Frequently Asked Questions

How do I redact text in a screenshot?

Upload your screenshot, then draw rectangles over sensitive areas. Choose blur, pixelate, or solid black fill.

Is my screenshot uploaded to a server?

No! All processing happens in your browser. Your screenshots never leave your device.

Can I undo redactions?

Yes! Each redaction can be undone individually. Only the final exported image has permanent redactions applied.

Why the iPhone "Highlighter" is a Security Risk

Millions of users mistakenly use the standard "Highlighter" or "Pen" tool built into iOS/Android photo editors to black out bank balances, passwords, and sensitive text. The problem? These tools are often translucent.

If you scribble over an email address with a black iPhone marker, anyone can download your image, open the standard Photos app, and maximize the Exposure, Brilliance, Shadows, and Contrast sliders. The hidden text will instantly become visible beneath the marker strokes.

The "Destructive" Pixel Advantage

Our Privacy-First Redactor does not simply place a layer on top of your photo. It reads the raw mathematical pixel data in your browser's memory and performs Destructive Editing.
