Frequently Asked Questions
Which audio formats can I upload?
You can upload MP3, WAV, OGG, M4A, AAC and FLAC files. The trimmed output is always saved as a WAV file, which plays in every major app and browser.
Is my audio uploaded to a server?
No. Everything runs entirely in your browser using the Web Audio API. Your audio never leaves your device — there are no servers, no cookies and no tracking.
Why is the output always a WAV file?
WAV is an uncompressed PCM format that browsers can write natively without external libraries. It is lossless, universally compatible, and requires no encoding step.
How accurate is the trim?
The trim is sample-accurate. Start and end times are converted to the exact sample index in the audio buffer before exporting, so there is no rounding to frame boundaries.
What is the maximum file size?
Files up to 200 MB are supported. Very large files may take a few seconds to decode. All processing happens locally — there are no server-side size limits.
