### PCjs Disk Image Formats

PCjs works best with disk images in a **JSON** format, to save conversion time, so that's the only disk image format
you'll find in the PCjs Project.

To convert any of our **JSON** disk images back into an **IMG** file, you can use the [DiskDump API](/api/v1/dump)
with the *format* parameter set to `img` instead of `json`.  For example:

	{{ site.url }}/api/v1/dump?disk=/disks/pc/dos/ibm/2.00/PCDOS200-DISK1.json&format=img

As an added bonus, when browsing the disk library with the PCjs Node web server, links to JSON-encoded disk images
automatically include "onclick" handlers that invoke the API for you.

See **Creating PCjs-Compatible Disk Images** in the [PCjs Documentation](/docs/pcjs/#creating-pcjs-compatible-disk-images)
for more information about supported disks and formats.
