Frequently asked questions
Is my file uploaded to a server?
No. The converter (FFmpeg compiled to WebAssembly) runs inside your browser, so the file never leaves your device. That also means there is no upload wait, even for big videos.
Does it work with iPhone voice memos?
Yes. Voice Memos are M4A files and convert directly.
Is the WAV better quality than the M4A?
It’s the same audio, stored uncompressed. WAV can’t add detail, but it avoids any further loss when editing.
