Photopea is an advanced image editor that can handle raster and vector graphics. You can use it for simple image processing, such as resizing images, as well as complex tasks like designing web pages, creating illustrations, and editing photos. It supports common image formats and can be used for free on the web without the need to download any software or even log in, with Simplified Chinese support.
Photopea can run offline, just like Sketch or Photoshop. It does not upload any of your files to the internet. You can open Photopea.com, disconnect from the internet, and use it completely offline.
