Recently, when writing a blog on someone else's computer, there was a need to crop and add a watermark to an image, but the computer didn't have the graphic design software I was familiar with. Downloading a full Photoshop would take too much time and the laptop probably wouldn't have enough battery, and it felt inappropriate to install other simple photo editing software on someone else's computer. Some of the less commonly used, non-mainstream software also required time to explore. The situation was not efficient at all. Then I thought of Pixlr, a website that simulates a Photoshop software, which can be opened directly using a browser. Its features and configuration are almost the same as Photoshop, with a Chinese interface and a 0-second start-up time. After uploading the image, editing can be completed quickly, making it a very convenient tool website. It is a must-have for designers who are out and about, traveling at home, or in case of emergency.
