I like MockoFun because is a free online tool that does pretty much everything. It has a powerful photo editor with smart filters for non-destructive photo editing. The tool has over 800 free online fonts to create awesome text graphics and text effects. You have the possibility to create custom text on path like curved text, heart text, spiral text, etc. You can also create posters, flyers and mockups. The tool has pre-made templates that are both free and premium. One of my favorite feature is the doodler tool that allows you to create vector graphics. The vectorizer tool is also a nice addition and you can turn your photos into vector images easily. MockoFun has lots of elements like photos, shapes, illustrations, PNG cutouts, photo overlays and other useful graphics. You can create awesome designs in just a few minutes.
