What image formats does Image Compare support?

JPG, PNG, and WebP formats are supported. The two images you compare can be in different formats.

Can I compare images with different dimensions?

Yes, the tool automatically scales both images to the same dimensions for comparison. For the most accurate results, use images with similar resolutions.

Are my images sent to a server?

No. All processing happens locally in your browser. Your files are never transmitted to any server.

How is the difference percentage calculated?

RGB pixel values are compared channel by channel. The percentage reflects how many pixels differ beyond a set threshold relative to the total pixel count.

Does the slider mode work on touchscreens?

Yes, the slider responds to touch gestures on mobile and tablet devices without any extra setup.

Can I compare very large image files?

Yes, though processing time may increase for very high-resolution images depending on your device. Files up to 20 megapixels work smoothly in most modern browsers.

Can I share the comparison report with others?

You can download the report as a PNG or PDF and share it however you like. A shareable link feature is not currently available.
