I blurred a fabricated API key, then ran Richardson-Lucy deconvolution with the exact kernel to see how much came back. The honest answer, with images.

Blanket-blurring a screenshot makes it useless as documentation. How targeted detection finds only the sensitive regions - and where it still needs a human.

Blurring and pixelation are reversible transformations. Here is why the original characters are still mathematically present in the file, and what to use instead.

Step-by-step redaction in Snipping Tool, Paint and SnapShield AI - including the checks that tell you whether the sensitive pixels are actually gone.

Screenshots in support tickets and documentation are personal data. A practical checklist of what to remove, why reversible blur is a compliance problem, and how to keep a defensible record.

Four Windows tools judged on one question - does the sensitive data actually leave the exported file? Includes where our own tool is the wrong choice.

Online redaction tools ask you to upload the exact file you are trying to protect. Here is why that is backwards, and how to do the whole job offline on Windows.

Blurring a face rarely anonymises it. What re-identification actually relies on, why partial covering fails, and how to remove a face so it stays removed.
