Questions
- Can I convert iPhone Voice Memos?
- Yes. In Voice Memos, share the recording and save it to Files (or send it to your computer), then choose the .m4a file here.
- Which M4A files work?
- M4A with AAC sound — what Voice Memos and most recorders and apps save. Apple Lossless (ALAC) M4A isn’t readable in every browser; if yours can’t read it, the tool tells you so.
- How big will the WAV be?
- About 5 MB per minute for mono and 10 MB for stereo (44.1 kHz). The tool makes WAV files up to 1 GB — about an hour and a half of stereo.
- Are my files uploaded anywhere?
- Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.
