Stamp any PDF — without uploading it

Add text, a logo, a watermark or full Bates numbering to any PDF, and download the result in seconds. Everything happens inside your browser — your document is never sent to a server, so there is nothing to leak and nothing to delete afterwards.

No account. No upload. Free while in beta.

The PDF Overlay editor with a document open: a large diagonal DRAFT watermark across the page, an APPROVED logo stamp, and a red Bates stamp reading ABC-000123-A · CONFIDENTIAL along the bottom.

Your file never leaves this browser

There is no upload step. The PDF is opened, edited and saved entirely on your own machine.

What it does

Everything you can put on a page

Three kinds of overlay — text, an image and a stamp block — each positioned, styled and scoped on its own.

Add text to a PDF — any font, any angle

Type what you need and place it anywhere on the page. Drag it, rotate it, resize it by its corners, or type exact coordinates if you need it in the same spot on every document.

  • Multi-line text with real line breaks
  • Bold, italic, underline and strikethrough
  • Any size, any rotation, any colour, adjustable opacity
  • Double-click the text on the page to edit it in place
Try it
The Text tool with DRAFT typed in, showing font, size, angle and opacity controls beside the page.

Watermark a PDF without uploading it

Set the text large, turn the opacity down, angle it across the page and apply it to every page at once. Put it behind the page content and it sits under the text like a real watermark instead of covering it.

  • On top or behind the page content
  • Any opacity, from a faint tint to fully solid
  • Applies to every page in one action
Try it
A DRAFT watermark set to Behind content, with the document's body text showing through the letterforms.

Bates numbering for legal documents

Number a whole production in one pass. Set a prefix, a starting number and how many digits to pad to, and every page gets its own sequential Bates number — combined, if you want, with a confidentiality legend, the date and a page count.

  • Prefix, zero-padded counter and suffix — ABC-000123
  • Combine up to four elements in one stamp block, in any order
  • Numbering follows each page's real position in the document, so stamping only some pages leaves the sequence honest rather than renumbering it
  • Save the scheme and reuse it for the whole matter

Add a logo, signature or image to a PDF

Drop a PNG or JPEG straight onto the tool and place it on the page. Aspect ratio stays locked while you resize, so a logo never comes out stretched.

  • Drag and drop, or pick a file
  • Move, scale and rotate directly on the page
  • Sits on top of the page or behind it
  • Adjustable opacity for faded background marks
Try it
An APPROVED logo placed on the page and selected, with its transform handles and the Image tool's width, angle and opacity controls.

Stamp every page, or only the pages you choose

Apply the overlay to the whole document or to a specific selection, the same way you would in a print dialog.

  • All pages, the current page, odd pages or even pages
  • Custom ranges like 2, 5-7, 10
  • The preview shows exactly which pages are affected before you save
Try it
Apply to set to Odd pages, with the preview showing a stamped page, a clean page and a stamped page in sequence.

Try it with one of your own documents

It opens in the browser, nothing uploads, and you can close the tab if you change your mind.

A live preview of the whole document

Scroll through the entire PDF exactly as it will be saved. The overlay renders on every page it applies to, so there is no guessing and no save-and-check loop.

  • Continuous scroll through all pages
  • Zoom from 25% to 400%, or pinch on a trackpad
  • Drag, rotate and resize directly on the page
A 42-page document scrolled in the continuous preview at 68% zoom, two consecutive pages visible, both stamped.

Use your own fonts in a PDF stamp

Pick from the built-in faces or upload the font your brand actually uses. Uploaded fonts are stored in your browser only — like your documents, they are never sent anywhere.

  • Built-in Helvetica, Times and Courier
  • Curated extras, including a monospace face for reference numbers
  • Upload your own TTF, OTF, WOFF or WOFF2
  • Set a default so every new document starts right

Save your stamp settings and reuse them

Set a stamp up once and save it by name. Load it on the next document and everything comes back — position, size, colour, font, layer and the whole Bates scheme.

  • Save any number of named configurations
  • Reuse them across documents and sessions
  • Rename and delete from one place
  • Your text and images are not saved with them, so a configuration stays reusable

Stamp a PDF without breaking its links

The original document is left alone. Stamping on top of the page keeps annotations, hyperlinks, form fields and metadata exactly as they were.

  • Your source file is never modified — you download a new copy
  • Links, annotations and form fields survive
  • Page sizes and rotation are preserved, including mixed-size documents

FAQ

Questions people ask first

Is it really free?

Yes. Every feature is free while the tool is in beta. There is no card, no trial, and no account.

Do you upload my PDF anywhere?

No. The file is opened and edited by your browser, on your machine. Nothing is transmitted, so there is no copy of your document on any server — including ours.

Do I need an account?

No. Open the page and start.

Does it work offline?

Once the page has loaded, the stamping itself needs no network.

What is Bates numbering?

A sequential numbering scheme used to identify pages in legal discovery — usually a prefix, a zero-padded number and sometimes a suffix, like ABC-000123. Each page gets a unique identifier so it can be cited unambiguously.

Can I stamp only some pages?

Yes — all pages, the current page, odd, even, or a custom range like 2, 5-7, 10.

Will it break my links or form fields?

No, as long as the overlay sits on top of the page. Placing it behind the page content needs the file to be rebuilt, and links, annotations and form fields do not survive that — the tool tells you when this applies.

Can I edit the existing text in my PDF?

No. This tool adds new content on top of a page; it does not change what is already there. If you need to rewrite the original text you need a full PDF editor.

What file types can I add as an image?

PNG and JPEG directly. Other formats your browser can display are converted automatically.

Is there a file size limit?

Only what your own machine can handle. Nothing is uploaded, so there is no server-side cap.
