Electronic Signatures vs. Digital Signatures
It's important to understand the difference between electronic and digital signatures. Our tool creates electronic signatures, which are visual representations of your signature on a document. These are widely accepted for most everyday documents and internal business purposes.
For legally binding documents that require cryptographic verification (like certain government filings or high-value contracts), you may need a qualified digital signature that complies with regulations such as eIDAS (Europe), ESIGN Act, or UETA (USA). Our tool clearly notifies you of this distinction before processing your document.
Legal Disclaimer
This tool provides a convenient way to add visual signatures to PDF documents. For legally binding agreements, please consult with a legal professional to determine if additional verification or certified electronic signature services are required for your specific use case.
Frequently Asked Questions
Is my PDF uploaded to a server?
No. Your PDF is processed entirely in your web browser. The file never leaves your device, ensuring complete privacy and security.
Can I add multiple signatures to one document?
Yes! You can add as many signatures as you need, on any page of the document. Each signature can be individually positioned, resized, and removed.
What signature formats are supported?
You can draw a signature (works with mouse or touchscreen), type your name, or upload an image file (PNG, JPG). For best results with uploaded images, use a PNG with a transparent background.
Is there a file size limit?
Since processing happens in your browser, the limit depends on your device's memory. Most devices can handle PDFs up to 50-100MB without issues.
Does this work on mobile devices?
Yes! Our signature tool works on smartphones and tablets. Drawing signatures with your finger on a touchscreen provides a natural signing experience.
