Frequently asked questions
What formats can I trim?
Any audio format your browser supports: MP3, WAV, OGG, FLAC and M4A are typically supported. The output is always a WAV file.
Is there a maximum file length?
No fixed limit, but the entire file is decoded into memory. Very long recordings (hours) may be slow to process in-browser.
Is my audio uploaded to a server?
No — trimming happens entirely in your browser using the Web Audio API. Your file never leaves your device.
Can I trim multiple clips from one file?
One clip at a time — adjust the handles and click Trim to download each clip separately.
