Frequently Asked Questions

Is converting OGG to M4R free?

Yes. This OGG → M4R 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 OGG to M4R?

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 OGG files uploaded to a server?

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

Can I convert multiple OGG files at once?

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

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

Does M4R support transparency?

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

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

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