FLAC

Lossless
Compressed
Music archives

Lossless audio in about half the space of a WAV. FLAC keeps every sample but packs it tightly, which makes it the favourite for music collections and archives. Most players and Android phones play it; Apple Music and iTunes don't.

An FLAC is lossless, so it becomes WAV with every sample unchanged, and MP3, M4A and MP4 or another lossy format at the bitrate you choose — much smaller, with detail you're unlikely to hear left out.

FLAC files can be up to 2 GB. Safari reads a FLAC whole, so there it can be up to 200 MB and 30 minutes.
Making M4A, MP4, M4B or AAC needs the browser's AAC encoder (Chrome, Edge and Safari — not Firefox yet); OGA and WEBA its Opus encoder; MP3, WAV and FLAC are made in any modern browser.

How to do it

Choose your FLAC files, or drop them on the page — as many as you like.
Each starts as an MP3; pick another format for every file with Convert to in Settings, or for one file on its row.
Convert all, then download each file, or all of them in one .zip.
