This is the step where quality is actually decided. FLAC holds the full signal; MP3 throws away part of it to shrink the file, so pick the bitrate deliberately. Between 128 and 320 kbps covers most listening, and the file drops from around 6 MB per minute to roughly 1.7 MB per minute.
If your source runs above 48 kHz, it will be resampled: MP3 cannot store the 192 kHz that FLAC allows.
FLAC supports up to 8 channels, MP3 up to 2. Surround material is folded down rather than carried through untouched.
The two formats are aimed at different jobs. FLAC is typically used for long-term archiving, audiophile listening, CD ripping, while MP3 is the usual pick for music libraries, podcasts, sharing with anyone. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: Vorbis comments in the source becomes ID3v2 in the result. Standard fields map cleanly; niche custom tags often do not.
This page converts FLAC files, stored in the FLAC container since 2001, into MP3, which uses MPEG-1/2 Audio Layer III and dates from 1993. The differences between the two containers decide what changes in the result.
FLAC comes from Xiph.Org Foundation and dates to 2001. It holds losslessly compressed audio (FLAC), and that sets the ceiling for anything converted out of it.
MP3 comes from Fraunhofer IIS / MPEG and dates to 1993. It carries lossy-compressed audio (MP3), and without installing anything it plays on web browsers, Windows, macOS, iOS, Android, and smart TVs.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
