Should you convert OGV to FLAC?
Yes, when you only need the sound: a song from a music video, the audio of a lecture, or a voice recording to transcribe. The picture is left out and the soundtrack is saved as FLAC.
OGV is open-source Theora video in an Ogg container; FLAC is lossless audio at roughly half the size of WAV. Use FLAC to archive music and recordings you may want to convert again later.

How to convert OGV to FLAC
- 01
Add your OGV
Drop your OGV video onto the box, or click to choose it. It is read from your disk and stays there.
- 02
Check the settings
The output is already set to FLAC. Change the bitrate if you want to; the defaults suit most files.
- 03
Save the FLAC
Press convert and save the FLAC. Several files come back together as a ZIP.
What changes when OGV becomes FLAC
FLAC is lossless, the soundtrack usually isn’t
The audio inside an OGV is almost always compressed already, usually as Vorbis. FLAC preserves it exactly but makes a much larger file without sounding better. Choose it for editing software; choose MP3 or M4A for listening.
Video files without sound
Screen recordings and some exported clips have no audio track at all. The file is checked as soon as you add it, and you’ll be told before converting if there’s nothing to extract.
This page is put together from our notes on each format, choosing only what is true of OGV and FLAC, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
Uploading a whole video to keep only its sound wastes time and data, and hands over the footage too. The audio track is read and saved right here, and the file never leaves your device.
How to check for yourselfWorth knowing
- About the OGV. Theora needs a much higher bitrate than H.264 for the same picture, so an OGV of the same size looks noticeably worse.
- About the FLAC. FLAC made from an MP3 is lossless only in name: it perfectly preserves an already lossy recording, at five times the size.
- AVI, WMV, FLV and other older formats use the FFmpeg engine, a one-time 31 MB download.
Questions
Does extracting FLAC from an OGV lose quality?
No. FLAC stores the soundtrack exactly as decoded, although it can’t improve on the compression already in the video.
Can I get the audio from only part of the video?
Yes. Set a start and end time before converting, and only that section is saved as FLAC.
