Done! I've created a responsive before/after image comparison slider with your uploaded photos. It features a draggable handle divider, works with mouse and touch, and uses your brand's primary color for the handle accent.

What Is a Before & After Slider?

A before and after slider is an interactive element that lets visitors drag a divider across two overlapping images to reveal changes. It's commonly used by photographers to show editing results, by contractors to display renovation progress, by dermatologists to present treatment outcomes, and by designers to compare visual options. Unlike placing two images side by side — which wastes space and loses impact on small screens — a slider shows both versions at full size within a single compact frame. Visitors actively engage with the content rather than passively scrolling past it, making it one of the most effective ways to present any visual transformation on the web.

Why Add a Before & After Slider to Your Website?

Turn static visuals into interactive proof that converts visitors into customers

Prove Results Visually

Nothing builds trust like showing the actual before and after. Let your work speak for itself — no written testimonial is as persuasive as seeing the transformation firsthand.

Boost Engagement & Time on Page

Interactive sliders invite visitors to stop scrolling and start exploring. That extra engagement keeps people on your page longer — a signal search engines love.

Replace Clunky Side-by-Side Layouts

Two images stacked or placed side-by-side waste space and lose impact on mobile screens. A slider shows both images at full size, in the same footprint, on any device.

Everything You Need in a Before & After Slider

Powerful features wrapped in a simple, no-code builder

Drag, Hover, or Click to Compare

Your slider supports multiple interaction styles. The classic drag mode lets people scrub back and forth at their own pace. Hover mode reveals the comparison as the cursor moves — great for quick previews. Click mode toggles between the two images instantly. Just tell the AI which interaction you want.

Slide Vertical or Horizontal

Not every comparison works left-to-right. Ask for vertical sliding and the AI builds a top-to-bottom reveal — perfect for full-length portraits, tall product shots, or architectural images. Both directions are fully responsive and work on every device.

Custom Labels & Branding

The default "Before" and "After" labels work for most cases, but you can change them to anything — "January / December", "Original / Edited", "Without / With Treatment". Just tell the AI what you want — match your brand colors, reposition labels, or hide them entirely for a clean minimal look. No digging through settings panels.

Frequently Asked Questions

Everything you need to know about before & after sliders

What is a before and after slider?

A before and after slider is an interactive website element that lets visitors drag a divider across two overlapping images to reveal changes. It's the standard way to present visual transformations — renovations, photo retouching, product redesigns, medical results, and more — in an engaging, space-efficient format.

How do visitors interact with the slider?

Visitors can drag the central divider left and right (or up and down for vertical sliders) to reveal more or less of each image. On desktop it responds to mouse dragging, and on mobile it works with touch gestures. You can also configure it for hover or click interaction modes.

Can I use both vertical and horizontal sliding?

Yes. MightyWidgets supports both horizontal (left-right) and vertical (top-bottom) slider directions. Choose whichever orientation best suits your images — horizontal works well for landscape shots, while vertical is great for full-length portraits or tall product images.

What image formats are supported?

You can use JPG, PNG, WebP, and GIF images. For best results, use two images with the same dimensions. The widget automatically handles responsive scaling so your images look sharp on every screen size.

Will a before and after slider slow down my website?

No. MightyWidgets loads asynchronously so it never blocks your page from rendering. The widget code is lightweight and served from a global CDN. Your page loads first, then the slider appears — visitors never experience a delay.

How do I add a before and after slider to my website?

Sign up for a free MightyWidgets account and describe the slider you want in plain English. Upload your before and after images, and the AI builds the widget for you. Ask for any adjustments — different labels, colors, interaction style — until it looks exactly right, then publish. You'll get a single line of embed code to paste into any page on your site.

Does the slider work on mobile devices?

Absolutely. The slider is fully responsive and touch-optimized. It adapts to any screen size automatically, and the drag interaction works just as smoothly on phones and tablets as it does on desktop.

Is MightyWidgets free to use?
