Frequently Asked Questions
Pixelating an image means replacing fine detail with larger visible square blocks so the original content becomes harder to recognize. It is commonly used to censor faces, license plates, text, private information, or other sensitive areas, and it can also be used as a deliberate visual style for retro or poster-like effects.
A good starting point for censoring is often around 15 to 20 pixels, especially for faces, text, or other details that should no longer be easy to recognize. The ideal size depends on the resolution of the image and how much detail is visible, so higher-resolution photos may need a stronger pixel size to hide the subject effectively.
No. Once the detail is replaced by pixel blocks and you save only the pixelated result, the original fine information is no longer present in that exported image. That is why pixelation is commonly used as a stronger privacy effect when you want the hidden detail to stay obscured.
Yes. In Select Area mode, you can draw and pixelate multiple regions one after another on the same image. This is useful when you need to hide several faces, multiple text sections, license plates, or different private details in one photo.
Pixelation replaces detail with visible blocky squares, while blur softens detail into an out-of-focus effect. Blur can look smoother and more natural, but pixelation is often stronger for censorship because it breaks the image into coarse blocks that make details harder to read or identify.
