Digital Signatures vs. Electronic Stamps

While often used interchangeably, there are technical nuances in how we handle signs: 1. Appearance Streams: When you place a signature, we create a new XObject stream that represents the visual mark, ensuring it remains sharp at any zoom level. 2. Integrity Preservation: Our signing process is designed to be non-destructive, meaning the underlying text of the contract remains searchable and unaltered. 3. ISO Compliance: We follow the PDF/A and standard PDF specs for annotations, ensuring your signed document is readable by any legal or government entity.

Frequently Asked Questions about PDF Signing

Helping you master the art of digital signing.

Are electronic signatures legally binding?
In most countries, and for most ordinary commercial agreements, a visual electronic signature is widely recognised. What this tool produces is a simple electronic signature: a drawing embedded in the page, with no certificate and no qualified seal. For anything that demands a qualified signature under eIDAS, or a notarised document, you need a certified provider, not this.
Can I add multiple signatures to one document?
Yes, our tool allows you to place multiple signature blocks if the document requires several parties to sign.
Can I use this on my phone?
Yes! Use your finger or a stylus directly on your mobile screen for an experience that feels like signing real paper.
Will my signature look pixelated?
No, if you draw or type it, we use vector-based rendering to ensure it stays perfectly sharp.
Is it safe to sign my sensitive contracts here?
The question does not arise the way it does elsewhere: the contract never leaves your machine. pdf.js draws the page in the tab, pdf-lib embeds the signature in the tab, and the signed file lands straight on your disk. No upload, so no copy of ours and nothing to delete.
