Practical guide
What to know before you start
Sign a PDF online with a visible electronic signature. Draw a handwritten signature, type your name in a signature style, or upload an existing signature image, then place and resize it on any page. This free PDF signer works locally with no signup or document uploads.
Create an electronic signature for your PDF
Draw with a mouse, touchscreen, stylus, or trackpad; type your name in a handwriting-style font; or choose a PNG, JPG, or WebP image you already use as a signature. The selected ink color is applied to drawn and typed signatures.
- Draw directly in the signature pad
- Choose from three typed signature styles
- Upload an existing signature image
- Transparent PNG images produce the cleanest result
Add a signature to any PDF page
A newly created signature is inserted in the center of the current page and retained in the signature list. Select any saved signer, add the signature to the current page, drag it onto the required signature line, or resize it from the lower-right handle.
- Keep multiple signers in one task
- Move and resize on the full-page preview
- Add multiple signatures to one page
- Reuse signatures across several pages
Electronic signature versus digital signature
The downloaded copy embeds each signature as visible page content. This is suitable when you need to sign a document yourself or place a handwritten signature on a form. It does not authenticate your identity with a digital certificate and is not a certificate-based digital signature.
- Visible signature is embedded in the output
- Original PDF remains unchanged
- Output pages are rebuilt for stable placement
- Existing certificate signatures and interactive annotations may not be preserved
Sign PDFs locally with no uploads
PDF rendering, signature creation, placement, and output generation happen in browser memory. KissPDF does not send the selected document or signature image to a document-processing server.
- No document upload
- No signup or watermark
- No server-side signature storage
- Close or reset the workspace to clear the current task
Frequently asked questions
Clear answers based on how this tool actually works.
How do I add a signature to a PDF?
Select the PDF, draw, type, or upload your signature, and click Create & add. Drag and resize it on the page, then download the signed PDF.
Can I fill and sign a PDF online?
Yes. If the form needs typed answers or check marks, use the Fill PDF Form tool first, download that copy, and then add your signature with this PDF signer.
Can I e-sign a PDF for free?
Yes. You can create and place a visible electronic signature without signup, a watermark, or a document upload.
Can I sign more than one PDF page?
Yes. Navigate between pages, select a saved signature, and add it to every page that needs it.
Can several people sign the same PDF?
Yes. Create and retain multiple signatures in the right-side signature list, then select the appropriate signer for each page or signature field.
Can I upload a signature image?
Yes. PNG, JPG, and WebP images are supported. A tightly cropped transparent PNG usually blends into the document most naturally.
Is this a certificate-based digital signature?
No. It adds a visible electronic signature but does not create a PAdES signature, trusted timestamp, certificate chain, or cryptographic identity verification.
Will the signed PDF be editable?
The signature placements become visible page content in the downloaded copy. The page is rebuilt, so review forms, links, annotations, and other interactive features before sending it.
Is my PDF or signature uploaded?
No. The PDF and signature are processed locally in your browser.
