Is Audio Trimming?
Audio trimming cuts a specific portion from an audio file by setting start and end times. This browser-based audio trimmer uses FFmpeg WebAssembly to process MP3, WAV, OGG, and other audio formats directly in your browser. It is useful for creating ringtones, extracting clips from podcasts, removing silence from recordings, or cutting intros and outros. Your audio files are processed locally and never uploaded to any server.

Why Use Our Audio Trimmer?
Frequently Asked Questions
What audio formats can I trim?
The trimmer supports all common formats including MP3, WAV, OGG, FLAC, AAC, and M4A. The output preserves the original format and quality.
Is there a file size limit?
There is no enforced limit. Processing happens on your device, so the practical limit depends on your available memory. Files up to several hundred MB work well on modern devices.
Can I trim audio without quality loss?
Yes. When possible, the trimmer uses stream copying which cuts the audio without re-encoding, preserving the original quality exactly.
Does this work offline?
Yes. After the page loads and the WebAssembly module is cached, trimming works without an internet connection.
