blickbox Posted May 26, 2016 Share Posted May 26, 2016 I work with very large photos, and need to add shapes/comments etc. to it. It's easier to add these shapes as a seperate layer, since it's easy to edit them later. Problem is when I save the photo, it's saved as .PDN, and the file size is VERY large (often 300MB +) since I guess the format is lossless. The source file is usually a heavily compressed (75) JPG at around 15MB. Is there any way to work with multilayer images, and have it saved in a compressed format?

dipstick Posted May 26, 2016 Share Posted May 26, 2016 PDN format is already compressed. 300MB is not very large, it would easily exceed 1GB were it uncompressed. If you don't have a lot of HDD space, use an external HDD or USB thumbdrive to store your project files. Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted May 26, 2016 Share Posted May 26, 2016 dipstick, PDN and PNG are losslessly compressed. JPEG is lossy compression. There's a major difference Both are compression, but have different goals. blickbox, You cannot save a PDN with lossy compression.
