MP3 first, other formats when supported
MP3 is the default. OGG, M4A, and WAV are also available, but acceptance depends on your phone and app. Common source formats include MP3, WAV, M4A, AAC, FLAC, and OGG, subject to browser decoding support.
Presets are not Android limits
The 30-, 8-, and 30-second type presets are starting selections, not universal Android duration rules. Short files use only the available audio. Larger sources still need device memory even if you keep only a short section.
Local processing and network imports
Local audio is decoded and edited in your browser. Cloud-drive and public-link imports use network requests. The encoder may download on first use. Save your finished file before closing the page.
Installation stays on your phone
The website cannot change system sounds or grant Android permissions. Your file manager, system settings, Contacts, or Clock app completes setup; menus vary by device and software version.
