Frequently Asked Questions
Can it fix a very blurry photo?
It can significantly improve "soft" images by enhancing edge contrast, but it cannot recover details that are completely lost due to severe motion blur.
Does blurring reduce quality?
Blurring intentionally reduces detail. Sharpening increases perceived detail but over-using it may introduce "noise" or grain.

Understanding Blur & Sharpen
This tool uses "Convolution Matrices" (kernels). A kernel is a small matrix of numbers that slides over the image pixels. For blurring, it averages neighboring pixels. For sharpening, it increases the contrast difference between adjacent pixels to make edges pop.
Why Blur & Sharpen Matters
Quickly recover photos that soft-focus missed or create depth-of-field effects by blurring backgrounds (if you crop/mask first). It is a vital utility for quick photo corrections before posting to social media.
Limitations of Blur & Sharpen
While this tool is useful, keep in mind:
- Applies the effect to the *entire* image globally.
- Cannot selectively blur faces or backgrounds (auto-selection coming soon).
- Heavy sharpening can look unnatural.
