Frequently Asked Questions

Is converting WAV to CAF free?

Yes. This WAV → CAF 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 WAV to CAF?

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 WAV files uploaded to a server?

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

Can I convert multiple WAV files at once?

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

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

Does CAF support transparency?

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

Will the converted CAF file be smaller than the WAV?

Usually yes. Converting from a lossless or uncompressed format to a lossy one dramatically reduces file size. Typical savings range from 50% to 90%, depending on the quality setting you choose.
