Convert MPEG to FLAC — Free Online Converter

MPEG files store audio as MPEG Audio Layer 2 (MP2), a perceptual codec that discards frequencies most listeners cannot hear. FLAC (Free Lossless Audio Codec), released in 2001, provides bit-perfect audio compression with typical ratios of 50-70%. Converting MPEG to FLAC extracts the audio track and wraps the decoded PCM in a lossless, open-source container.

When you need to edit, process, or archive audio extracted from MPEG video files, FLAC offers the best balance of quality preservation and storage efficiency. Unlike WAV or AIFF, FLAC compresses the audio by roughly half without discarding a single sample. Unlike AAC or MP3, FLAC introduces zero generational loss, making it safe for repeated editing and re-encoding.

FLAC is also the archival format of choice for libraries, museums, and broadcast organizations. If you are digitizing a collection of MPEG-1 VCD recordings or MPEG-2 broadcast captures, converting the audio to FLAC ensures the best possible preservation of the decoded audio for future use, regardless of how many times the files are accessed or processed.
