Audio Converter — preguntas frecuentes

Is my audio uploaded?+

No. The file is decoded and re-encoded entirely in your browser using the Web Audio API — it never leaves your device. There's no ffmpeg and no server.

Which formats can I convert from?+

Anything your browser can decode — MP3, WAV, M4A/AAC, FLAC and OGG all work. Output is MP3 or WAV.

Why no FLAC or OGG output?+

Those need a separate encoder that would add a large download. MP3 (via a small in-browser encoder) and WAV (native) cover the common cases without the weight.

Is there a length limit?+

No fixed limit, but a very long file is held in memory while it's processed, so extremely large files depend on your device's RAM.

¿Suben mis archivos a un servidor?+

No: todas las herramientas procesan tus archivos por completo en tu dispositivo y nada se sube a un servidor. La única excepción son las herramientas de IA, que envían el texto extraído (no el archivo) a Claude para hacer su trabajo.

¿Hay un límite de tamaño de archivo?+

No imponemos un límite artificial, pero como el procesamiento ocurre en tu navegador, los archivos muy grandes (más de 500 MB o 1000 páginas) están limitados por la memoria de tu dispositivo, no por nosotros.
