### PCx86 Disk Image Formats

PCx86 works best with disk images in a **JSON** format, to save conversion time, so that's the
only disk format you'll find in the [PCjs Project](https://github.com/jeffpar/pcjs).

There are several ways you can convert a PCjs **JSON** disk image back into a binary **IMG** file:

- Load the desired disk into a PCjs machine and click the **Save** button
- Use the [DiskDump API](/api/v1/dump) (available only in the [PCjs Node Web Server](/server.js))

When using the [DiskDump API](/api/v1/dump), set the *format* parameter set to `img` instead of `json`.
For example:

	{{ site.url }}/api/v1/dump?disk=/disks/pcx86/dos/ibm/2.00/PCDOS200-DISK1.json&format=img

The [PCjs Node Web Server](/server.js) also generates "onclick" handlers for links to **JSON** disk
images that automatically invoke the API for you.

See [Creating PCx86-Compatible Disk Images](/docs/pcx86/#creating-pcx86-compatible-disk-images)
in the [PCx86 Documentation](/docs/pcx86/) for more information about supported disks and formats.
