HOW TO

Three steps and done

  1. Add your PDF

    Pick which pages get the mark in the thumbnails. All pages start selected.

  2. Set text or logo and its look

    Text (up to 80 characters) and color, or a logo image (PNG, JPG, WebP). Size, angle, opacity, and an optional 3×3 repeat.

WHEN

Perfect for

  • Circulating a draft before sign-off

    Mark it “Draft” to avoid mix-ups.

  • A company logo on quotes and proposals

    Add your logo, see-through.

  • Marking only certain pages

    Pick just those pages in the thumbnails.

GOOD TO KNOW

Good to know

  • The logo file isn’t remembered — pick it again next time. Logos keep their original colors.
  • One PDF at a time, up to 50MB and 200 pages.
  • PDFs with passwords, digital signatures or form fields aren't supported yet. Bookmarks and attachments aren't carried over.
  • The PDF engine is downloaded once, about 4MB, the first time. It's fetched only after you pick a file, and other PDF tools reuse it.
  • Press Try a sample to try it without your own file. The Continue button on a result card carries on in another tool without adding the file again.

FAQ

Frequently asked questions

Where do my files get uploaded?

Nowhere. Everything is processed inside this device's browser, and closing the window clears both the files and the results.

The mark hides the text underneath.

Lower the opacity or reduce the size. With the 3×3 repeat, a smaller size works better.

Which devices has it been checked on?

We confirmed it in Edge and WebKit (the engine behind Safari) on Windows. Phones were tested by simulating a phone screen on a PC; checks on real Mac, iPhone and Android devices are still to come.
