An imgsli alternative for image comparisons
imgsli was a go-to site for sharing image comparisons, especially among gamers, modders and AI upscaling fans. If you are looking for somewhere new to post them, here is what DiffSlider offers and how to move over.

Is imgsli down?
When we checked on 5 November 2026, the imgsli.com home page redirected to the website of an Unreal Engine plugin instead of the comparison tool. We could not test whether older comparison links still open; try yours directly, and save any images you still need.
If imgsli is back by the time you read this, it remains a good tool. This page will be updated when we re-check.
What you get with DiffSlider
Up to ten images in one comparison, with any two shown against each other. Four views: a draggable slider, side by side, a toggle (flicker) view, and a pixel-difference heat map that lights up everything that changed. Every view zooms to 1600% with both images panning together, so you can compare individual pixels of a texture or an upscale.
Images are stored exactly as uploaded, without recompression. Each comparison gets a permanent link, an iframe embed code, and Markdown, HTML and BBCode snippets for GitHub, Reddit, Nexus Mods and forums. With a free account you can see how many people viewed it, how many interacted, which countries they came from and which sites embed it.
How to move your comparisons
If your old links still load, open each comparison and save the original images (not screenshots, which are resized and recompressed). Then drop them into the DiffSlider tool in the same order, use the same labels, and publish. With a free account you can give the new comparison a readable link such as /c/my-texture-pack.
Update the links in your mod pages, READMEs and forum posts. For posts you can no longer edit, add a reply with the new link.
Questions
Is DiffSlider free?
Yes. Making, sharing, embedding and view statistics are free. An optional Pro plan removes ads and watermarks and raises upload limits.
Can I compare more than two images?
Yes, up to ten per comparison. Visitors can switch which two are compared.
Are my images compressed?
No. Files are served exactly as uploaded, so pixel-level comparisons stay accurate.
