Frequently Asked Questions

Is converting CAF to WMA free?
Yes. This CAF → 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 CAF 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 CAF files uploaded to a server?
No. Files never leave your device. The entire CAF → WMA conversion runs locally in your browser, so your data stays private.
Can I convert multiple CAF files at once?
Yes — batch conversion is supported. Add as many CAF 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 CAF 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 CAF file. Avoid repeated re-encoding to keep the best quality.
Does WMA support transparency?
No — WMA has no alpha channel. Transparent areas of your CAF file will be filled with a solid background colour in the converted file.
How will the file size change after converting CAF to WMA?
Both formats use comparable compression, so the WMA output will be similar in size to your CAF file — typically within 10–20% of each other.
