VOB to BMP Conversion FAQ
How do I convert a VOB file to BMP?
+
Upload your VOB file using the picker above and the converter detects the source type and runs the VOB → BMP pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Why do my extracted frames have horizontal lines through them?
+
Because the source is interlaced. VOB content from the broadcast and DVD era stores two half-height fields per frame, captured a fiftieth of a second apart, and a still pulled straight out shows both woven together as combing on anything that moved. Enable deinterlacing before extraction and each still is built from a single reconstructed progressive frame. VOB is the Video Object container found in the VIDEO_TS folder of every DVD — an MPEG-2 program stream with DVD-specific navigation data added.
Which frame of the VOB do I actually get as a BMP?
+
The one you point at, not just the first. A timestamp picks a single moment out of the VOB; an interval setting walks the whole video and returns one BMP per step, delivered as a ZIP. The default grabs a frame a few seconds in rather than at 00:00, because the opening frame of a video is very often black.
How big will the BMP files be?
+
Larger than you might expect, because BMP keeps every pixel exactly rather than approximating. A 1080p still lands around 2-5 MB and a 4K still around 6-15 MB, so a long extraction run adds up quickly. That is the right trade when the images feed further processing, and the wrong one when they are going straight onto a web page. BMP usually stores completely uncompressed pixel rows with a small header, which is why it is so simple to parse.
Is the VOB to BMP converter free?
+
Yes — basic VOB → BMP conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a VOB file can I convert to BMP?
+
Free accounts: up to 100 MB per VOB file. Premium: typically 1 GB per file, depending on the VOB source type. Very large files are split into chunks server-side when the BMP format allows.
Will conversion change the content of my VOB?
+
Conversion preserves all information that both VOB and BMP can represent. Format-specific features that the BMP format doesn't support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
Can I convert many VOB files to BMP at once?
+
Yes — drop multiple VOB files into the upload zone and they are queued in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the VOB to BMP converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the VOB to BMP converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
Are my VOB files kept private?
+
Yes — uploaded VOB files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
What if the BMP download doesn't start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download, you can re-trigger from the result page without re-uploading the VOB.
