Pixelate vs. Blur: Which to Use When Redacting Photos
PrivShot offers two styles: pixelate (mosaic blocks) and blur (a soft Gaussian). Neither is safer by nature — set either one strong enough that the detail is gone. Choose by look: pixelate reads as "obviously hidden," blur looks more natural.
The short answer
- Pixelate when you want it to look redacted — documents, screenshots, anything you’re posting publicly where “clearly censored” is the point.
- Blur when you want the photo to still look candid — a bystander’s face in a travel shot, say.
- Either way, turn the strength up. Security comes from strength, not style.
Why it works this way
People assume a mosaic is more secure than a blur, or vice versa. In practice a weak version of either can leak the underlying detail, and a strong version of either destroys it. PrivShot lets you pick the style for how it reads to a viewer, and set the strength for how safe it actually is — those are two separate decisions.
Tips & edge cases
- Don’t rely on a light mosaic. Coarse-but-shallow pixelation is the classic way redactions get reversed. Push the strength.
- Match the medium: pixelate for anything official-looking, blur for candids.
- You can mix — use the detector for auto-redaction and the manual brush for extras, both in your chosen style.
FAQ
Which is more secure, pixelate or blur? Neither is inherently safer — what matters is strength. A strong setting of either destroys the detail; a weak setting of either can leak it.
Why choose pixelate? Pixelation reads clearly as “deliberately hidden,” which is useful for documents and screenshots you’re sharing publicly.
Why choose blur? A Gaussian blur looks softer and less jarring on faces in a candid photo you still want to look natural.
