Pixlr

Pixlr is a free online photo editor that does not require account creation, just download the app and start editing. This app can instantly adjust the color of your photo in one easy click using Auto Fix. Pixlr also can adjust the tone of the photo with overlays – amplify the tone, cool it down, or add surreal shades. 

It has tools to remove blemishes, red-eye, smoothen skin, or whiten teeth with simple tools. You can also create photo effects using stylize (pencil sketch, poster, watercolor, and more) and keeping things fresh with their growing release of additional effects, overlays, and border packs. Lastly, finish off your editing process with the right border.
