Sign PDF Online Free
Create your signature by drawing, typing or uploading a photo of it, then place it on any PDF in seconds. Free, private and works on your phone.

Your files never leave your device. Electronic signatures are generally recognised in Nigeria, but some documents, such as wills, land and property documents and powers of attorney, may still need a handwritten signature, witnesses or notarisation. Only sign documents you are authorised to sign.

Your signature stays with you
Your signature and document are created and processed in your browser only. Nothing is stored or uploaded, so no one can reuse your signature.
Are electronic signatures valid in Nigeria?
Electronic signatures are generally recognised under the Evidence Act 2011 and the Cybercrimes Act 2015. Some documents are excluded, such as wills, birth and death certificates and court orders, so ask a lawyer about those.
Questions people often ask
Straight answers to the questions we hear most often.
Is it really free?
Yes. There is no sign-up, no watermark and no page limit, for personal or business documents.
Are my files uploaded anywhere?
No. The PDF is processed entirely in your browser, so the file never leaves your phone or computer.
Can I sign with my finger on a phone?
Yes. Choose Draw and sign on the pad with your finger or a stylus. You can also type your name and pick a handwriting style.
Can I use a photo of my real signature?
Yes. Sign on white paper, take a clear photo and choose Upload. The white background is removed automatically.
How do I sign several pages?
Scroll to the next page and click Add signature again, then choose Use my last signature.
Is a signed PDF legally binding?
Electronic signatures are generally accepted in Nigeria for business documents, but some documents have special rules. This tool is not legal advice.
