Question 1

How does the photo comparison tool work?

Accepted Answer

Upload a "before" and "after" photo, and the tool creates an interactive slider comparison. You can switch between slider, side-by-side, and stacked layouts, customize labels, and download the result as a high-quality image.

Question 2

Is my photo uploaded to any server?

Accepted Answer

No! All processing happens client-side in your browser using the Canvas API. Your photos never leave your device. 100% private.

Question 3

What can I use this for?

Accepted Answer

Medical practice websites (treatment before/afters), dental transformations, dermatology results, comparing headshot options, portfolio showcases, fitness progress photos, renovation/remodeling results, and more.

Question 4

What image formats are supported?

Accepted Answer

JPG, PNG, and WebP. Both images should ideally be the same dimensions for best results, but the tool will handle different sizes gracefully.

Question 5

Can I embed this on my website?

Accepted Answer

Yes! After creating your comparison, copy the embed code to add an interactive slider directly to your practice website. The embed is self-contained HTML/CSS with no external dependencies.

Question 6

Is it really free?

Accepted Answer

Yes, 100% free with no limits, no watermarks, and no sign-up required. We offer this as a free tool for medical professionals alongside our AI headshot generation service.
