Frequently Asked Questions
QDoes my photo get uploaded anywhere?
No. Blurring and pixelating happen entirely in your browser using the Canvas API. Your photo is never uploaded to a server.
QIs pixelation more secure than blur for hiding sensitive info?
Pixelation is generally considered harder to reverse than a Gaussian blur, since heavy blurring can sometimes be partially undone with specialised software. For highly sensitive content, use a strong pixelation setting.
QCan I redact more than one area in the same photo?
Yes — click "+ Add Region" as many times as you need. Each region can be moved and resized independently, and removed with the × button.
About This Tool
Each redaction region is a draggable/resizable overlay (Pointer Events, same interaction pattern as the Image Cropper). On download, the full image is rendered twice onto offscreen canvases at natural resolution — once sharp, once with a CSS canvas filter blur() or a downscale-then-upscale pixelation effect applied to the whole image — and each region's area is composited from the effect canvas onto the sharp canvas, so blur/pixelation only appears inside the selected boxes.
