Quick answer: To send a large FLAC file, upload it to Share Large Video Files (up to 20 GB, no account) and share the download link: the file arrives unchanged. A CD-quality FLAC album is about 300 MB, more than most email providers accept.
What is a FLAC file?
FLAC is a lossless compressed audio format. It keeps every detail of the original recording, like WAV, but typically takes around half to two thirds of the space. Music collectors, hi-res download stores and musicians sharing masters use it.
FLAC is still much larger than MP3 or AAC because nothing is thrown away. Hi-res FLAC (24-bit at 96 or 192 kHz) is several times bigger than CD-quality FLAC, so a single album can pass 1 GB.
Extensions: .flac.

Tips for sending FLAC files
- Keep the album folder with its cover art and any cue or log files.
- Do not convert FLAC to MP3 and then back; the loss cannot be undone.
- For Apple Music users, mention ALAC as the lossless alternative that iTunes and Music accept.
- Zip the album so track order and folder names stay tidy.
How to open a FLAC file

Frequently asked questions
Is FLAC the same quality as WAV?
Yes. FLAC is lossless, so it decodes to exactly the same audio as the WAV it came from, in less space.
Can I play FLAC on an iPhone?
Yes, in the Files app and in third-party players such as VLC. The Apple Music app will not import FLAC.
Will zipping FLAC files make them smaller?
Barely. FLAC is already compressed. Zip only to bundle an album into a single download.
