Frequently Asked Questions
What types of color blindness are simulated?
The tool simulates protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind), and achromatopsia (total color blindness).
Why is this important for design?
About 8% of men and 0.5% of women have some form of color vision deficiency. Testing ensures your designs are accessible.
Can I use this for web design testing?
Yes. Upload screenshots of your website or UI designs to check how they appear to color-blind users.

We offer 23 image tools including resize, compress, crop, flip, convert formats, watermark, background removal, color picker, QR code generator, and more — all browser-based.
Are these image tools free to use?
Yes. Every image tool is completely free with no watermarks, no sign-up, no usage limits, and no file size restrictions.
Is my image data private?
All image processing happens entirely in your browser. Your images are never uploaded to any external server, ensuring complete privacy for personal and professional photos.
What image formats are supported?
