How it works

## Watermark 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. **Choose More › Watermark**

Pick Draft or Confidential, or type your own words.

Your options on a Mac

## Three ways to do it, honestly compared.

### Preview (built in)

No watermark tool in Preview.

- Free
- Can’t add a watermark
- Text boxes per page only

### 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.

- Draft, Confidential or your words
- Drawn into every page
- Prints with the page

## Watermarks that stay put

Some apps add watermarks as annotations anyone can select and delete. Sheaf draws the words into each page, so they print and stay with the file.

## Watermark per recipient

Sending the same document to several people? Watermark a copy for each one (“Prepared for Jane Doe”) to discourage forwarding, then [add a password](https://sheafai.app/password-protect-pdf-mac).

**Sheaf for Mac**

Every PDF tool, right where you drag the file.

- Works offline
- Originals never changed
- Undo any result

## Questions

Can I add a watermark in Preview?

No. Preview has no watermark tool.

Can a watermark be removed?

Sheaf draws it into the page, so it can’t be clicked away. Determined people with editing tools can still alter any PDF.

Can I use my own words?

Yes. Type any text, like your company name or “Copy for review”.
