Upload your MPG video. PDF.to pulls the audio track out, encodes it to FLAC, and gives you a FLAC-only download. The video stream is discarded.
Will the audio in the FLAC match the original MPG quality?
+
If the source audio is already in a codec compatible with FLAC, we stream-copy without re-encoding — bit-identical to the original. Otherwise we re-encode at 192 kbps by default for near-transparent quality.
Yes, within the free size limit. PRO supports much larger MPG files and parallel batch extraction.
Does PDF.to read or store my MPG content?
+
No. The MPG video and the FLAC audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple MPG files?
+
Yes — drop a folder of MPG videos and you will get a ZIP of FLAC files back, one per source video.
Will the FLAC preserve tags and metadata?
+
Title, artist, and album tags are populated from the MPG container metadata when available. You can edit them after extraction with our audio-tag tool.
ตัวแปลงจะทำงานกับ URL ของวิดีโอสตรีมได้หรือไม่?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the MPG legally first, then upload it for FLAC extraction.
Why is the FLAC file much smaller than the MPG video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the FLAC, which is why it can drop from gigabytes to a few megabytes.
