Frequently Asked Questions

Yes. This tool uses Web Audio API entirely within your browser. No files are uploaded to any server. All processing happens on your device.

Technical Constraint: Encoding MP3 requires complex external libraries (like LAME.js) which are heavy to include in a single file.

To keep this tool lightweight and 100% client-side, we use the native WAV encoder. WAV is lossless and provides the highest possible quality from your source file.

Since we use your browser's RAM (Memory), very large files (e.g., >200MB or 1 hour long) might crash the tab on mobile devices. For best results, use files under 50MB.
