Pixlr

Pixlr is one of many online browser-based photo and image manipulation services. It stands out as the fastest and most flexible. Pixlr has three modes: 'express', 'advanced' and 'playful'. The 'advanced' mode can perform the same kind of alterations to an image as Photoshop and GIMP, and the layout is almost identical. Express mode is very fast and intuitive, and is suitable for first-time users. The 'playful' mode, which is also available as a phone app, allows you to easily add flashy or vintage effects and backgrounds to your pictures.
