AC3 to VOB Conversion FAQ
Why would I convert AC3 audio to a VOB video?
+
A VOB video plays everywhere a raw AC3 sometimes will not — most notably on video-only platforms and social feeds that require a video container. It is the standard way to publish a podcast, song, or mix as a shareable VOB.
Can I batch-convert many AC3 files to VOB?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the AC3 to VOB conversion free?
+
Yes, within the free size limit. PRO unlocks much larger AC3 uploads, longer durations, and parallel jobs.
How long can the AC3 be?
+
Full-length albums and multi-hour AC3 recordings convert fine. Because the picture is static, even a long VOB stays modest in size relative to a filmed video of the same length.
Will the VOB play on YouTube, Instagram, and TikTok?
+
Yes. PDF.to encodes the VOB with a widely supported codec and pixel format, so the resulting video uploads cleanly to the major platforms that reject bare AC3 audio.
Are my AC3 files private during conversion?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded AC3 and the resulting VOB are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
