Frequently Asked Questions
Does this tool upload my audio file?
No. All processing happens inside your browser using the Web Audio API. Your file is never sent to any server.
Which audio formats are supported?
You can upload MP3, WAV, M4A, OGG, FLAC, AAC, OPUS, and most other common audio formats. Output can be saved as MP3 or WAV.
Is there a file size or length limit?
The tool works best with files under 200 MB. Very large files may be slower depending on your device's processing power, since everything runs locally.
Will it work on my phone or tablet?
Yes β the tool is fully responsive and works on iOS Safari, Android Chrome, and other modern mobile browsers.
What does Normalize do?
Normalization raises the loudest peak to just below 0 dBFS, making the clip as loud as possible without distorting. Useful when combining clips at different volume levels.
Is the MP3 export lossy?
Yes β MP3 is always a lossy format. Choose a higher bitrate (256 or 320 kbps) for better quality, or use WAV for a lossless copy of your trim.
Can I edit multiple sections from one file?
The tool trims one continuous selection per export. To extract multiple segments, simply adjust the selection and download each section separately.
