Frequently Asked Questions

Is converting M4R to WMA free?

Yes. This M4R → WMA 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 M4R to WMA?

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 M4R files uploaded to a server?

No. Files never leave your device. The entire M4R → WMA conversion runs locally in your browser, so your data stays private.

Can I convert multiple M4R files at once?

Yes — batch conversion is supported. Add as many M4R files as you like and convert them to WMA 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 M4R to WMA reduce the quality?

Because both formats use lossy compression, the WMA output will not bring back any quality that has already been lost in your M4R file. Avoid repeated re-encoding to keep the best quality.

Does WMA support transparency?

No — WMA has no alpha channel. Transparent areas of your M4R file will be filled with a solid background colour in the converted file.

How will the file size change after converting M4R to WMA?

Both formats use comparable compression, so the WMA output will be similar in size to your M4R file — typically within 10–20% of each other.
