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. Text and files are not uploaded. There are no ads, accounts or analytics. History is off by default. You can opt in to local history or manually save comparisons in your browser; do not save sensitive secrets.
