❓ Frequently Asked Questions
Everything you need to know about image mosaic effects
How does the mosaic effect work?
The mosaic effect works by dividing the selected area into small blocks and replacing each block with the average color of that area. This creates a pixelated effect that obscures details while maintaining the general shape and color scheme.
What image formats are supported?
Our tool supports all common image formats including JPG, PNG, WebP, and GIF. The maximum file size is 10MB. The processed image will be saved in PNG format to preserve quality.
Is my image data secure and private?
Absolutely! All image processing happens directly in your browser using HTML5 Canvas. Your images are never uploaded to our servers or stored anywhere. The tool works completely offline once loaded.
Can I undo mosaic effects?
Yes! The tool includes an undo function that lets you revert your last action. You can also clear all mosaic effects and start over, or load a new image at any time.
How do I adjust the mosaic intensity?
Use the "Mosaic Size" slider to control the intensity. Smaller values (5-10) create fine, subtle mosaic effects, while larger values (30-50) create more pronounced, blocky effects for stronger privacy protection.
