Convert M4A to MP3

The iPhone saves voice memos as M4A. Fine on a Mac, but some car stereos, older players and upload forms do not know the format. As MP3 it works everywhere. MP3 is already set.

How does this tool work?

Converts files across multiple domains (3D/CAD meshes, video, raster & vector graphics, firmware & ROMs, structured datasets, documents, audio) directly in your browser.

Drop files into the upload zone or select them via file picker. The tool automatically detects each file category and populates compatible target formats. Convert files individually or in batch with a live progress bar, then download them one by one or bundled into a single ZIP archive. All processing runs 100% locally on your machine.

Where are my data processed?
