How to use the Sign PDF tool
- Choose the PDF you need to sign, or drag it onto the drop area. The first page opens in the editor.
- Create your signature: draw it on the pad, type your name and pick a style, or upload a photo or scan of it.
- Your signature lands on the current page. Drag it onto the signature line and pull the round handle to make it bigger or smaller. On a phone you can tap the page to move it.
- Add the date and your initials if the document asks for them. Select an item and use Copy to every page to initial each page in one step.
- Press Sign and download PDF. Check the preview, then save the file. Tick Remember on this device first if you want the signature ready next time.
Worked example: signing a three-page lease
A tenant receives a 3-page lease as a PDF. They draw a signature on the pad and press Use this signature, which places it on page 1. They move to page 3 with the pager, add the signature again and drag it onto the tenant line. Then they add the date in the MM/DD/YYYY format, which reads 10/24/2026 on October 24, 2026, and add initials, which become J.D. for a typed name of Jane Doe. Using Copy to every page on the initials puts them on pages 1, 2 and 3. The download has 3 pages, the same as the original, and the lease text is still selectable because nothing was flattened into an image.
Three ways to make your signature
Draw works best on a phone or tablet with a finger or stylus. Strokes are smoothed as you write and saved as a vector drawing, so the signature stays crisp at any zoom level instead of turning blocky. Type sets your name in Times Italic, Times Bold Italic or plain Helvetica. These are standard fonts every PDF viewer already has, so the result is sharp text. We do not bundle handwriting fonts; if you want a handwritten look, draw or upload instead. Upload takes a photo or scan of a signature on paper. The white paper background can be made transparent so the ink sits naturally on the line.
Is a signature added this way legally valid?
In many countries, including the US under the ESIGN Act and the EU under eIDAS, a simple electronic signature like this one is accepted for everyday agreements such as leases, permission slips and offer letters. Some documents need more, for example a notarized deed or a filing that requires a certificate-based digital signature from an approved provider. This tool does not add a cryptographic certificate and does not lock the file against later changes. If you are unsure what a document requires, ask the person who sent it.
Your files stay on your device
The PDF and your signature are processed by code running in this page. Nothing is sent to a server: the signature is drawn into the file inside a background worker of your own browser. If you tick Remember on this device, the signature is kept in this browser's local storage only, and unticking the box deletes it.
Frequently asked questions
Is it really free, with no watermark?
Yes. There is no account, no trial and no watermark. The only thing added to your PDF is what you place on it.
Can I sign on my phone?
Yes. Draw with your finger on the signature pad, then drag the signature into place or tap the page to move it there. Use the round handle to resize it.
Does signing change the rest of the document?
No. Your signature, date and initials are drawn on top of the existing pages. The original text stays selectable and searchable, and the page count does not change.
Where is my saved signature kept?
Only in this browser, and only if you tick Remember on this device. It is never uploaded. Untick the box, or clear the site data in your browser, to delete it.
Is this a digital signature?
It is a simple electronic signature: a visible signature on the page. It is not a certificate-based digital signature, which needs an identity certificate from a trust service provider.
Can I sign a password-protected PDF?
Not directly. Open it in your PDF viewer, enter the password and save an unprotected copy, then sign that copy here.
