How to use this tool
- Choose files or drag them into the workspace. Matching inputs get the output format shown on this page.
- Check the output format and image quality for each file. Existing files in your queue keep their settings.
- Start the conversion, then download individual results or the completed batch. Your original files are unchanged.
Quality and format notes
FLAC compresses WAV exactly: every sample survives decoding, typically at around half the size. The natural move for archived recordings that currently sit as heavy WAV files.
FLAC plays on computers, phones and modern players; a few exotic hardware players still want WAV. Keep a WAV copy only for those specific targets.
Frequently asked questions
Is FLAC really lossless?
Yes. A decoded FLAC is bit-identical to the source WAV — checksums match — which is why it is the standard archive format for audio.
How much smaller will my files get?
Typically 40–60% of the WAV size depending on content complexity. The workspace reports each result's actual size.
Can I convert back to WAV later?
Yes, exactly. FLAC to WAV restores the identical samples, so converting to FLAC is reversible in a way lossy formats are not.
