Best Photo Editing Software In 2020. You can use overlays and textures to superimpose two images together, add a vintage look to your images, or separate the RGB channels to create an abstract effect. And, with Pinch Zoom, it’s easy to view fine details and make precise edits. Pixlr is the right photo editor app for everyone; it has all the tools that a user might need. It has over 2 million combinations of free effects, overlays, and filters. You can create photo collages with various layouts, backgrounds, and spacing options. As its name suggests, Adobe Photoshop Express Editor is a trimmed-down, browser-based version of the company's world-leading photo editing software. Once you finish editing your photo, you can save it to a grid and start to edit others, helping you create a cohesive photo grid for social media. Perhaps surprisingly, it features a more extensive toolkit than the downloadable Photoshop Express app, but it only supports images in JPG format that are below 16MB.
