What is jas file?

File type category:
Bitmap image file

Date updated: July 14, 2025

The jas file extension is associated with Corel Paint Shop Pro, an advanced photo-editing software, developed and sold by Corel Corporation.

The *.jas files contain bitmap images.

The .jas format files were designed to create the smallest possible image files for 24 bits per pixel color images and 8 bits per pixel gray scaled images. Jas uses a discrete cosine transformation to alter the image data and then compress that data. This process results in a substantial reduction of the file size when the image is saved to the disk. This method is referred to as "lossy": saving and retrieving an image using the jas file format will result in some loss of image data. The amount of loss is dependent on the compression level that you have selected in your application. By using the lowest possible value for the file compression you will have the least amount of loss.
