Frequently Asked Questions
What block size should I use?
Smaller blocks (2-10) create subtle pixelation while larger blocks (20-50) create dramatic mosaic effects. For privacy censoring, 15-30 is usually effective.
What is the difference between square and circle shapes?
Square mode fills each block completely for a classic pixel look. Circle mode draws each block as a circle on a black background for a more artistic dot-matrix effect.
Can I pixelate just part of an image?
This tool applies pixelation to the entire image. For selective pixelation of specific areas, use a dedicated image editor with selection tools.
Does pixelation reduce file size?
Pixelated images often compress better because they have fewer unique colors, which can result in smaller file sizes when saved.
