How it works

How to stamp or watermark a PDF on Mac or Windows

  1. Choose text, a logo or both

    Type the words, with tokens for the page number, total pages, date and file name. Logos can be PNG, JPG, WebP, BMP or SVG.

  2. Place it

    Snap it to one of nine positions or drag it in the Stamp Studio. Set size, opacity and rotation, and choose all pages, the first, the last or a range.

  3. Get stamped copies

    Each copy ends in -stamped and the page’s own text is unchanged. Customize one file in the Studio when it needs a different stamp.

Choose the placement

One mark, a tiled watermark, or a mark behind the text.

Single puts one stamp where you choose. Tiled repeats it across the page. Behind page content blends it in, so the page’s own text reads on top.

  • Single

    Start here

    One stamp per page, in one of nine spots or anywhere in the Studio.

    Best for status marks, logos and page footers.

  • Tiled

    The stamp repeated across the whole page.

    Best for proof watermarks with a client name.

  • Behind page content

    The mark sits under the text, like a background watermark.

    Best with a dark stamp at low opacity.

The alternative

Why not watermark it on a website?

Online tools can put a word across a PDF with nothing to install. For client proofs and branded deliverables, here is where they differ.

Questions

Before you download

More answers in the help center.

Is it really free?

Every tool is free for 3 days, with no account and no card. After that, Hangar is a one-time payment from $45, with updates for the version you buy. There is no subscription.

Is the stamp text searchable?

No. The stamp is added as a picture, so its words cannot be selected or searched. The page’s own text stays selectable and searchable.

Can someone remove the stamp?

Someone with a PDF editor could. A stamp marks a document, it does not secure it. Protect the stamped copy with Encrypt PDF to stop casual changes.

Can I make a faded watermark?

Yes. Lower the opacity, tile it across the page, and turn on Behind page content so the text reads on top of it.

Can I use my own logo?

Yes. Stamp text, a logo image, or both together, positioned and scaled however you like.

Do page numbers and dates fill in automatically?

Yes. Tokens for the page number, total pages, date, and filename are replaced on each page as it is stamped.

Does anything get uploaded?

No. Your files are processed on your computer and never sent anywhere. Hangar sends anonymous usage counts to improve the app, never file names or contents, and you can turn that off in Settings.

Does one license cover Mac and Windows?

Yes. A license works on any mix of Mac and Windows computers. Solo covers 1 computer, Crew 3 and Fleet 10.
