Sign PDF
Draw a signature with your mouse or finger, type one, or upload a picture of your own, then place and size it anywhere on a page. This adds a signature image to the document — it is not a legally-binding electronic signature service.
This is not a legally-binding e-signature service. It places an image of a signature on your document. There is no identity verification, no audit trail and no tamper-evident certificate. For agreements that need a verifiable signature, use a dedicated e-signature provider.
Your file and options
Create a signature, choose where it sits, and download the signed copy.
Your document and your signature never leave this browser tab. Nothing is uploaded or stored, and no record of the signing is kept anywhere.
Result
Choose a PDF and create a signature to place it on a page.
About this calculator
This tool lets you place a signature onto a PDF page without leaving your browser. You can draw it, type it in a handwriting-style font, or upload an image, then position and resize it wherever it needs to go. It simply drops a picture of a signature onto the document, it does not create a legally verified electronic signature.
How to use it
- 1.Choose the PDF you want to sign.
- 2.Draw your signature, type a name, or upload a PNG or JPG of a signature.
- 3.Pick the page, then set the position across and down the page and how wide the signature should be.
- 4.Select Place signature and the signed copy downloads to your device.
Good to know
This tool stamps a picture of a signature onto the page. It does not verify who you are, does not record an audit trail, and does not add a tamper-evident certificate, so it is not the same as a certified electronic signature.
For contracts that must stand up to a challenge, use a proper e-signature provider that verifies identity and keeps a signing record. This tool suits informal forms, internal paperwork and documents where a visible mark is all that is needed.
Position is measured as a percentage: across is the distance from the left edge, down is the distance from the top edge. Width is a share of the page width, and the height follows automatically.
How it works in plain English
Start by choosing how you want to sign. Drawing lets you use a mouse or a finger on a touchscreen to write naturally, typing turns your name into a cursive-style font, and uploading accepts a PNG or JPG of a signature you already have, such as a photo of one written on paper with a plain background.
Once a signature is created, it appears as a movable, resizable box that you drag onto the page you choose. You can nudge it into position over a signature line, scale it to a natural size, and adjust it again before finalising, so it looks like it belongs on the page rather than being pasted on crookedly.
Everything happens locally using your browser's own processing power. The PDF you open is read directly on your device, the signature image is merged into the page there, and the finished file is handed back to you as a download. Nothing is transmitted to a server or kept afterwards, so once you close the tab there is no copy left anywhere. It is worth being clear about what this produces: a visual mark that looks like a signature, not a cryptographically verified signature with an identity check, a timestamped audit trail, or a tamper-evident certificate. For contracts, loan documents, or anything that might need to hold up as proof of consent, a dedicated e-signature service that verifies identity and logs the signing event is the appropriate tool, not this one.
Worked example
Someone needs to initial a three-page rental inspection checklist and return it the same day. They open the PDF in the tool, type their name, and the tool renders it in a flowing script font. They drag the signature onto the bottom of page one, resize it to match the blank line, and repeat the placement on pages two and three using the same signature.
Satisfied with the placement, they download the signed copy and email it back. The whole process takes under a minute and never involves uploading the document anywhere. Because this is a visual placement rather than a verified signature, if the checklist were later disputed there would be no built-in proof of who signed it or when.
Visual signature placement versus a certified e-signature service
| Feature | This tool | Certified e-signature service |
|---|---|---|
| Places a signature image on a page | Yes | Yes |
| Identity verification of the signer | No | Often, via email/SMS or ID check |
| Signing audit trail / timestamp log | No | Yes |
| Tamper-evident seal on the finished file | No | Yes |
| Works entirely offline in the browser | Yes | No, requires their servers |
| Suitable for legally binding agreements | Not recommended | Yes |

Frequently asked questions
Is the signature I create here legally binding?
Not on its own. This tool places an image of a signature onto the page, which is fine for informal documents, internal forms, or personal records. It does not verify your identity, log when or how the document was signed, or seal the file against tampering. For contracts or anything that might need to be enforced, use a proper e-signature service instead.
Can I upload a photo of my handwritten signature?
Yes. A PNG or JPG works best if the background is plain and the signature itself is dark and clear, since that makes it easier to see against the page. The tool places the image as-is, so cropping it closely around the signature beforehand usually gives a neater result once it's resized on the document.
Does the PDF get uploaded to a server to add the signature?
No. The document is opened and processed entirely inside your browser using your device's own resources. The signature is merged into the page locally, and the finished file is generated for download without ever being sent anywhere. Closing the tab clears everything, and no copy of your document or signature is retained.
Can I sign multiple pages with the same signature?
Yes. Once you've created a signature by drawing, typing, or uploading it, you can place it on more than one page in the same document, repositioning and resizing each placement independently. This is useful for multi-page agreements that require initials on every page plus a full signature at the end.
What file type do I get back after signing?
You get back a standard PDF with the signature image embedded directly into the chosen pages, so it opens and prints normally in any PDF reader. It is a regular file, not a special signed format, which means it can be shared, saved, or printed the same way as the original document.
