PicMonkey’s best feature is its ease-of-use compared to more advanced options on our list. It’s straightforward and the UI is friendly and intuitive (so much so that my eight-year-old can handle it in a few short moments), laid out logically and without clutter. Featuring a great collage maker that outshines most other simple photo editors, PicMonkey is accessible to everyone.
It also has all sorts of really useful templates that help speed up your workflow as well as facilitate the creation of headers and banners for blogs, websites, and marketing materials. While PicMonkey can only process one file at a time, it is still a great option for an online photo editor app.
