Drop two images to compare them four ways: side by side, with a slider you drag across, as an overlay with adjustable opacity, or as a difference map that marks every changed pixel in magenta and tells you what share of the image changed.
It is useful for checking screenshots, design revisions and visual regressions. Images are opened in your browser and never uploaded.
PNG, JPEG, GIF, WebP, AVIF, BMP, SVG and ICO, or anything else your browser can display.
They are lined up at the top-left corner, and the size difference is shown above the images.
Not to compare it. The comparison runs entirely in your browser, and the text you paste and the files you open are never sent to a server for that. There are no ads, no accounts and no analytics. If you copy a share link, the text is packed into the link itself, in the part after the # that is never sent to a server. Your history and saves stay in your browser.
