Frequently Asked Questions

Is converting M4A to AIFF free?

Yes. This M4A → AIFF converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert M4A to AIFF?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my M4A files uploaded to a server?

No. Files never leave your device. The entire M4A → AIFF conversion runs locally in your browser, so your data stays private.

Can I convert multiple M4A files at once?

Yes — batch conversion is supported. Add as many M4A files as you like and convert them to AIFF in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting M4A to AIFF lose quality?

No. AIFF is a lossless format (or used in a lossless mode here), so the original data from your M4A file is preserved bit-for-bit in the converted result.

Does AIFF support transparency?

No — AIFF has no alpha channel. Transparent areas of your M4A file will be filled with a solid background colour in the converted file.

How will the file size change after converting M4A to AIFF?

Both formats use comparable compression, so the AIFF output will be similar in size to your M4A file — typically within 10–20% of each other.
