Sobre esta ferramenta

Drawing a black box in a normal PDF editor often leaves the original words in the file. Anyone can copy or search them. True redaction flattens each page to an image after the boxes are painted, so the hidden text is gone. This tool does that in your browser for files up to 20 pages and 25 MB. Use it for account numbers, faces in a scan, or a National Insurance / SSN snippet before you email a PDF.

Como usar esta ferramenta

  1. Open the PDFCap is 20 pages / 25 MB so the flatten stays reliable on a laptop.
  2. Paint black boxesMark every region that must disappear. Check every page - redaction is permanent.
  3. Download the flattened PDFPages are rasterised so the original text layer cannot be recovered from this file.

Por que usar

  • Flattened pages, not fake black rectangles over live text.
  • Runs locally - the document is not stored on a server.
  • Clear size cap so phones do not freeze mid-job.

Usos comuns

  • Blacking out an account number on a US bank PDF.
  • Removing a UK National Insurance number from a form scan.

Dicas para melhores resultados

  • Zoom in. A missed digit is still searchable if you only cover the label.
  • After download, try selecting text in a reader - it should not copy the redacted words.

Erros a evitar

  • Using highlight or a black shape in the live PDF editor and calling it redaction.
  • Redacting a copy while emailing the original.

Perguntas frequentes

Yes in the practical sense: each page is painted then flattened to an image, so the original glyphs are not in the download. It is not a classified-document workflow with forensic certificates.

The editor keeps a live text layer for annotations. That is the opposite of redaction. This dedicated tool exists so we do not break editing.

20 pages and 25 MB. Split a longer file first.

Not from the downloaded file if you covered the region. Keep your own unredacted original in a safe place.

No. Rasterisation uses PDF.js and a canvas in your browser.
