Upload your AVI video. PDF.to pulls the audio track out, encodes it to AAC, and gives you a AAC-only download. The video stream is discarded.
Will the audio in the AAC match the original AVI quality?
+
If the source audio is already in a codec compatible with AAC, 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 AAC output?
+
Подразумевано 192 кб/ с. Опције разоткривају 96, 128, 192, 256, и 320 кб/ с — изаберите више за музику, ниже за глас.
Can I extract only part of the AVI as AAC?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes AAC.
Does the converter handle AVI files with multiple audio tracks?
+
Yes. If your AVI has several language or commentary tracks, you can pick which one(s) to extract as AAC in the options panel.
Will the AAC output have the same sample rate as the source?
+
Да, подразум› ијевано. Не узоркујемо поново осим ако је изричито не затражите. 48 кХз је сачувано из филмских извора, 44,1 кХз из музичких извора.
Is the AVI to AAC extraction free?
+
Yes, within the free size limit. PRO supports much larger AVI files and parallel batch extraction.
Does PDF.to read or store my AVI content?
+
No. The AVI video and the AAC audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple AVI files?
+
Yes — drop a folder of AVI videos and you will get a ZIP of AAC files back, one per source video.
Will the AAC preserve tags and metadata?
+
Title, artist, and album tags are populated from the AVI container metadata when available. You can edit them after extraction with our audio-tag tool.
Да ли претварач ради на преносу видео УРЛ‐ ова?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the AVI legally first, then upload it for AAC extraction.
Why is the AAC file much smaller than the AVI video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the AAC, which is why it can drop from gigabytes to a few megabytes.
