Your data never leave your device

All processing runs directly in your browser using built-in Web APIs — the Canvas API, Web Audio API, and WebAssembly. Nothing is uploaded to any server. There is no account, no email, and no data retention. You can verify this yourself: open your browser's DevTools Network tab and watch zero outbound file requests while the tool processes your data.

GDPR-friendly · Works offline after page load · No file size limits beyond your device memory
