Pixlr is the creator of online, mobile and desktop image tools and utilities. Today we have three applications in our suite: Pixlr Editor, Pixlr Express and Pixlr-o-matic. They are built in Flash and you need to have the Flash plug-in (get flash) to get it to work, however, 98% of all computers have flash so you are probably set. We also provide screengrabbing tools Pixlr Grabber and one click photo sharing imm.io. Pixlr is now part of Autodesk, a global leader in innovative design software and services.
Who needs online tools? The pixlr services is built for both non-professionals and professional users with editing needs such as editing web images to be posted on social networks like Facebook, MySpace, Bebo, or image sites like Flickr, Fotolog, Photobucket etc.
It's also widely used by professionals for fixing images for news sites and blogs etc.
Performance? Since the editors are Flash-based, how they run depends on what kind of computer you have. If it is lagging you can try to shut down other web page that might be running Flash ads or close other software on your computer that is taking a lot of CPU.
