Why redaction exists

Blurring hides it.
Redaction removes it.

A blur keeps every pixel it started with — it just spreads them out. Given the original layout and a known blur radius, that is often enough to reconstruct what was underneath. Redaction has nothing left to reconstruct.

Nothing to recover. The pixels are replaced, not rearranged.

A dramatisation, not a real attack — but the principle holds. Use Redact when the content genuinely must not leak.

The toolkit

Six tools. One click each.

Edit

Click any text and rewrite it. Alt+R replaces every occurrence at once. Double-click an image to swap it for a local file.

Blur

Click to blur. Click again to go stronger, once more to clear. Reversible, which is exactly why Redact exists alongside it.

Redact Pro

A solid, irreversible block. Flattens text, images, video and canvas alike — nothing survives to be recovered.

Hide & Draw

Remove an element entirely, or drag a rectangle to blur any arbitrary region — no element required.

Annotate

Arrows, circles, text notes and a highlighter that keeps the text underneath readable. Boxes, a freehand pen and numbered step badges in Pro.

Screenshot

Capture what's on screen with every edit applied. The toolbar and overlays hide themselves first, so they never end up in the shot.

Two modes

Simple by default.
Powerful on request.

Most people need four tools and never think about it again. The rest is one click away, and stays out of the way until you ask.

Simple

What the toolbar opens with

  • Edit, Blur, Hide, Draw — the everyday four
  • Annotate — arrows, circles, highlighter, text notes
  • Undo, Screenshot, Reset

Nothing else on screen. Nothing to learn.

Pro

One click away

Everything above, plus

  • Redact — irreversible, unlike blur
  • Scope — apply a rule to one page or every page on the domain
  • Rules panel — review, locate, re-scope or delete any rule
  • Export / import your rules as JSON
  • Redo, plus a blur-or-block choice for drawn regions
  • Annotate: box, freehand pen, numbered steps

Your choice is remembered.

Privacy

It never phones home.
Not even once.

The extension makes no external requests of any kind. No telemetry, no analytics, no account. Everything you edit stays in your browser's local storage.

Works offline

No network calls, so nothing to intercept and nothing to leak.

Local storage only

Your rules live in chrome.storage.local. Never synced, never uploaded.

Minimal footprint

A 24-line script runs on pages, only to track the last right-clicked element. The editor loads on demand.

Auditable

MIT licensed, every line on GitHub, with the test suite that guards it.

presentable.

Free, open source, and about thirty seconds from being useful.
