Photopea is a unique free editing application — I’ve never used anything like it. It’s a Photoshop alternative that you just open in your web browser. Both the interface and its feature list will be familiar to anyone who has used Photoshop. While it doesn’t have every feature of Adobe’s flagship photo editor, Photopea isn’t a lightweight editor either. It has enough power and features to keep many users from having to purchase a photo editing software. It’s free and open-source, with some ads that help support its development, but the ads aren’t intrusive. You can upgrade to a premium account for $9 per 30 days to remove ads and support the developer.
