Censor photo (blur, pixelate) online

Censor image areas online with blur censor, pixelate face, or solid redaction. Drag the mask, preview instantly, and download PNG in your browser.

What is photo censoring?

Photo censoring hides part of an image while leaving the rest visible, common for privacy, anonymity, or compliance. This tool acts as an image censor where you draw a rectangle or ellipse over any zone, then apply pixelate blocks, blur censor, or solid color inside that mask. Use it to pixelate faces, hide license plates, or redact text. Upload a photo, position the selection, tune block size or blur radius, preview beside the original, and download PNG in your browser.

Photo censor features

Regional blur censor, pixelate, and solid fill in the browser.

  1. Draggable censor zone: Move and resize the mask with handles—same interaction as crop.
  2. Rectangle or ellipse: Pick the mask shape that fits faces, plates, or UI elements.
  3. Three methods: Pixelate, blur, or solid color for the selected area only.
  4. Method controls: Block size for pixelate, radius for blur, hex color for solid fill.
  5. Live preview: Output updates when you move the zone or change options.
  6. PNG download: Save as censor-photo.png.

How to blur or pixelate part of a photo

Steps for online image censoring with blur or pixelate.

  1. Upload your image: Drop or click in the input panel (15 MB max).
  2. Position the censor box: Drag over the face, plate, or text you need to hide.
  3. Pick shape and method: Try pixelate for plates, blur for faces, or solid black for redaction.
  4. Download PNG: Save the censored image for sharing or publishing.

Tips for censored photos

Better censored image and blur censor results.

  1. Oversize the mask slightly: Include a small margin so edges of faces or text do not peek through.
  2. Pixelate for OCR resistance: Larger block sizes make small text harder to recover than light blur.
  3. Blur for natural scenes: Soft blur can look less harsh on faces in casual photos.
  4. Solid for legal redaction: Flat black or white blocks signal deliberate removal on documents.
  5. Check the preview zoomed: Inspect corners of the ellipse or rectangle before download.
  6. Keep the original: Archive the uncensored file separately if you may need it later.

When to censor photos

Typical uses for regional blur and pixelate.

  1. License plates: Pixelate plates in street photography before posting online.
  2. Faces and privacy: Blur bystanders or children when consent is unclear.
  3. Screenshots: Hide emails, names, or account numbers in UI captures.
  4. Social posts: Redact sensitive details while keeping the rest of the scene visible.
  5. Documents: Solid-color blocks for ID numbers on scanned forms.
  6. Quick anonymization: One zone at a time without a full desktop editor.

  4. No install: Works in modern browsers with Canvas 2D.
  5. Flexible masks: Rectangle and ellipse cover most redaction shapes.
  6. Honest scope: Single-zone censor per export—not batch or multi-mask editing.
