PicMonkey is a free web-based photo editor that you can use without signing up. Once you upload your photo, it keeps things simple by showing the "Basic Edits" which are the seven tools you will most likely need to use.
- Auto Adjust
PicMonkey has many more features if you click one of the gray icons to the left of the tool list. The "Touch Up" tools let you fix blemishes, erase wrinkles, add blush or spray on a tan with a click.
Even if all it had was the easy to use crop and resize tools, I'd be very happy with PicMonkey. I can't believe how hard it was to find a program that did these two functions easily and well. PicMonkey does everything I want an online picture editor to do and more!
