What are the best use cases for a beforeafter image slider online free?

It's excellent for photographers showing photo editing results (e.g., retouching, color correction), web designers demonstrating website redesigns, artists showcasing digital painting progress, historical photo restoration comparisons, or any project where a visual 'before vs. after' is impactful.

Do the two images need to be the exact same size for the image comparison slider online?

For the best comparison, it's highly recommended that both images have the exact same dimensions. The slider will attempt to overlay them. If they are different sizes, the comparison might not align perfectly, and one image might be scaled or cropped by the component to fit the container of the other.

Can I embed this image compare slider online on my website?

This specific tool is an online utility for you to create and view the comparison. It does not directly provide an embed code. However, understanding how it works can inspire you to use similar JavaScript libraries (like `react-compare-slider` which this tool uses) if you're developing your own website and need free slider images for websites.

Is this free image comparison tool secure for sensitive images?

Yes. All image loading and the comparison slider functionality happen entirely within your web browser. Your images are not uploaded to any external server, ensuring your privacy and data security.

Can I change the slider's appearance beyond color and thickness?

This tool offers basic customization for the handle's color and thickness. More advanced styling (like custom handle shapes or icons) would typically require direct coding with the underlying library or custom CSS, which is beyond the scope of this simple online tool.
