How Diferencia de Imagen Works
An Image Diff Tool is a visual regression utility used to spot differences between two pictures. This tool is essential for QA engineers, designers, and frontend developers verifying pixel-perfect implementations, checking for compression artifacts, and detecting unintended layout shifts.
The Comparison Modes
- Difference (XOR): Highlights only the changing pixels in high-contrast color.
- Slider / Swipe: Lets you manually drag a divider over the images to see the Before/After state interractively.
- On/Off Toggle: Rapidly switches between images to make changes "flash" (best for spotting subtle shifts).
