FAQ

How to blur a face in a photo?
Use "Brush Blur" mode. Select brush size (40-60px recommended for faces), adjust intensity, then click and drag over the face area. Apply multiple times for stronger blur.
What's the difference between Blur and Pixelate?
Blur creates a smooth, out-of-focus effect (Gaussian blur). Pixelate/Mosaic creates a blocky, pixelated effect commonly used for censoring. Both can be applied to full image or specific areas.
Can I blur only part of an image?
Yes! Select "Brush Blur" mode, adjust brush size, and paint directly on the areas you want to blur. Everything else stays sharp.
Is my image safe?
100% safe! All processing is client-side in your browser. Your image never leaves your device.
