5 Best Free Before And After Slider Widgets for Websites in 2022

Like using a customer testimonials slider widget on your site helps in many ways to your business, so does a before and after slider widget.

Before and after slider widgets allow you to represent key differences of a service, place, or product after making a change visually.

But how would you add an HTML before and after slider to a website?

In this article, you will find 5 best before-after slider widgets for websites to use for free.

Why should you use before after slider widgets?

  • Boost sales – Address the inner eagerness of potential customers by showcasing how using your product can get them what they desire with convincing images.
  • Prove your offers are good value for money – Showcase how your products/services could make an obvious, impactful, and significant change to their bottom line.
  • Increase engagement level – Like FAQ widgets on a website help increase engagement, so does a before and after widget on a website.

Where can you use before and after siders?

  • Your online shopping pages – Do you sell physical products? Highlight how your product will impact on user’s life with and without using it with a before and after image slider.
  • Your service pages – Be a construction work, decoration gig, photo editing service, online ads campaign management, SEO gigs, or any kind of digital work, utilize before and after photo slider widgets with captions to emphasize how your services are better after previous clients used them.
  • Use as a substitute for testimonial sliders – Suppose you run a digital marketing agency. In that case, apart from embedding Google reviews on a website, you can use a before and after HTML widget to showcase ROI and growth reports previous (or existing) customers achieved after using your services. You can use trusted image sources such as Google Analytics, Google Search Console, Shopify, Stripe, Semrush, and Ahrefs.

Top 5 things to consider when using a before and after slider on a website

  1. Utilize the right image dimensions – In a before and after photo slider, you have to use two images of equal size. Make sure both of them are correct dimension-wise & image-ratio-wise and cropped to adjust to the right size of the widget. You may want to use an aspect ratio calculator like this to make images appropriate for the before and after graphic slider.
  2. Compress images – Reduce file sizes by optimizing using an image compressor such as ShortPixel, or TinyPNG.
  3. Minimize the impact on page speed – Most of these before and after slider generators come with an external JavaScript that will probably load external assets such as fonts and icons dynamically. So, without loading them prominently, you can use the defer or async parameters to load the script while minimizing the impact on page loading time. To optimize tags, use a script manager such as Google Tag Manager or Zaraz by Cloudflare. Also, load the script only where the widget is placed.
  4. Utilize captions – Text description or the caption section allows you to describe the image comparison and link to relevant pages.
  5. Split test – Use different image combinations, widget placements, captions, dividers, image ratios, divider directions so on, and identify the highest performer to achieve a better yield from a before and after image slider.
