How do I pixelate an image online for free?

Upload your photo to our online image pixelator, select whether to pixelate the full image or a specific region, adjust the pixel block size slider to your preferred strength, and click Save & Download. The tool is 100% free with no sign-ups or watermarks.

Can I pixelate only a part of my image or a face?

Yes. Switch to Selective Censor mode and use the brush, rectangle, or circle tools to paint or drag masks over faces, license plates, or text. Only the selected areas will be pixelated, leaving the rest of the image in full original resolution.

What is the difference between pixelation and blur?

Pixelation groups pixels into large, distinct square blocks (mosaic effect), producing a retro, geometric appearance. Blurring uses Gaussian smoothing to blend colors together seamlessly without visible block edges. Both obscure details, but pixelation gives a clear visual signal that content was redacted.

Is pixelation completely secure for redacting sensitive data?

Pixelation obscures information effectively for everyday sharing and privacy. However, for extremely sensitive information like passwords, credit cards, or government IDs, advanced machine learning de-pixelation tools can sometimes approximate original text. For maximum legal security, use our Solid Blackout redaction style.

Are my images uploaded to any remote server?

No. All image processing, pixelation algorithms, face detection, and exports run entirely client-side within your web browser. Your images never leave your local device, ensuring total data privacy.

Can I adjust the size of the pixel blocks?

Yes. You can use the Pixel Size slider to set block dimensions from 2px (subtle) to 100px (heavy mosaic), or click one of the quick preset chips (Fine, Standard, Strong, Retro, Heavy) for instant tuning.

Does pixelating reduce the overall image resolution?

No. When you export your image, it is saved at the exact original pixel dimensions and resolution of the uploaded source file. In selective mode, unmasked areas retain 100% of their original clarity.

Can I pixelate photos directly on my smartphone?

Yes. Our tool is fully optimized for mobile devices. You can upload photos directly from your iPhone or Android photo library, paint or drag masks with touch gestures, and download the edited file directly to your device.

What image formats are supported?

You can upload JPEG, PNG, WebP, SVG, and BMP images. You can export your processed image in lossless PNG or compressed JPEG with custom quality controls.

Can I use this tool to create 8-bit retro pixel art?

Yes! Selecting Full Image mode and choosing a moderate to large pixel block size (e.g., 20px to 40px) instantly converts modern photography and graphics into vintage 8-bit and 16-bit pixel art styles.
