What audio formats are supported?

You can upload MP3, WAV, OGG, AAC, and FLAC files. The output is always exported as a lossless WAV file.

Does trimming change the audio quality?

The trimmed audio is exported as an uncompressed WAV file, so there is no re-encoding quality loss. If you uploaded a lossy format like MP3, the WAV export will be as good as the source.

How precise are the time controls?

The sliders allow frame-level precision. You can also type exact timestamps directly into the time fields for sample-accurate trimming.

Is my audio file uploaded to a server?

No. All processing happens entirely in your browser using the Web Audio API. Your file never leaves your device.

Can I trim the same file multiple times?

Yes. After downloading, you can re-upload the WAV and trim again to refine your cut further.
