What is I built a browser?
PicDiff is a browser-based tool for spotting differences between two images side by side. You upload or paste two images, and the tool highlights variations at the pixel level, making it easy to identify subtle changes that might be hard to catch with the naked eye. It's designed for anyone who needs to compare visuals quickly: designers checking iterations, QA testers validating screenshots, developers reviewing AI-generated outputs, or content creators verifying before-and-after edits. The results can be shared via a link, so you don't need to send large image files back and forth.
