The free version allows users to create or edit images/graphics using tools similar to those found in other programs such as Photoshop, Fireworks, and Gimp. Users can save the images to their computer or to SumoPaint (with account) as a SUMO, .png, or .jpg file.
To help you get started, SumoPaint has a help feature allowing users to select the tool they want to know more about and often times see a video that shows how that tool works. You can also find some tutorial videos on YouTube.
Whether you are trying to make minor edits like removing red-eye from a photo or creating graphics from scratch, SumoPaint can help.
