Why use this tool
Made for sensitive material
Sometimes only a small part of an image is sensitive: a face in the background, a name in a table, a price on a document, or a location on a map. Blurring the whole image would destroy its usefulness.
This tool gives you precise control over exactly which part of an image gets redacted. Draw a box as small or large as you need, in any position, and the effect is applied only within that area.
Questions
Frequently asked questions
Can I blur just one small area of an image?
Yes. You can draw a selection of any size, from a tiny word to a large section. The effect is applied only within the box you draw.
Can I blur a face in a photo?
Yes. Draw a box over any face to blur, pixelate, or black it out. This works on any part of the image, not just text.
Will blurring one part affect the rest of the image?
No. Only the area inside your selection is affected. The rest of the image remains unchanged.
Is the blur reversible after downloading?
No. Once downloaded, the effect is permanently applied to the image. You can undo selections before downloading using the Undo button.
What is the difference between Blur, Pixelate, and Black Box?
Blur creates a smooth frosted-glass effect. Pixelate replaces the area with large colored blocks. Black Box covers with solid black and is the strongest visual redaction.
Can I blur a background instead of the foreground?
Yes. Draw your selection over any region, including the background. The tool does not distinguish between foreground and background elements.
Is there a limit to how many areas I can blur?
No. You can add as many blurred regions as you need. Each drag creates a new independent selection.
Can I resize or move a selection after placing it?
Not directly, but you can click Undo to remove the last selection and redraw it in the correct position.
Will the blurred image have a lower resolution than the original?
No. The downloaded image has the same dimensions and resolution as the original. Only the selected area changes.
