What is Image Comparison Slider?
The Image Comparison Slider is an interactive before/after tool that overlays two images in a single frame with a draggable divider. Move the handle to reveal more of either image at any position, making it effortless to showcase photo edits, design revisions, product upgrades, retouching work, and visual case studies. The tool supports vertical and horizontal orientations, keyboard navigation, and touch dragging, and accepts JPEG, PNG, WebP, GIF, and BMP files up to 10MB. Everything runs locally in your browser — no uploads, no sign-up, no watermarks.
