Pro Tips
Match Block Size to Content
Use 5-10px blocks for subtle artistic effects and 30-50px blocks when the goal is complete obscuration of readable text.
Pixelation Is Irreversible
Unlike blur, pixelation permanently destroys detail. Always work on a copy since the original data cannot be recovered.
Test on Small Areas First
Crop the sensitive region and test different block sizes before applying to the full image to find the ideal balance.
Combine with Blur for Security
For maximum privacy, pixelate first then apply Gaussian blur. This double layer makes AI-based reconstruction nearly impossible.
Frequently Asked Questions
What is pixelation used for?
Pixelation is commonly used for censoring sensitive content, creating retro/artistic effects, or anonymizing faces and text in images.
What does block size mean?
Block size determines how large each pixel block is. Smaller values create a finer mosaic, while larger values create more obvious blocky censorship.
Can I pixelate only part of an image?
Currently the tool pixelates the entire image. For selective pixelation, we recommend using the crop tool first.
Can I pixelate only part of an image?
The current tool applies pixelation to the entire image. For selective censoring, consider using our Blur Faces tool for face detection.
What block size should I use?
Larger blocks create a more obvious pixelation effect. Use 10-20px for subtle retro effects, 30+ for heavy censoring.
