Pixelate Image
Apply an adjustable block-pixel effect to an image. Your files are never uploaded to our servers. ToolkitPoint processes them on your own computer, so confidential documents stay with you.

How to use Pixelate Image
- Pick one or more screenshots or photos through "Choose an image"; a preview appears below the settings.
- Drag on the preview to mark rectangles or ellipses to censor (or type region percentages and press "Add region from numbers"). With no region, the whole picture is censored.
- In "Censor effect" choose Mosaic, Soft Blur, Solid block or Random scramble, and set the block size or blur strength with the slider or number box.
- Use "Show at actual size" to inspect the result, "Undo last region" to fix mistakes, and read any warning about weak settings.
- Choose PNG, JPEG or WebP, press "Create censored image(s)" and download each file or the ZIP.
Worked example
Load a screenshot, choose "Solid block", draw a rectangle over an account number and an ellipse over a face, then export PNG. Only those two areas change; the rest of the screenshot is untouched, and the result has no camera or GPS metadata.
When to use this tool
- Obscuring a whole screenshot preview before sharing a thumbnail of it.
- Producing a blurred background version of a photo for a slide.
- Creating a retro low-resolution look from a portrait.
Important limitations
Light pixelation or blur can be partly reversed or guessed; for faces, plates or text use Solid block or Random scramble. Regions are marked by hand; there is no automatic face or text detection.
Frequently asked questions
Can I pixelate just one face or a license plate?
Yes. Draw a rectangle or an ellipse around it and only that region is changed; everything else stays pixel-for-pixel identical. The same regions (stored as percentages) are applied to every photo when you load a batch.
Does it detect faces or text automatically?
No. Automatic face and text detection would need a model or browser feature that is not available everywhere, so you mark the regions yourself.
Is pixelation safe for hiding text or faces?
Not always. Light pixelation or blur can sometimes be partly reversed or guessed, especially for text, and the tool warns you when your setting is light. For real redaction choose "Solid block" (an opaque colour) or "Random scramble", which keeps none of the original pixels in the area.
How is the block size used?
Each region is shrunk to one cell per block and enlarged without smoothing, so cells are aligned to the region's corner. At size 16 a 160 x 96 region becomes 10 x 6 cells.
What happens to the photo's metadata?
Exported images are redrawn on a canvas, so EXIF data such as GPS position, camera model and dates is not included in the result.
Which format keeps it exact?
PNG stores the result without compression noise. JPEG adds artefacts around block edges, and its export has no transparency.
