No, I'm not comparing a 230 K PDF to anything. The size of what was once a PDF is irrelevant, I was merely giving some background to the issue. Once the 230 K PNG was opened in Paint.net, any attempts to alter it, or even save it with no changes, caused it to become a 1100 K PNG. Is there an explanation for why this happens and a way to maintain a similar file size without reducing the image quality?

Hello, and thanks in advance for advice. I was attempting to make alterations to a .PDF that was not editable in Acrobat. I exported the .PDF to .PNG format (230 KB, 13200x8400 at 300 pixels/inch). After deleting and rewriting two words, I saved a new .png file and found that the minor change increased the file size to 1100 KB. Finding that unusual, I opened the original .PNG and used 'save as' to create a new file with no changes, and it also ballooned to 1100 KB. Is there an explanation for why a file would substantially increase in size upon saving it in Paint.net when no alterations have been made to canvas size or resolution? Is there a way to maintain a file size similar to the original image without reducing canvas size by a quarter? Thanks again,
