Frequently Asked Questions

What is the difference between Gaussian and Mosaic blur?
Gaussian blur creates a smooth, soft blurring effect, while Mosaic divides the area into pixel blocks for a pixelated look.
Does blur affect the rest of the image quality?
No. Unblurred areas remain at original quality. The image downloads as PNG with no compression loss.
Are files uploaded to a server?
No. All processing happens 100% in your browser. No images are sent to any external server.
Can I undo blur strokes?
Yes, use the Undo button to restore the previous state. Up to 20 undo steps are supported.
