Frequently asked questions

Why WAV out and not MP3?: WAV is lossless and needs no encoder — the trim happens sample-accurate with no quality loss. If you need MP3, run the WAV through the Audio / Video Converter tool afterwards.
Any file size limit?: Practical limit is your device's memory. A 30-minute stereo MP3 decodes to roughly 300 MB of PCM data in RAM.
Are my files uploaded to a server?: No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.
Does it work on mobile?: Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
