Need help?MPEG to FLAC Converter
This tool extracts the audio track from an MPEG video and saves it as a FLAC file. MPEG (the .mpeg / .mpg container — the two extensions are the same format, just spelled differently) is an MPEG-1 or MPEG-2 Program Stream whose audio is almost always MP2 (MPEG-1 Audio Layer II) or AC-3 (Dolby Digital). FLAC is the Free Lossless Audio Codec. The conversion keeps the soundtrack and discards the video, packaging the audio in a lossless container that survives repeated editing and re-saving without further generational loss.
One honest caveat up front: MP2 and AC-3 are lossy codecs, so the audio inside an MPEG was already compressed once. Wrapping it in FLAC makes the result lossless from this point forward — it does not rebuild detail that was thrown away at the original encode. The benefit is archival stability and clean re-editing, not recovered fidelity. If you only need a small, broadly compatible file, convert MPEG to MP3 instead.

How to Convert MPEG to FLAC
- Upload Your MPEG File: Drag and drop your
.mpegor.mpgfile onto the page, or click "+ Add Files" to browse. Multiple files can be queued and processed with the same settings. - Set the Compression Level: Use the Compression level slider (1-12) under Advanced Options. A higher number produces a smaller file but takes longer to encode; because FLAC is lossless, this slider never changes the audio quality.
- Adjust Audio Channel or Sample Rate (Optional): Leave Audio Channel and Audio Sample Rate on "Original" to preserve the source exactly, or use the Trim control to keep only part of the track.
- Convert and Download: Click "Convert" and download your FLAC file. No sign-up, no watermark.
Frequently Asked Questions
Will converting MPEG to FLAC improve the audio quality?
No. The MPEG soundtrack is already lossy MP2 or AC-3, and FLAC cannot reconstruct detail that the original encoder discarded. FLAC guarantees no further loss — useful when you plan to edit or re-export the audio repeatedly — but it cannot make a 192 kbit/s MP2 track sound like a studio master. For pure archiving with no later editing, the lossless wrapper still prevents generational degradation.
Is .mpeg the same as .mpg for this conversion?
Yes. .mpeg and .mpg are two spellings of the same MPEG Program Stream container, so this tool accepts both and treats them identically. The MPG to FLAC page is the same converter under the other extension name.
What audio codec is inside a typical MPEG file?
Most often MP2 (MPEG-1 Audio Layer II), commonly at 192-384 kbit/s. MPEG-2 Program Streams ripped from DVDs frequently carry AC-3 (Dolby Digital) instead, which DVD-Video caps at 448 kbit/s. The converter reads whichever stream is present and decodes it before re-encoding to FLAC.
Does the FLAC keep the original sample rate and channels?
Yes, when Audio Channel and Audio Sample Rate are left on "Original." MP2 and AC-3 in MPEG are typically 48 kHz, and a Dolby Digital track may be stereo or up to 5.1. FLAC preserves the source sample rate and channel count unless you deliberately override them.
Why is the FLAC file larger than the original MPEG audio?
Because lossless storage costs more bits than lossy storage. A 192 kbit/s MP2 stream re-encoded to FLAC can grow because FLAC must represent the decoded waveform exactly rather than approximating it. In our testing, a DVD-sourced AC-3 stereo track produced a FLAC several times the size of the compressed source — expected behavior, not an error.
Does the higher compression level reduce sound quality?
No. The Compression level slider only trades encoding time for file size; every level decodes to bit-identical audio. A higher number shrinks the file at the cost of slower processing, which is why the page notes it "doesn't effect the audio quality."
What happens to my file after conversion?
Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up, no watermark, and files are never shared or made public.
