Sign PDF
Add your signature to a PDF. Draw it with a mouse or finger, or upload a picture of your signature, place it on the page, and download the signed file. It never leaves your device.
Step by step
How to sign a PDF
You can draw a signature or upload one, place it, and save it for next time.
Open a page and choose Sign
Open the page in the large preview and choose Sign to bring up your signatures.
Draw or upload
Draw your signature, or upload a photo of it. pdf2kit clears the white background so it sits cleanly on the page.
Place and download
Drop the signature where you want, resize it, then download the signed PDF.
Why pdf2kit
Sign documents without printing or uploading
Signing usually means a contract or form you would rather not send to an online service. pdf2kit adds your signature on your own device, so the document is never uploaded. Save a signature once and reuse it any time. It is free, with no account and no watermark.
FAQ
Signing PDFs: common questions
How do I add my signature to a PDF?
Draw it with your mouse or finger, or upload a picture of your signature. pdf2kit removes the white background so only the ink shows on the page.
Can I save my signature for next time?
Yes. Saved signatures stay on your device and can be reused on any document. They are never uploaded.
Can I sign on my phone?
Yes. Draw with your finger, place the signature, and download the signed file, all in the same page.
Is a signature added this way legally valid?
For everyday agreements a drawn or uploaded signature is widely accepted. For regulated or high-value contracts, check whether a qualified digital signature is required in your country.
Are my documents uploaded when I sign them?
No. Signing happens on your device. The document is never sent to a server.
