Add your MPG file
Drop one or more .mpg files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Pulling the soundtrack out of a .mpg video into .flac audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Pulling the soundtrack out of a .mpg video into .flac audio keeps what you can hear and drops the picture entirely. The .mpg extension is the three-letter spelling of .mpeg, applied to identical MPEG-1 or MPEG-2 program stream data. Files named .mpg and .mpeg are interchangeable at the byte level, so players and converters treat them the same and differ only in the label they display.
A .flac file contains audio compressed with the Free Lossless Audio Codec, which shrinks recordings without discarding a single sample. Decoded .flac output is bit-identical to the source, so the format has become the standard for music archiving and high-resolution downloads. For this route the practical draw is genuinely lossless while roughly halving storage and open specification with no royalties anywhere in the chain — balanced against still several times larger than a good lossy encode, which is worth knowing before you commit a large batch.
The usual reason to take .flac audio out of a .mpg file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, dated compression wastes space compared with any modern codec; on the target side, the payoff is genuinely lossless while roughly halving storage, which is exactly what you want for ripping CD collections for permanent archival.
| Aspect | MPEG video (.mpg) | FLAC audio (.flac) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Lossless — every pixel or sample is preserved exactly |
| How it stores data | byte-for-byte the same program stream format standardized in ISO/IEC 11172 and ISO/IEC 13818 | linear prediction followed by Rice coding typically yields files 40 to 60 percent the size of raw PCM |
| Strongest at | working with recordings from PC TV capture cards | ripping CD collections for permanent archival |
| Weak spot | dated compression wastes space compared with any modern codec | still several times larger than a good lossy encode |
| Metadata | nothing beyond the raw stream itself, so titles and descriptions live only in the filename | vorbis comments for tags plus a dedicated PICTURE block for cover art; cue sheets can be embedded for whole-disc rips |

Select .flac in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if FLAC is selectable, the route is real and validated.
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid FLAC file. Outputs keep the original filename with the .flac extension.
Since mpg is container-oriented and flac is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .flac itself requires.
Yes — the .mpg file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
All major browsers decode .flac, Windows 10 and later plus Android play it natively, and virtually every dedicated audio player supports it. The persistent gap is Apple's Music ecosystem, where converting to ALAC delivers the same audio in a supported wrapper.
Much smaller — the video stream is usually 80–95% of a .mpg file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, nothing beyond the raw stream itself, so titles and descriptions live only in the filename; none of it is transmitted anywhere because the file never leaves your browser.
