An interesting and versatile online image editor
Photopea is a photo editor that lets users touch up any image and create professionally finished montages. It offers several features, starting with templates, so you can get on with your work, and it supports formats such as CDR, XD, Sketch, XCF, and PSD. It also lets you save your work in PNG, JPG, or SVG and share it directly on social networks.
The user interface is intuitive and will not be a problem for anyone who is used to this type of application. It is configurable, as you can customize the theme or set your language preferences among the more than 20 the app offers. Not even the advertising, which will be present for those who choose the free version, is at all invasive.
