Image Pixelate
Free online image pixelation tool. Apply mosaic effects with adjustable intensity to protect privacy or create artistic effects. Process images locally in your browser.
How do I pixelate an image?
Upload an image by clicking or dragging it onto the upload area. Adjust the pixelation level using the slider, then click Apply to preview and download the result.
Can I pixelate only a specific area of the image?
Yes. Switch to "Area Selection" mode, then draw a rectangle on the image to select the region you want to pixelate. Only the selected area will be affected.
What pixelation levels are available?
The pixelation level ranges from 1 (no pixelation) to 100 (very pixelated). Higher values create larger pixel blocks for a stronger mosaic effect.
Is my image uploaded to a server?
No. All processing is done locally in your browser using the Canvas API. Your images never leave your device.
What is image pixelation used for?
Image pixelation is commonly used for privacy protection (blurring faces or license plates), censoring sensitive information, creating artistic effects, or anonymizing photos before sharing them online.
How does the pixelation effect work?
Pixelation works by dividing the image into small blocks and replacing all pixels within each block with the average color of that block. Larger blocks create a more pronounced mosaic effect.
Can I undo the pixelation effect?
No, pixelation is a destructive edit that permanently removes detail. However, you can always re-upload the original image and apply a different pixelation level.
What image formats are supported?
The tool supports all major image formats including JPEG, PNG, GIF, WebP, and BMP. The output will maintain the same format as the input.
Is there a file size limit?
There is no strict file size limit since processing happens in your browser. However, very large images may take longer to process and consume more memory.
Can I use this tool on mobile devices?
Yes, the tool is fully responsive and works on smartphones, tablets, and desktop computers. The interface adapts to your screen size.
Do I need to create an account?
No, the tool is completely free and requires no registration or login. You can start using it immediately.
Is the tool free to use?
Yes, the image pixelation tool is 100% free with no hidden costs, watermarks, or limitations on the number of images you can process.
