Why convert IFO to ISO?
An IFO file alone contains only DVD navigation data and is not usable by itself, but when the entire VIDEO_TS folder is imaged to .iso, the result is a portable single file that any DVD player or virtual drive software can mount with full menus, chapters, and audio/subtitle tracks intact.
How to convert IFO to ISO
ImgBurn FREE
Choose Create image file from files/folders, select the VIDEO_TS folder as the source, set the filesystem to ISO9660 + UDF in the Advanced tab, and click Build. The resulting .iso contains all IFO, VOB, and BUP files.
hdiutil FREE
Run hdiutil makehybrid -o movie.iso /path/to/folder -iso -udf in Terminal, pointing the path at the folder containing VIDEO_TS. Mount the result in Finder to verify menus work.

Open .ISO details →Quality & what to watch
- The IFO is included in the ISO as navigation data, not converted; the VOB files supply the actual video.
- UDF filesystem is required for DVD-Video compliance - building with ISO9660 only may cause players to reject the image.
- A dual-layer DVD source can produce an ISO up to approximately 8.5 GB.
