About formats

WAV

WAV (Waveform Audio File Format) is a raw, typically uncompressed audio container developed by Microsoft and IBM based on the RIFF structure. WAV preserves full audio fidelity and is the format of choice for studio recording, archival, and professional audio editing, although file sizes are much larger than compressed formats.

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