Quick Tool Overview

The Before After Slider Maker produces both forms of comparison: a static split image that works anywhere an image works, and a self-contained HTML file with a draggable divider, images embedded and no external dependencies. Labels, divider style and starting position are adjustable in both.

About the Before After Slider Maker

Before-and-after comparisons are how retouching, renovations and restorations are shown, and there are two ways to present one: as a static split, or as a draggable slider.

Both come out of this page. The static version puts the two images either side of a divider at a position you choose, which works anywhere an image works — email, print, a PDF. The interactive version is a single self-contained HTML file with the images embedded and no external dependencies, so it can be dropped into any page or opened on its own. Labels, divider style and starting position are adjustable in both.

Key features of the Before After Slider Maker

Static or interactive

A PNG for email, print and PDFs; a draggable slider for a web page.

Self-contained embed

One HTML file with both images inlined and no CDN, so it works offline and cannot break later.

Labels on both sides

Before and after captions drawn onto the image, which most comparison tools leave you to add yourself.

Adjustable start position

Open the divider over the most changed area so the difference is obvious before anyone drags anything.

Handles size mismatches

Different-sized images are fitted to a common frame, with the page explaining why matching framing matters.

How to use the Before After Slider Maker

  1. 1

    Add the before image

    The two images should be the same size and framing for the comparison to work.

  2. 2

    Add the after image

    Mismatched sizes are fitted, but the effect is much weaker.

  3. 3

    Set the divider

    Choose the split position, the divider style and the labels.

  4. 4

    Take the image or the embed

    A static PNG, or a self-contained HTML file with the slider built in.

Frequently asked questions

They should be, and ideally the same framing too. Different sizes are fitted to a common frame, but if the subject moves between them the comparison stops reading.
