Truly remove content — not just cover it

Draw rectangles over names, numbers, addresses or whole paragraphs, and export a PDF where those areas are physically gone. The marked pages are re-rendered to pixels with the regions blacked out and rebuilt from scratch — the original text or image simply no longer exists in the file. Everything runs in your browser; the document is never uploaded.

Why a black box is not redaction

Drawing a black rectangle over text in a normal PDF editor only adds a shape on top — the text stays in the file underneath. Anyone can select it, copy it out, or remove the box. Exactly this mistake has caused real-world leaks in court filings and government releases. Proper redaction must destroy the content, which is what the page rebuild here does.

The honest trade-off

Only pages that contain a marking are rasterized (rebuilt as a 150-dpi image): text on those pages is no longer selectable or searchable. Every page without markings is copied losslessly and keeps its text layer. For confidential documents that is the right trade — verifiably gone beats pretty.

How to redact

  1. Drop your PDF and navigate to the page with sensitive content.
  2. Drag rectangles over everything that must go — across as many pages as needed; hover a box to remove it again.
  3. Click redact and download. Spot-check the result: try selecting text where the boxes were — there is nothing to select.

One more step for truly clean documents

Redaction removes page content. Document metadata (title, author, creator) lives in a separate layer — clear it with the Edit Metadata tool before sharing if the document is sensitive.

Frequently asked questions

Is this real redaction or just a black box?

Real redaction. A black box drawn over text in a normal editor leaves the text inside the PDF — anyone can select, copy or extract it (a classic data-leak). Here, marked pages are re-rendered to pixels with the areas physically blacked out and rebuilt — the original content no longer exists in the file.

Is my document uploaded?

No. Marking and rebuilding happen entirely in your browser. A confidential document never leaves your device — which is exactly where redaction matters most.

What's the trade-off?

Pages containing redactions are rebuilt as images (150 dpi), so text on those pages is no longer selectable or searchable. All pages without markings are copied losslessly and keep their text layer.

Does it also remove metadata?

This tool removes the marked page content. Document metadata (title, author …) is a separate layer — clear it with the Edit Metadata tool before sharing if needed.
