Redact a PDF without uploading it

Most online redaction tools send your file to their servers. Here, your PDF opens in your browser and the new file is made on your device; it isn't sent anywhere.

What happens to your file

  1. When you choose a PDF, your browser reads it from your device. It isn't sent to Blackbar or anyone else.
  2. Your boxes are drawn in your browser.
  3. Download PDF makes the new file in your browser and saves it to your device. Close the tab when you're done.

That's why a long file can take a moment: your own device does the work.

The site counts visits to its pages, but never your file or anything in it.

Questions

Do I need an account?

No. There's no sign-up and nothing to log in to.

Do I need to keep the tab open?

Yes, until you've downloaded the new PDF. Your boxes live in that tab.

Why does a long file take a while?

Your own device opens each page and builds the new file, so a long file or an older phone takes longer.

Is it free?

Yes, with no limit on files or pages.
