Below lists several tools that allow you to edit and/or create beautiful images for blog posts, infographics, presentations, and even Facebook posts. All of the below are FREE to use, but some may offer pro plans for more or better options. Please do your research before signing up.

Affinity Photo – Adobe Photoshop Alternative
Affinity Designer – Adobe Illustrator Alternative
Adobe Creative Cloud – PhotoShop / Illustrator / InDesign + More
