Frequently Asked Questions

Is converting WMA to FLAC free?

Yes. This WMA → FLAC 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 WMA to FLAC?

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 WMA files uploaded to a server?

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

Can I convert multiple WMA files at once?

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

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

Does FLAC support transparency?

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

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

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