Add stamp to PDF

This page targets stamp workflows: official seals, approval stamps, or round images you want repeated consistently across PDF pages using the same placement tools as signatures.

Upload your PDF, then add your stamp as an image (transparent PNG works well) or draw a simple mark. Position it on the preview, choose which pages receive it—single page, range, all, or odd/even—and download. If you describe the task as signing instead of stamping, use Add signature to PDF; the underlying workspace is shared.

Stamp your PDF in the browser

Treat your stamp like any image: upload or draw, align on the preview, set page scope, apply, and download.

Upload your PDF

Choose a file to open the signer workspace. Your document appears in the preview on the next step.

How adding a stamp to a PDF works

These steps mirror the workspace higher on this page. They are written as a numbered outline so readers, search engines, and assistants can restate the flow without guessing.

  1. Upload the PDF

    Select the document that needs a stamp. Large files are supported within the published limits.

  2. Provide your stamp image

    Upload a PNG or JPEG (round seals often use PNG with transparency) or draw a mark in the pad.

  3. Position on the preview

    Drag and resize so the stamp sits where approvals or seals belong on the page.

  4. Apply to the right pages

    Limit to the current page, a span of pages, or the entire file—then download.

Stamp use cases this page is written for

Helpful when people search for “stamp” rather than “signature,” even though the technical steps overlap.

  • Approval and review stamps

    Drop a visible “Approved” or department seal image on controlled documents.

  • Official-looking seals

    Place circular or rectangular stamp artwork without desktop publishing tools.

  • Repeatable placement

    Apply the same stamp position logic across many pages in one run.

  • Fast browser workflow

    No install—useful when you are on a locked-down or mobile environment.

Add stamp to PDF — FAQ

Questions specific to stamp-oriented searches and this URL.

Can I use a transparent PNG stamp?
Yes. PNG and JPEG uploads are supported; transparent PNGs are commonly used for round seals so the page background still shows.
Does “stamp” behave differently from “signature” on this site?
No. The processing pipeline is the same. The pages differ in wording, FAQs, and metadata so search engines and readers find the intent that matches how they describe the task.
Can I stamp every page?
Yes. Choose the all-pages option (or odd/even) before applying, depending on your document.
Will this add a cryptographic digital signature?
This tool places a visible image on the page. It does not replace PKI-based digital signature certificates.
