Add signature to PDF

Use this page to place a handwritten or image signature on a PDF and download a new file—optimized for people searching specifically for signature workflows.

The workspace below is built for contracts, forms, and sign-and-return tasks. Upload your PDF, add your signature, align it on the live preview, then choose whether it applies to the current page only, a custom page range, odd/even pages, or the full document. The same engine also powers our related stamp and logo pages.

Sign your PDF in the browser

Upload the document, add your signature, align it on the preview, choose page scope, and apply. Use the on-page outline to jump to FAQs or related tools.

Upload your PDF

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

How adding a signature to your 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 your PDF

    Choose a PDF from your device. It is sent to the server so pages can be rendered and merged when you apply your signature.

  2. Create or upload your signature

    Draw in the pad or upload a PNG/JPEG. The workspace treats it as an image you can position like a stamp or logo.

  3. Place and resize on the preview

    Drag the box on the preview and use the corner handle so the signature lines up with signature lines or blank areas.

  4. Choose pages and apply

    Pick this page only, a range, all pages, or odd/even—then apply and download the signed PDF.

When this signature page is the right choice

This URL is aimed at signature-specific searches. If you need a round stamp or a company logo instead, see the linked tools in this section.

  • Contracts and agreements

    Sign NDAs, SOWs, or engagement letters without a desktop PDF editor.

  • Government and school forms

    Place a signature image on PDF forms that were distributed as static files.

  • Remote sign-off

    Finish a sign-and-return step from any device with a modern browser.

  • Multi-page consistency

    Apply the same signature placement pattern across many pages in one action.

Add signature to PDF — FAQ

Scoped to this URL and the shared workspace. For site-wide questions, use the homepage FAQ.

Is adding a signature to a PDF free here?
Yes. This phase of the product is free for public use. Optional accounts or paid tiers may appear later and will be documented on the relevant pages.
Can I sign more than one page at once?
Yes. Choose this page only, a page range, all pages, or odd/even pages before you apply, depending on what the document needs.
How is this different from the add-stamp or add-logo pages?
The workflow is the same; each URL is written for a different search intent (signature vs stamp vs logo) so you can bookmark the page that matches how you describe the task.
What format is the download?
You get a new PDF with your placed image merged according to your options. Keep your original if you still need an unsigned copy.

Other PDF tools on PDF Tools

This site uses one page per workflow. The list below ties this page to the rest of the catalog on the homepage and to other routes under /tools/. Live tools open their own instructions and FAQ; upcoming tools link back to the homepage list until they ship.

  • 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.

    This entry links to the dedicated tool page at /tools/add-stamp-to-pdf, with its own workspace, steps, and questions.

  • Add logo to PDF

    Optimized for branding tasks: place a company or product logo image on PDF pages with the same placement and multi-page controls as signatures and stamps.

    This entry links to the dedicated tool page at /tools/add-logo-to-pdf, with its own workspace, steps, and questions.

  • Batch stamp PDF

    Focused on high-volume page coverage: one upload, one stamp placement pattern, then apply across many pages at once—ideal when “batch” is how you think about the job.

    This entry links to the dedicated tool page at /tools/batch-stamp-pdf, with its own workspace, steps, and questions.

  • Stamp PDF multiple pages

    Written for searches about partial coverage—when you need a stamp on several pages but not necessarily the whole file.

    This entry links to the dedicated tool page at /tools/stamp-pdf-multiple-pages, with its own workspace, steps, and questions.

  • Apply stamp to all pages PDF
