Shrink WAV files without losing a single sample. FLAC is lossless: Solmi reads the PCM samples of your WAV in the browser and compresses them into a FLAC that decodes back to exactly the same audio, usually 30 to 50 percent smaller. No upload, no signup, no watermark.
1. Choose the WAV from your computer or phone. 2. Press Convert. The samples are compressed into FLAC in your browser; nothing uploads. 3. Play the FLAC on the page, then download it.
Both hold the same full-quality audio. FLAC packs it smaller and can prove it is intact.
| Feature | WAV | FLAC |
|---|---|---|
| Compression | None | Lossless, usually 30 to 50% smaller |
| Audio | Original samples | The same samples |
| Integrity check | None | MD5 of the audio in the header |
| Best for | Editing, samplers, older software | Archiving, music libraries, streaming at home |
Drop the WAV onto the converter and press Convert. Solmi reads the samples, compresses them with a FLAC encoder that runs in the page, and gives you the .flac to play or download. Nothing is uploaded.
Yes. FLAC stores the exact samples, the way a ZIP file stores exact bytes. An 8, 16, or 24-bit PCM WAV decodes back from the FLAC sample for sample, and the file carries an MD5 checksum of the audio so players and tools such as flac -t can confirm it.
Usually 30 to 50 percent smaller for music, more for speech or quiet recordings, less for dense, loud masters. A 50 MB WAV of a pop song typically becomes a FLAC of 25 to 35 MB.
FLAC stores whole-number samples only, so 32-bit float and 32-bit integer WAVs, which some DAWs export, are saved as 24-bit FLAC. That keeps far more resolution than anyone can hear, but it is not bit-identical; keep the original if you need the float file.
FLAC takes less space for the same sound, plays in most music players, phones, and media servers, and checks itself for corruption. WAV is still the safer choice for some samplers and older software, so keep a WAV for any tool that asks for one.
No. The converter runs entirely in your browser: your file is decoded and re-encoded on your own device, and nothing is sent to a server. That is also why it is fast — there is no upload wait and no download wait, just the conversion itself.
Yes, completely free with no signup, no file-size paywall, and no watermark. Once your audio is converted, you can turn the track into a music video with Solmi's AI music video generator — also free to start.
