Frequently Asked Questions
Q: Is this a legally binding electronic signature?
For simple electronic signatures, this tool meets basic requirements in many jurisdictions. For legally binding contracts requiring advanced or qualified electronic signatures (EU eIDAS, US ESIGN Act), consult a legal professional about your specific requirements.
Q: Can I sign Arabic documents?
Yes. Our tool uses browser-native canvas text rendering which correctly handles Arabic character shaping, right-to-left text direction, and ligatures — unlike basic PDF text embedding which often breaks Arabic scripts.
Q: Is my PDF uploaded to your server?
No. Your PDF never leaves your browser. The signing process runs entirely in your browser using the pdf-lib WebAssembly library. Zero data is transmitted to any server.
Q: What PDF types are supported?
Standard PDFs including scanned documents, forms, and multi-page contracts. Password-protected PDFs cannot be signed without first removing the password protection.
Q: Can I place my signature on specific pages only?
Yes. You can place your signature on the first page, last page, all pages, or enter specific page numbers separated by commas for precise placement.
Q: Does my signature look professional?
Typed signatures are rendered at 4x resolution using high-DPI canvas scaling, ensuring a crisp, professional appearance at any zoom level. Drawn signatures capture your freehand input at full resolution.
