Frequently Asked Questions
About This Tool
Blur and pixelation hide content by destroying detail, but neither is as final as a solid block. A light Gaussian blur leaves much of the underlying structure intact, and pixelation over a known, limited set of possibilities, such as a registration plate, has been reconstructed before. Strength is what decides whether a redaction is a hint or a wall.
Each region is a box you drag over the preview. On export the full-resolution image is rendered twice, once sharp and once with the effect: blur applies a canvas filter whose radius is four times the strength setting, up to 40 pixels, while pixelate downscales the image and redraws it with smoothing switched off. Only pixels inside your boxes are copied from the effect version into the download.
Notes & Limits
- The exported file holds only the composited pixels, with no hidden original underneath, but a weak setting can still leave text legible. Check at full zoom.
- Regions are plain rectangles with no rotation, feathering or freehand outline, so an awkwardly angled subject needs several overlapping boxes.
- Pixelation block size is derived from the image's smaller dimension as well as the strength slider, so one setting bites harder on a small image.
- PNG input stays PNG, but JPEG and WEBP sources are both written as JPEG at quality 0.92, so a WEBP photo changes format on the way out.
