Fillstep

Hide confidential information

Redact a PDF on your phone, for real

Fillstep finds personal details in a PDF, lets you choose exactly what to hide, and writes a new PDF with those details removed from the file, not just covered.

How it works

  1. 01

    Pick a PDF

    Open Hide confidential information in Tools and choose a document from the app or from Files.

  2. 02

    Choose what to hide

    Fillstep lists what it found: emails, phone numbers, ID, passport and tax numbers, card numbers, IBANs, names, addresses, dates of birth and signatures. Tick what goes.

  3. 03

    Preview and keep the copy

    Check the preview page by page, then keep the new PDF. Your original stays as it was.

Removed, not just covered

A black box drawn over text can leave the text in the file, where anyone can copy it out. Fillstep writes a new PDF in which the details you chose are gone.

It finds the repeats too

When you hide a value of four or more letters or digits, Fillstep also finds its other whole-word mentions on every page, so an account number on page one and page four both go.

Done on your device

Scanned pages are read with the device's own text recognition. Nothing is uploaded while Fillstep searches the document.

Good to know

  • Available on iPhone, iPad and Android. Not on the Mac yet.
  • The free plan includes 1 PDF a month; Pro has no limit.
  • Fillstep finds details by their shape and by labels like Name or Account. Always check the preview: unusual layouts and handwriting can be missed.
  • A page with hidden details is saved as an image of the page; if it had selectable text, the remaining text is added back invisibly so it stays searchable.

Questions and answers

How do I black out a Social Security number in a PDF?

Open the PDF in Hide confidential information. Fillstep finds the number by its shape and its label; tick it, check the preview and keep the new copy.

Is a black rectangle on a PDF safe?

Not always. Many apps draw a box over the text and leave the text underneath. Fillstep removes the chosen details from the new file instead.

Is the original PDF changed?

No. Fillstep saves a new PDF and leaves the original untouched.

Can I redact a PDF on a Mac with Fillstep?

Not yet. Hide confidential information is on iPhone, iPad and Android today.
