How to Redact a PDF

Black out names, account numbers or signatures so they cannot be recovered from the file.

Step-by-step

  1. 1Choose your PDF. It opens on your device and is not uploaded.
  2. 2Drag over each private detail. Go through every page.
  3. 3Click "Redact PDF".
  4. 4Download the new file, then open it and check every page.

Why a black box is not always enough

  • A shape drawn over a PDF can leave the words underneath in the file.
  • Filero paints the area black on an image of the page and builds a new PDF from those images.
  • The original text layer and document details are left behind.

Before you share the file

  • Check every page, because only marked areas are hidden.
  • Pages become images, so text cannot be searched afterwards.
  • The file can be larger than the original.

Frequently asked questions

Can redacted text be recovered from the file?

No text from the original PDF is copied into the new file. Each page is an image with the marked area painted black, and Filero reads the finished file back to confirm it has no selectable text.

Is my PDF uploaded?

No. Redact PDF runs in your browser, so the document stays on your device. The site can still send its usual analytics, but your file and its contents are never part of that.

Why can I no longer select or search the text?

Every page becomes an image. That is what removes the original text, including text you did not mark. If you need searchable text, keep your original safe and redact only the copy you share.

Does it find private details for me?

No. You choose what to hide by dragging over it. Check every page, because only the areas you mark are covered.

Does it work on scanned PDFs?

Yes. Scanned pages are already images, and the boxes work the same way.
