Jim Williams Posted February 22, 2020 Share Posted February 22, 2020 Windows File Manager says a file is 366 KB. When I go to Resize, it says the image size is 24 MB. Doesn't the Resize option show the actual size or am I missing something? Quote Link to comment Share on other sites More sharing options...
toe_head2001 Posted February 22, 2020 Share Posted February 22, 2020 24 MB would be the uncompressed size. When you save an image as, for example, a PNG, it uses lossless compression; resulting in a smaller file size. Quote (September 25th, 2023) Sorry about any broken images in my posts.

Jim Williams Posted February 22, 2020 Author Share Posted February 22, 2020 This has me even more confused. If file manager is showing a compressed file size of 366 KB, is Paint.net loading an uncompressed size of 24 MB? Quote Link to comment Share on other sites More sharing options...
toe_head2001 Posted February 22, 2020 Share Posted February 22, 2020 Yes. When a file is opened in Paint.NET (or any other image program), it is decompressed.

HyReZ Posted February 22, 2020 Share Posted February 22, 2020 (edited) Greetings, Here is an analogy to think about that may ease your confusion. If you take program and place it into a compressed archive such as a zip file, its Properties will show a reduced file size. When the zip is uncompressed it is restored to original file size. Try this: Download this .jpg test pattern image onto your computer and then use Properties to examine its file size.https://www.wallpaperflare.com/static/373/727/729/tv-abstract-test-patterns-test-wallpaper.jpgNow open the image in Windows Paint and save it as a .bmp file and check its Properties.As a .jpg it is compressed to 41.9 kb, but as a decompressed .bmp it is now 8.48 MB.BTW:Both the .jpg and the .bmp will yield a Color Count of 937 due to tints, tones, and shades created by the process of anti-aliasing.
