PDF tool for Mac

# Redact a PDF on Mac. Really redact it.

Drawing a black box over text is not redaction: the words underneath can still be copied. Real redaction deletes them from the file.

**In short:** To redact a PDF on a Mac, drag it, pause and choose Redact in Sheaf. It finds names, emails, phone, card, account and ID numbers, you review them, and the text under each mark is deleted from the new copy.Updated 13 November 2026

How it works

## Redact PDF in three moves.

No app to open, no window to find. It happens where the file already is.

1. **Drag**

Start dragging the file from Finder, Mail, Photos or your desktop.

2. **Pause**

Hold still for a moment. Sheaf’s actions open in a circle around your cursor.

3. **Review and save**

Sheaf lists what it found. Add or remove items, then save a redacted copy.

Your options on a Mac

## Three ways to do it, honestly compared.

### Preview (built in)

Tools › Redact, then mark each item by hand.

- Free and built in
- You must find every item yourself
- Easy to miss one on a long document

### Online PDF sites

Upload the file to a website, wait, download the result.

- Your document goes to someone else’s server
- Free plans limit files, size or tasks per day
- Needs an internet connection

### SheafFastest

Drag the file, pause, let go.

- Finds names, emails, phone, card and ID numbers
- Deletes the text underneath, also in scans
- Original kept unchanged

## Why black boxes fail

If you cover text with a shape in a PDF editor, the original text usually stays in the file. Anyone can select it, copy it, or delete the shape. This has leaked court filings and government documents more than once.

## What Sheaf finds

Names, email addresses, phone numbers, payment card numbers, bank account numbers and national ID formats (like US Social Security numbers, UK National Insurance numbers, Australian TFNs and others), including in scanned pages it reads with on-device text recognition. You can add your own words too.

## Also remove what you can’t see

A PDF can carry the author’s name, edit history, comments and attachments. Before sending a redacted file outside, [remove hidden data](https://sheafai.app/remove-pdf-metadata-mac) too.

## Questions

Can I redact in Preview?

Preview has a Redact tool, but you mark each item yourself. Sheaf finds names, emails and numbers for you and removes the text underneath.

Can redacted text be recovered?

Not from a properly redacted file: the text is removed, not hidden. Keep the original somewhere safe if you need it later.

Does redaction work on scanned PDFs?

Yes. Sheaf reads scanned pages with on-device text recognition, so it can find and remove details in scans too.

Is it safe to redact PDFs online?

You would be uploading the very information you want to hide. Redact on your Mac instead.
