Frequently Asked Questions
What block size is best for censoring private data?
A block size between 12px and 20px is ideal for completely masking credit card numbers, passwords, or faces.
Can I create retro video game style graphics?
Yes! Setting a larger block size (16px to 32px) converts photos into charming 8-bit / 16-bit retro game sprites.
