How to Sign a PDF for Official Documents — Free
Most forms just need your signature image or typed name — you do not need expensive software.
Quick answer: Add your signature (typed, drawn, or an image) to the PDF in your browser, then save and send it.
Real-world use — what we verified
We signed a ten-page lease by placing a typed signature on the last page; the file stayed local and the recipient accepted it as a normal signed PDF.
Honest note: This adds a visible signature, not a cryptographic digital-ID signature. For court-grade or certified e-signatures, use a qualified e-sign provider.
Step-by-step
- Open the sign tool and add your PDF (stays in your browser).
- Choose typed, drawn, or image signature.
- Place it on the correct page.
- Save and download the signed PDF.
If it is still too big
- For legally certified signatures, use a qualified e-sign service instead.
- Add the signature to every page that requires it.
- Compress the final file if you must email it afterward.

FAQ
Is a browser signature legally valid?
A visible signature is fine for most routine forms; for certified/qualified e-signatures, use a licensed e-sign provider.
Does signing upload my document?
With an in-browser tool like this, the file is processed locally and never uploaded.
Can I add a signature image?
Yes — upload a picture of your signature and place it on the page.
