Frequently Asked Questions
How does Gaussian blur work mathematically?
Gaussian blur applies a normal distribution bell curve convolution kernel across neighboring pixels, creating smooth, organic transitions without harsh edges.
Can blurred text or faces be unblurred by someone else?
No. Gaussian blur permanently discards high-frequency pixel details by blending them irreversibly into neighboring colors. Once saved, the original data cannot be reconstructed.
What is the maximum blur radius supported?
You can adjust blur intensity from a subtle 1px softening filter all the way to heavy 50px abstract color washes.
