Frequently Asked Questions

What's the difference between blur and pixelate effects?
Blur creates a smooth, gradual transition that maintains color information while reducing detail. Pixelate creates a mosaic effect with distinct blocks, making content unreadable while preserving general shapes and colors.
Can I apply different effects to different parts of the same image?
Yes! Use the brush tool to apply effects selectively, then switch between blur and pixelate modes to apply different effects to different areas. The eraser tool lets you remove effects from specific areas.
Will the image quality be reduced after applying effects?
No, the original image resolution and quality are preserved. Only the areas where you apply effects are modified, and the rest of the image remains at full quality.
Can I undo individual brush strokes?
Yes! The tool includes full undo/redo functionality. You can undo individual brush strokes and eraser actions using the Undo button or Ctrl+Z keyboard shortcut. Redo is available with the Redo button or Ctrl+Y shortcut.
Are there any file size limitations?
The tool supports files up to 50MB and all common image formats. Larger files may take longer to process but will work properly on modern devices.
How does the undo/redo functionality work?
The tool maintains a history of up to 20 editing actions. Each brush stroke or eraser action is saved automatically. Use the Undo/Redo buttons or keyboard shortcuts (Ctrl+Z/Ctrl+Y) to navigate through your editing history.
