How to Sign a PDF
Printing a document just to sign it, then scanning it back in, is a waste of time and paper. Signing a PDF electronically lets you add your signature to contracts, forms and agreements directly on screen and send them straight back — no printer, no scanner, no delay. PDFOrca lets you place your signature onto a PDF and download the signed file ready to return.
You can position your signature exactly where it belongs — on the signature line, next to your initials, or across a form field — and save it into the document. The result is a clean, signed PDF that looks the way a returned agreement should.
When it saves the day
- Employment and rental contracts that need a quick signature and return.
- Consent and permission forms for school, medical or travel purposes.
- Business agreements and quotes you want to approve without printing.
- Any form that says "sign and send back" when you're working remotely.
Making your signed document look right
Place your signature so it sits naturally on the line rather than floating over the text, and keep it at a sensible size. Once you've signed, it's often worth protecting the file so the signature can't easily be moved — you can lock the finished document with a password using Protect PDF. For agreements with strict legal requirements, check whether the recipient needs a certified digital signature, which is a distinct, identity-verified technology.

If the form arrived as several files, merge them into one before signing. Need to sign only the last page of a long contract? Pull it out with Extract Pages first. And once signed, compress the PDF if it's too large to email back comfortably.
Frequently Asked Questions
How do I add my signature to the PDF?
Upload the document, place your signature where it needs to go on the page, and download the signed file. You can position it precisely on the signature line before saving.
Is an electronic signature legally valid?
In many everyday situations an electronic signature is widely accepted, but requirements vary by country and document type. For agreements with strict legal standards, confirm whether the recipient requires a certified, identity-verified digital signature.
Can I stop my signature from being moved afterwards?
Yes. After signing, lock the document with a password using our Protect PDF tool so the file can't be easily altered by the recipient.
Do I need to print anything?
No. The whole point is to avoid printing and scanning — you sign on screen and download a ready-to-send signed PDF.
Is the signature legally binding?
PDFOrca adds a visual signature image to your PDF. For legal validity, check your jurisdiction's requirements — many accept electronic signatures, but some contexts require qualified digital certificates.
