PicMonkey

When compared to more complicated choices on our list, PicMonkey's strongest attribute is its ease of use. It's simple, and the UI is welcoming and easy (so much so that my eight-year-old can handle it in a matter of seconds), put out rationally and without clutter. PicMonkey is easy to use and has a terrific collage builder that outperforms most other simple picture editors.

It also features a plethora of incredibly handy templates that will help you speed up your workflow and create headers and banners for blogs, websites, and marketing materials. While PicMonkey can only handle one file at a time, it is still an excellent choice for an online picture editing program.

PicMonkey, like numerous other items on this list, offers more capabilities concealed behind a paywall. You may still use the 7-day free trial to have access to the new features, but you must choose a paying plan.
