Frequently Asked Questions (FAQ)

Is my image uploaded to your servers?

No! This tool runs entirely in your web browser utilizing client-side JavaScript. Your images are never uploaded, stored, or processed on any remote server, ensuring 100% data privacy and security.

What is the difference between Gaussian Blur and Box Blur?

Gaussian Blur provides a smooth, soft, and natural blurring effect, mimicking a camera's out-of-focus lens by using a bell-curve algorithm. Box blur uniformly averages a perfect square of adjacent pixels, resulting in a slightly harsher, more structural blur often used for special visual effects or heavy pixelation.

How does the "Blur edges only" feature work?

It applies a dynamic radial mask over the blurred layer that keeps the exact center of your photograph in perfect focus while gradually transitioning to a full blur towards the edges. This creates an exaggerated depth-of-field often referred to as a tilt-shift effect, which emphasizes your main subject.
