Convert M4A files into uncompressed WAV that every editor and DAW can handle directly. Conversion runs in your browser, so your recordings are never uploaded.
In “Local” mode your file never leaves your device. No uploads, no server – ideal for sensitive recordings.
Pick “Local” for full privacy or “Server” for very large files and every format.
No sign-up, no queue, no watermark. Choose a file, convert, download.

No, conversion runs directly in your browser by default. For very large files there is an optional server mode.
