M4A is AAC audio in an MP4 container. It is efficient and widely supported on Apple devices, but some players, editors and upload forms only accept MP3.

Limitations

Up to 60 minutes and 500 MB per file.
Which input formats open depends on your browser: Chrome and Edge read the most formats.

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.

Frequently asked questions

Can I convert iPhone voice memos?

Yes. Share the memo to Files, then choose it here and convert it to MP3.

Are my files uploaded?

No. The audio is decoded and processed in your browser, so recordings and videos never leave your device.

Is it free?

Yes – free with no signup, no watermark and no daily limit.

How long can a recording be?

Up to 60 minutes per file (and 500 MB). The whole recording is held in your device’s memory while it is processed, so very long files need a computer rather than an older phone.
