Pixelation Is Redaction Only If It Is Verified

Blurring and pixelating are different guarantees: a blur can occasionally be reversed with deconvolution tools, while a true pixel block (averaging each block to one color) destroys the original detail permanently. The redaction rule that actually protects people: pixelate the region, export, and re-open the exported file to confirm the data is unrecoverable — applying the effect in an editor and screenshotting the result is where leaks happen. Faces and license plates need block sizes small enough that no recognizable feature survives.

How Pixelation Hides Detail

  1. Load the image that contains the region you want to hide, such as a face, license plate, or personal detail.
  2. Adjust the tile size, which controls how large each pixel block appears. Bigger tiles mean a stronger, more anonymous effect.
  3. Paint over the sensitive areas using the mouse, a touchscreen, or a stylus. You can resize the brush and undo single strokes.
  4. Export the pixelated image as a new local file. The original is never overwritten.

Example: Redacting a License Plate

Censor a license plate
Input: Photo with a readable plate, tile size 16
Output: Same photo with the plate fully pixelated
A tile size of 12–16 px on a 1920 px-wide photo makes text impossible to read while keeping the surrounding scene intact.
Hide a bystander face
Input: Group photo, face in the background
Output: Photo with the face covered by a pixel block
Covering a face with pixelation is a common privacy practice before publishing photos of events or public spaces.

Common Questions

Can pixelation be reversed?

No. Pixelation averages the colors of each tile, permanently destroying the original detail within the painted area. This is exactly what makes it a reliable censorship method.

Does the tool upload my image?

No. All pixelation is computed in your browser on the original pixel data. Files are never sent to a server.

Pixelation or blur — which is stronger?

Pixelation is generally considered stronger because it replaces whole blocks with averaged colors. Heavy blur can sometimes be partially reverse-engineered; pixelation cannot.
