Frequently Asked Questions
Do the images need to be the same size?
No, but best results come from images with similar dimensions and aspect ratios. The tool automatically aligns them. If images have different proportions, the comparison will still work but may show letterboxing on one side.
Is there a file size limit?
We recommend images under 10MB each for best performance. The slider comparison renders entirely in your browser using CSS and HTML.
Can I embed this on my website?
The saved PNG is a static export. For interactive sliders on your own website, you can use CSS-only or JavaScript implementations such as the Juxtapose library or simple CSS clip-path techniques.
