Free tool to Create/Edit PNG Images? [closed]

Is there any free tool available for creating and editing PNG Images?

Solution 1:

Paint.NET will create and edit PNGs with gusto. It's an excellent program in many respects. It's free as in beer and speech.

Solution 2:

The GIMP (GNU Image Manipulation Program). It's free, open source and runs on Windows and Linux (and maybe Mac?).

Solution 3:

I use Pixlr - an online photo editor, it has great filters and user friendly interface.

Solution 4:

Inkscape is a vector drawing program that exports PNG images. So, you end up editing SVG documents and exporting them to PNGs. Inkscape is good if you're starting from scratch, but wouldn't be ideal if you just want to edit existing PNGs.

Note--Inkscape is open source and available for free on multiple platforms.
