If you’re not going to buy a license of Adobe Photoshop to edit your images, you’ll appreciate Pixlr Editor, a new software from Autodesk (the maker of AutoCAD, Revit and 3ds Max, for instance) available in a free web version to the following address:

http://apps.pixlr.com/editor/

Pixlr Editor is a software that allows you to:

• open images from a web URL or your computer;
• save images in different formats (PNG, JPG, etc …);
• resize, crop and rotate images;
• create multiple layers (like in Adobe products), merge and rasterize them, create layer masks;
• adjust brightness, contrast, hue, saturation and apply other color effects to the image;
• apply filters to the image (noise, pixelate, vignette, emboss, engrave, etc …).

The web application is available in several languages ​​and is developed in Flash, so you must ensure that your browser supports the famous Adobe plugin (you can find it here: https://get.adobe.com/flashplayer/).

The application is also available for Android and iOS to the following address:

There are also other Autodesk similar products, like Pixlr Express, for quick photo editing, and Pixlr O-Matic, for effects, overlays and borders.
