Why Pixelate Images?
🔒 Privacy Protection
Pixelate faces, license plates, or personal info in photos before sharing. Unlike blur, pixelation creates distinct blocks that are impossible to reverse.
🛡️ Mosaic Censoring
Apply mosaic-style censoring to screenshots and photos. Perfect for redacting sensitive areas while keeping the rest of the image clear.
🎨 Retro Pixel Art
Create retro pixel art effects from any photo. Adjust the pixel block size to get the perfect 8-bit aesthetic.
⚡ Instant & Free
No signup, no limits, no watermarks. Your images stay on your device — they are never uploaded to any server.
Frequently Asked Questions
How do I pixelate an image?+
Upload your image, adjust the pixel block size slider to control the intensity of the mosaic effect, then download. Larger block sizes create stronger pixelation. All processing happens in your browser.
What's the difference between pixelation and blur?+
Pixelation replaces areas with solid-color square blocks (mosaic effect), while blur smoothly blends neighboring pixels. Pixelation is often preferred for censoring as it's clearly intentional and impossible to reverse.
Can I pixelate just part of an image?+
This tool applies pixelation to the entire image. For selective area pixelation, try ScreenSnap Pro which lets you draw pixelation regions directly on screenshots.
Is pixelation irreversible?+
Yes. Once downloaded, the pixelated areas cannot be recovered. The original pixel data is permanently replaced with averaged block colors, making it safe for redacting sensitive content.
