Saikoupathic Posted September 13, 2023 Share Posted September 13, 2023 Recently I finished a 4-5 hour project for myself and saved it as a PNG. But when I tried to reopen it, it doesn't work, nor does it work on photo app. Both paint.net and photos are updated, but later, its now a pdn image, still doesn't open, it gives this error below. If anyone can tell me what happened, I'd really appreciate it, same for fixes too.

Ego Eram Reputo Posted September 13, 2023 Share Posted September 13, 2023 Odds are the file extension is not aligned to the type of encoding used. Try this plugin to see if it will identify the file type.

But when I tried to reopen it, it doesn't work ... but later, its now a pdn image, still doesn't open As written, your question does not make sense. How did your png file later become a pdn file? There is some information about the steps you carried out that you have not told us. As EER hints, you have most likely given the file the wrong file type, probably by typing it when saving or when renaming the file. Quote Link to comment Share on other sites More sharing options...
Lemonade Posted September 13, 2023 Share Posted September 13, 2023 From what I understand about paint.net, if you save as .png, then add new layer to your document, next save (CTRL+S) will open a save dialog and set .pdn as default filetype.

otuncelli Posted September 13, 2023 Share Posted September 13, 2023 (edited) It sounds like you saved your work in PDN format (or another format) but with PNG extension (or changed it to PNG afterwards.) Try changing the extension to PDN then open. Paint.NET chooses the correct decoder based on the file extension. PNG is giving the wrong hint in this case.
