Frequently Asked Questions
Can I use this to trim MP3 files?
Yes. Drop any MP3 file onto the upload area, drag the handles to set your trim range, and export as WAV. The browser decodes the MP3 natively so no conversion step is needed.
Can I trim WAV files?
Yes. WAV files load and decode instantly since they are already uncompressed PCM. The exported WAV is a direct sample-accurate slice of the original, with no quality loss.
What audio formats are supported?
Any format your browser's built-in codec can decode: typically MP3, WAV, OGG, FLAC, M4A, and AAC. The exported file is always a WAV.
How precise is the trim?
The numeric input fields let you set start and end times to one decimal place (0.1 s). The underlying sample-level copy is accurate to a single audio sample at the file's native sample rate.
Why is the exported WAV larger than the original file?
WAV is an uncompressed format. The original file may have been an MP3 or OGG compressed to a fraction of the size. Run the exported WAV through an audio converter if you need a smaller file.
Can I trim very long audio files?
The tool loads the entire file into memory as a decoded PCM AudioBuffer. Files up to around 30 to 60 minutes work fine on most modern devices. Very long files may cause the browser to run low on memory.
