Phixr is an online photo editor that offers a wealth of image-tweaking tools and loads of options for distributing the finished product.
Like Fauxto, Picnik, PXN8, Wiredness and all the rest, Phixr lets you upload, modify, share and save photos. However, you're not limited to uploading from your PC: Phixr can also pull photos from your Flickr, Photobucket, Picasa and other accounts. It can save finished photos to those services as well, along with Costco, DropShots, LiveJournal and others. You can also download photos back to your hard drive.
As for its image-editing tools, Phixr covers all the basics--cropping, brightness, sharpen, etc.--while offering plenty of nifty advanced effects. Everything's clearly identified (via pop-up descriptors) and easy to use. My only complaint is that most changes you make take at least a few seconds to appear; this isn't exactly real-time editing. Still, Phixr is a fun and effective tool, and definitely worth checking out. —Rick Broida
