About Sign PDF
Add an electronic signature to a PDF document directly in your browser — draw, type, or upload your signature and place it exactly where the document needs signing.
The signature is applied as a visual annotation on the PDF pages you choose. This is practical for contracts, consent forms, approval sheets, and everyday paperwork where a formal qualified-signature workflow is not required. For documents with legal weight, check whether your jurisdiction or counterparty requires a certified digital signature instead of a drawn or typed mark. PDF structure, page order, text layers, embedded media and output quality can affect the result. Check page count, page order, readable text, important numbers and the final downloaded file before sharing it.
Primary objective: Places a typed signature-style mark on a chosen PDF page and creates a new copy.
Privacy assurance: This PDF operation is performed in the browser from the file you select; the workflow does not require uploading the document to ExpTool.

Frequently Asked Questions
Is a drawn PDF signature legally binding?
It depends on the jurisdiction, the document type, and what the parties agreed. Many everyday agreements accept electronic marks, but regulated or high-value documents may require a qualified digital signature with identity verification.
Can I sign multiple places in one document?
Yes. Place a signature instance on each page or field that requires one before downloading the finished file.
Does signing change the rest of the PDF?
The signature is added as an overlay; the original page content is preserved. Always review the final file before sending it.
Can the signature be removed afterward?
A drawn or typed signature placed this way is a visual mark, not cryptographic proof. Anyone with a PDF editor could alter it, so use certified signing workflows when tamper evidence matters.
What should I check before using the Sign PDF result?
Check page count, page order, readable text, important numbers and the final downloaded file before sharing it. PDF structure and embedded media can affect processing time and output size.
Does Sign PDF replace a professional or authoritative source?
No. Sign PDF is a practical utility. Where the result affects a regulated, financial, medical, legal or business decision, verify it against the appropriate authoritative source or qualified professional.
