Save As...

[Bandit12345]

I have been using Paint.net for the past 4 months, 6 hours per day, every day,

to create a photo family album (big family - I know!).

The only drawback I've found it that when using the Save As... option, I am constantly

manually changing the program's default format from .pdn to .png.

I think (in my opinion) that they should add the option to change the Save As... (permanently)

to whatever the user wants.

It may not seem like a big deal, but when you're saving in excess of 490 pages - it makes all the difference!!!

If you flatten the image first, the default filetype for flattened images is .png

The extension adopted is related to data loss. Paint.NET selects the extension which preserves data.

If you image has more than one layer, the extension *.PDN is used as this is the only format which preserves the layer structure and is lossless .

If your image is a single layer, the extension *.PNG is applied. This saves the image losslessly.

Now you understand why pdnnoob's suggestion was to flatten the image (Ctrl + Shift + F). As a single layer image the extension *.PNG will be applied, HOWEVER the resultant file will be a single layer. Useful for the final version of something - less than useful if you wish to re-edit the image. Tip: Always save yourself a master *.PDN copy!
