Why Use This Tool?
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.
