The header tells us which format and size to expect.

Generate the ISO

Your file size determines the price before processing starts.

Save your file

Download the ISO before closing the page. Allow space for the temporary file and download.

Using CHD to ISO

CHD to ISO decompresses a supported optical image into an uncompressed disc file. A CHD can also represent a hard disk or depend on another parent image, so its extension alone is not enough to identify a suitable input. The converter reads the version, geometry and metadata before proceeding.

Which CHD to ISO layouts work?

CHD to ISO accepts standalone version five DVD images and supported single data track CDs. For a CD, the data track must use Mode 1 or Mode 2 Form 1 without gaps. Audio and mixed track discs need a track aware format that retains their recording layout and additional streams.

Working with larger outputs

CHD to ISO can produce an output much larger than its compressed source. Keep this page open, provide storage for the temporary ISO and download, and retain the original CHD. If a data check fails, use a complete source image and confirm that it does not require a parent file.
