Add Stamp to PDF

How to Add a Stamp to a PDF

1. Drop your PDF onto the tool, or click Choose PDF File.
2. Design the stamp. Start with a Quick Preset such as Approved, Draft or Confidential, or type your own Stamp Text (up to 40 characters) and an optional Sub-text like a date. Pick a Stamp Style: Box, Round, Oval, Diagonal, Badge or Plain.
3. Fine-tune it. Set the color, Fill Mode, Font, Font Size, Border Width, Opacity, Rotation and the stamp Width and Height. The preview updates as you go.
4. Place it. Click Place Stamp, click anywhere on the page, or use a Quick Position button from Top Left to Bot Right.
5. Move to other pages with Prev and Next and place more stamps. A stamp goes on the page you are viewing. Remove one from the placed list, or use Clear Page.
6. Choose Export Quality and Output Quality, then click Export Stamped PDF. The file is saved with _stamped added to the name.

Why Use This PDF Stamp Tool

• Your file stays on your device. The PDF is stamped by code running in your browser. Nothing is sent to a server.
• Build the stamp you need. Nine presets, six shapes, outline or filled looks, five fonts, and sliders for opacity and rotation.
• Exact placement. Click straight on the page or snap to one of nine positions, and preview it on the real page first.
• Sharpness you choose. Export Quality (1.5x, 2x, 3x) and Output Quality (95%, 85%, 75%) trade sharpness against file size.

Good to know: the export redraws every page as an image, including pages with no stamp. In the new file the text is no longer selectable or searchable, and links and form fields stop working, so keep your original. Apply To copies the stamps of the page you are viewing to all, odd or even pages when you export. A placed stamp cannot be dragged afterward. Remove it from the list and place it again.

FAQ

How do I add an Approved or Confidential stamp to a PDF?

Drop your PDF onto the tool, click the Approved or Confidential preset, then click Place Stamp or click where you want it on the page. Click Export Stamped PDF to download.

Can I stamp every page at once?

Yes. Place the stamp on the page you are viewing, then under Apply To pick All Pages, Odd Pages or Even Pages before you export. The same stamp is added to those pages in the same position.

Can I make my own stamp text?

Yes. Type up to 40 characters of Stamp Text and an optional Sub-text of up to 50, such as a name or date. Choose a style, color, font, opacity and rotation.

Will the text in my PDF still be selectable after stamping?

No. Every page is redrawn as an image when you export, so text can no longer be selected or searched. Keep your original file for that.

Can I move a stamp after placing it?

No. Delete it with the x button in the placed list, or click Clear Page, then place it again in the new spot.

Is my PDF uploaded anywhere, and is there a size limit?

No. The PDF is processed in your browser, so your file stays on your device. Your file size limit is shown on this page, and a free account raises it.
