FLAC

FLAC (Free Lossless Audio Codec) is an open-source lossless audio format that compresses audio without discarding any information, typically reducing file size by 50-60% compared to WAV while allowing perfect reconstruction of the original signal. FLAC is the preferred format for high-fidelity music archives and audiophile collections.

Frequently Asked Questions

Is converting CAF to FLAC free?
Yes. This CAF → 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 CAF 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 CAF files uploaded to a server?
No. Files never leave your device. The entire CAF → FLAC 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 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 CAF to FLAC lose quality?
No. FLAC is a lossless format (or used in a lossless mode here), so the original data from your CAF file is preserved bit-for-bit in the converted result.
Does FLAC support transparency?
No — FLAC 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 FLAC?
Both formats use comparable compression, so the FLAC output will be similar in size to your CAF file — typically within 10–20% of each other.
