About Sign PDF

Sign PDF lets you add your signature to any PDF without creating an account or uploading the document anywhere. Draw your signature with a mouse, finger, or stylus; type your name in a handwriting style; or upload a photo of your real signature — then click the exact spot on the page where it belongs, drag it into position, and resize it.

Everything happens in your browser. The PDF, your signature, and the signed result never touch a server — there is nothing to delete afterward because nothing was ever uploaded. That matters for the documents people actually sign: contracts, leases, offer letters, and medical or financial forms.

This is a visual signature (an image flattened into the page), the same kind most online "fill & sign" tools produce. It is not a cryptographic digital certificate — if a recipient requires certificate-based signing, they will tell you explicitly.

How it works

  1. Create your signatureDraw it on the signature pad, type your name and pick a handwriting style, or upload a photo of your signature on paper (the white background is removed automatically).
  2. Place it on the pageClick where the signature belongs, then drag to fine-tune and resize from the corner handle. Add it to one page or every page, and stamp the date too.
  3. Download the signed PDFThe signature is flattened into the document in your browser and the signed file downloads instantly.

When to use Sign PDF

Signing a contract or lease without printing
The classic print–sign–scan loop exists only to get ink onto paper. Draw your signature once, place it on the signature line, and send the PDF back in under a minute.
Sensitive documents that should not be uploaded
Offer letters, medical forms, and financial agreements are exactly the documents you least want sitting on a stranger’s server. Here the file never leaves your machine.
Initialing every page of an agreement
Create your initials as a second signature, place them once, and use "Apply to all pages" to stamp every page in one click.

Frequently asked questions

Is this a legally binding signature?
In many jurisdictions (e.g. under the US ESIGN Act or eIDAS in the EU), an image signature placed with intent to sign can be legally effective for most everyday agreements. Whether it is sufficient depends on the document type and your jurisdiction — for high-stakes documents, check what the recipient requires.
Is my document uploaded to your servers?
No. The PDF is opened, previewed, signed, and saved entirely inside your browser. Neither the document nor your signature is transmitted anywhere.
Can I sign on my phone or tablet?
Yes — the signature pad works with touch and stylus input, and placements can be dragged and resized with a finger.
Is this a digital certificate signature?
No — it places a visual signature image, the same as the "fill & sign" feature in most PDF tools. It does not attach a cryptographic certificate. Certificate-based signing is a different workflow that requires an issued signing certificate.
Can I reuse my signature next time?
Signatures are kept in memory for the current session only and are gone when you close the tab — by design, since storing signatures would be a privacy liability. Recreating one takes a few seconds.
