Halve a WAV without losing anything
FLAC keeps every sample of the recording and still cuts the file roughly in half. The archive format for audio you may need again.
Runs in your browser. Your file never leaves your computer.
- QualityIdentical; bit-for-bit recoverable
- Typical sizeAbout half the WAV
- Plays onMost players; not old car stereos
- SettingsNone needed; trim is available
WAV stores audio with no compression at all, which makes it simple and huge. FLAC stores the identical samples with lossless compression, the way a ZIP stores a document: nothing is thrown away, and unpacking gives back the exact original. For recordings you want to keep, interviews, masters, vinyl rips, that trade is free space. The conversion runs in your browser, takes seconds for a song, and the result plays in every serious audio player and editor.
Questions
Is FLAC really lossless?
Yes. Decoding a FLAC gives back the exact samples that went in, verifiable bit for bit. It is compression like a ZIP, not like an MP3.
Why not just keep the WAV?
Space is the only difference. FLAC holds the same audio in about half the bytes and also carries tags, so titles and artists travel with the file.
What doesn't play FLAC?
Apple's own apps historically preferred ALAC, and some car stereos and old portable players skip FLAC files. For those, M4A or MP3 pages are one link away.
Is the file uploaded?
No. The WAV is read and re-encoded by your browser and the FLAC is saved straight to your disk. Nothing about it goes over the network.
