Pixlr provides a free, cloud-based photo editor than allows you to quickly create and share simple graphics and to edit photos. Sorry, but, "it's free", is the best I can do. Oh, there's also a Chrome app, which seems superfluous.
To be honest, I have a hard time understanding for whom this product would be a good fit. It's free, sure, but pirating the big apps like Photoshop seems so rampant while at the same time on the other end amazing and inexpensive tools like Affinity Photo (and Designer), both of which I paid for, use, and highly recommend, are easily available for the big platforms, I can't think of a single reason to use this other than to tinker with what seems mostly like an experiment for no-longer-cutting-edge web/interactive technologies.
No one who cares about typography, which is to say any serious designer, would be even remotely interested in using Pixlr. I have yet to be able to get Pixler to store my uploaded fonts from session to session, for example. The free fonts are inadequate, to say the least.
If you want to quickly apply trendy or useful filters, there are better solutions, such as Lightroom or VSCO and both have mobile apps.
Also, it's written in Flash, ugh, so how much longer is it going to stick around anyway?
