Select the Blur tool from the toolbar. Click and drag to define the rectangular area you want to blur. The area is obscured with a Gaussian blur effect that hides details while preserving the general shape and color of the content.

Use the blur radius slider in the properties panel to control how much the content is obscured (1–20px). A low value creates a subtle soft-focus effect, while a high value makes content completely unreadable.

Apply Gaussian blur to hide sensitive information while keeping context.

Select the Pixelate tool from the toolbar. Click and drag to define the area. The content is replaced with a mosaic of large colored blocks, making the original content unrecognizable.

Use the block size slider (8–40px) to control the mosaic resolution. Larger blocks make content more thoroughly redacted. Smaller blocks create a finer mosaic that still obscures detail. A small random variance is applied to each block for added security.

Apply mosaic pixelation to redact content with a blocky effect.

Select the Highlighter tool from the toolbar or press `8`. Click and drag across the area you want to highlight. The highlighter applies a semi-transparent color overlay that mimics a real highlighter pen.

Pick any color from the color picker. The highlighter applies a semi-transparent fill (40% opacity) so the content beneath remains visible.

Highlight text and areas with a semi-transparent marker effect.
