Nov 5th, 2015 Pixlr image editor releases its version 3.0
Pixlr Desktop organizes all the available effects into category trees you can navigate easily. The first layer of tools is composed of graphic effects, airbrushing, overlays, borders, styles, stickers, and text, all divided into subcategories.
All these effects can be stacked, meaning in just a few steps you can apply a frame, remove red-eye, blur noise in the photo, and add post-production brightness with professional results. The tool is completely free, and just by creating an account on Pixlr you can get instant access to many more effects that are also free.
There's also a paid Pro version with a monthly subscription, which adds many additional features like crop, editing with brushes, and other effects that bring it closer to multipurpose suites like Photoshop or GIMP.
