Questions about this tool
How does this tool work: Sign PDF?
Free, no sign-up, right in your browser. Open a PDF – the signature window opens automatically. Sign, choose “Place signature” and click the spot in the document. Adjust size, add the date and save.
Is a signature created this way legally valid?
This is a simple electronic signature (an inserted signature image). It is sufficient for many everyday documents but does not replace a qualified electronic signature where the law requires written form. If in doubt, ask the recipient.
What inputs, outputs and limits apply?
Input: One PDF and your signature (drawn, typed or image). Output: Signed PDF. Limits: Up to 100 MB per PDF and 500 pages in total. Password-protected PDFs are rejected; permission-protected PDFs are kept as images. Text editing works on real text layers, not on scans (no OCR). Changes invalidate digital signatures of the original file.
