FLV to OGG Conversion FAQ
How do I extract audio from a FLV video as OGG?
+
Upload your FLV video. PDF.to pulls the audio track out, encodes it to OGG, and gives you a OGG-only download. The video stream is discarded.
Will the audio in the OGG match the original FLV quality?
+
If the source audio is already in a codec compatible with OGG, we stream-copy without re-encoding — bit-identical to the original. Otherwise we re-encode at 192 kbps by default for near-transparent quality.
What bitrate is the OGG output?
+
192 kbps by default. The options panel exposes 96, 128, 192, 256, and 320 kbps — pick higher for music, lower for voice.
Can I extract only part of the FLV as OGG?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes OGG.
Does the converter handle FLV files with multiple audio tracks?
+
Yes. If your FLV has several language or commentary tracks, you can pick which one(s) to extract as OGG in the options panel.
Will the OGG output have the same sample rate as the source?
+
Yes by default. We do not resample unless you explicitly request it. 48 kHz is preserved from movie sources, 44.1 kHz from music sources.
Is the FLV to OGG extraction free?
+
Yes for files under 100 MB. PRO supports larger FLV files (5 GB) and parallel batch extraction.
Does PDF.to read or store my FLV content?
+
No. The FLV video and the OGG audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple FLV files?
+
Yes — drop a folder of FLV videos and you will get a ZIP of OGG files back, one per source video.
Will the OGG preserve tags and metadata?
+
Title, artist, and album tags are populated from the FLV container metadata when available. You can edit them after extraction with our audio-tag tool.
Does the converter work on streaming video URLs?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the FLV legally first, then upload it for OGG extraction.
Why is the OGG file much smaller than the FLV video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the OGG, which is why it can drop from gigabytes to a few megabytes.
