Hiding something before you share it
A face, a licence plate, a house number, an address on an envelope, a name on a screenshot, an account number on a statement. Select the area and it is obscured.
Pixelation can sometimes be undone — blocking cannot
Worth understanding before choosing. Pixelation averages blocks of pixels, and where the hidden content is from a small known set — a six-digit number, a licence plate format, a short word — it is sometimes recoverable by brute force: generate every candidate, pixelate each one, and see which matches. This has been demonstrated on real redactions.
Blur is generally harder to reverse than pixelation but is not proof against it either. Solid black is the only option here that is genuinely irreversible, because the original pixels are replaced rather than transformed.
For anything that actually matters — an account number, a date of birth, a signature — use black.
Strength
Set high enough that no shape remains. A face pixelated at strength 6 is often still recognisable to someone who knows the person; at 25 it is not. When in doubt, more.
Select generously
Cover more than you think you need. A partially covered plate or a face with an ear showing gives away more than people expect, and context in the surrounding image narrows the possibilities further.
The metadata too
Obscuring a face does nothing about the GPS coordinates in the file. Strip the metadata as well — a censored photo that still names the location it was taken has not been censored.
It runs on your device
The photo is never uploaded, which matters most for exactly this tool.
Common questions
Which mode is safest?
Solid black. It replaces the pixels. Pixelation and blur transform them, and pixelation of short known content has been reversed in practice.
Can pixelation really be undone?
For short content from a known set — a six-digit number, a plate — yes, by brute force. It has been demonstrated on real redactions.
How strong should the effect be?
Strong enough that no shape remains. A face at low strength is often still recognisable to someone who knows them.
Should I cover more than the object?
Yes. Partial coverage plus surrounding context gives away more than people expect.
Is the photo uploaded?
No — which matters more for this tool than any other here.
