Frequently Asked Questions
What is Gaussian blur?
Gaussian blur softens an image by averaging pixel values using a bell-shaped curve, smoothing details and reducing noise for a natural-looking effect.
Is my image uploaded to a server?
No. All processing happens locally in your browser using HTML5 Canvas. Your image never leaves your device, ensuring complete privacy.
What image formats are supported?
You can upload JPG, PNG, and WebP images. The blurred result can be downloaded in the same format as the original.
Can I adjust the blur strength?
Yes. A slider lets you control blur radius from 0px to 20px in 0.5px increments, with a live preview of the result.
