What is Image Compare Slider?

This tool allows you to easily compare two images by overlaying them and using a slider to alternately display them. It's commonly known as an Image Comparison Slider.

This tool is useful in various scenarios, such as comparing before and after image edits, checking design changes, comparing photo processing effects, and more.

How to Use Image Compare Slider

Select two images you want to compare using the respective input boxes.

The images will be overlaid with a slider. You can move the slider left and right (or up and down) to compare the images.

Features

  • Direction Toggle: Choose between horizontal (left-right) or vertical (up-down) slider orientation
  • Image Details: View detailed information about the images including filename, extension, size, resolution, etc.
  • Fullscreen View: Convenient for comparing images on a larger display

Use Cases

  • Before and after comparisons of web designs
  • Checking photo editing effects
  • Visualizing differences in image processing
  • Comparing landscapes or buildings photographed at different times

Supported Image Extensions

The tool supports basic extensions like .jpeg, .jpg, .png, .gif, as well as .webp and other general image file formats.

Different Image Dimensions

Since the images are overlaid for comparison, it's preferable that both images have the same dimensions (width and height).
If the dimensions differ, the slider may not work as expected.

Image File Size

Currently, there is no file size limit, but processing may become slow or unstable if the images are too large.

The recommended size is under 10MB. Especially when working with high-resolution images, we recommend compressing them to an appropriate size beforehand.

Privacy of Image Information

This tool processes everything in your browser, and your uploaded image data is never sent to any server. You can use it with confidence.

Image Sharing

It is not possible to share the compared images using a shared link.

  • The sharing feature has been highly requested, so we're considering offering it as a separate service 🫡
