M4A to MP3 — domande frequenti

Does this work with iPhone voice memos?+

Yes — voice memos are M4A/AAC, which this decodes in your browser and re-encodes as MP3.

Is my file uploaded?+

No. Decoding and encoding both happen entirely on your device.

Will it play everywhere after converting?+

MP3 is the most universally supported audio format, so yes — anywhere M4A might be refused, the MP3 will play.

Any quality loss?+

Converting between two lossy formats adds a little loss. Pick 256–320 kbps to keep it minimal.

Caricate i miei file su un server?+

No — ogni strumento qui elabora i tuoi file interamente sul tuo dispositivo, e non viene caricato nulla su un server. L'unica eccezione sono gli strumenti IA, che inviano il testo estratto (non il file) a Claude per svolgere il loro lavoro.

C'è un limite di dimensione del file?+

Non imponiamo alcun limite artificiale, ma poiché l'elaborazione avviene nel tuo browser, i file molto grandi (oltre 500 MB o 1.000 pagine) sono limitati dalla memoria del tuo dispositivo, non da noi.
