About Image Blur & Pixelate

Image Blur & Pixelate hides faces, license plates, addresses, and other personal information in your photos. Drag a rectangle around the area you want to hide, or paint over it with the brush, then apply one of three effects: pixelate, blur, or solid fill (black or white).

Pixelate covers an area with coarse blocks — the classic way to censor a photo. Blur smooths the area for a softer, more natural look. Fill paints a solid color over the area to redact it completely. You can adjust the strength of the pixelate and blur effects, and the thickness of the brush, with sliders. Add as many regions as you need, and use "Undo" or "Clear all" to start over.

The tool supports JPG, PNG, GIF, and WebP, and you can download the edited image with one click. Every image is processed entirely in your browser and never uploaded to a server, so it is safe to use on photos for social media, marketplace listings, or blog posts — free and with no signup. Runs entirely in your browser.

How to use

  1. Drag and drop an image into the dropzone, or click to pick a file (pasting from the clipboard also works).
  2. Choose an effect — "Pixelate", "Blur", or "Fill" — and adjust its strength (or color for Fill).
  3. Pick a selection method: "Rectangle" to drag a box, or "Brush" to paint over an area.
  4. Enclose or paint over each area you want to hide, repeating as needed ("Undo" and "Clear all" let you start over).
  5. Click "Download" to save the edited image.

Use cases

  • Individuals hiding the faces of bystanders or children in photos shared on social media or a blog.
  • Sellers blurring out addresses, names, or shipping labels in marketplace and auction listing photos.
  • Anyone pixelating or blurring a license plate before posting a photo of a car or motorcycle.
  • Business users redacting email addresses, phone numbers, or confidential details in documents and screenshots with a solid fill.
  • Editing confidential images that cannot be uploaded (e.g. under an NDA) fully on your own device.

Notes

  • Maximum 50 MB per file. Supported formats are JPG, PNG, GIF, and WebP (GIF and WebP are exported as a single still PNG).
  • Pixelate and blur may not fully remove the original image data. Use "Fill" when you need to hide something for certain.
  • What you see in the preview is rendered into the saved image at the original resolution.
  • Output is JPG if the input is JPG; otherwise (PNG, GIF, WebP) it is saved as PNG to preserve transparency.
  • To download, add at least one region to hide — the image cannot be exported unedited.

FAQ

Are images uploaded to a server?
No. Pixelating, blurring, and filling all happen entirely in your browser. Your images are never sent anywhere, so even photos with personal information are safe to edit here.
What is the difference between pixelate, blur, and fill?
Pixelate covers an area with coarse blocks, blur smooths it for a more natural look, and fill paints a solid black or white color over it to hide it completely. Use pixelate or blur to obscure faces and plates discreetly, and fill when you need to remove information for certain.
Can pixelate or blur be undone later?
You cannot recover the original from an image you have already downloaded. If you need to hide information for certain, fill is safer than pixelate or blur — a weak pixelate or blur can sometimes leave the original content guessable.
How do I hide a complex shape?
Choose "Brush" mode to paint freely over the area you want to hide. It works well for hair, text in the background, and other shapes that are hard to enclose in a rectangle. You can adjust the brush thickness with a slider.
Which image formats are supported?
JPG, PNG, GIF, and WebP, up to 50 MB per file. On save, JPG input is exported as JPG, and other formats are exported as PNG to preserve transparency.
