Frequently Asked Questions

Are visual signatures legally binding?

In most countries (including the US ESIGN Act, EU eIDAS regulation for basic electronic signatures, and Pakistani Electronic Transactions Ordinance), visual electronic signatures are legally valid for standard commercial contracts, invoices, and internal approvals.

Is my signature saved securely?

Yes. When you choose to save your signature or initials, it is stored strictly inside your browser's private local storage on your own computer. Nothing is ever sent to or stored on our servers.

Can I edit my initials and add custom text?

Yes. You can customize your initials to any letters and choose between square badge, circle badge, or plain text. You can also stamp custom names, job titles, and approval remarks.

Signing PDFs Without Printing Them

The four kinds of e-signature

Not all signatures on a PDF are the same thing, and knowing which one you're applying avoids awkward conversations later:

Type	What it is	Best for
Drawn signature	Your signature drawn with mouse, finger or stylus	Everyday contracts and forms
Typed signature	Your name in a script font	Internal approvals, low-stakes sign-offs
Image signature	A photo/scan of your wet-ink signature	Matching how your signature looks on paper
Certificate-based digital signature	Cryptographic identity certificate	High-stakes legal and government filings

Are e-signatures legally valid?

In most jurisdictions, yes for ordinary agreements — Pakistan's Electronic Transactions Ordinance (2002), the US ESIGN Act and the EU's eIDAS all recognize electronic signatures. Practical caution still applies: certain documents (property transfers, some court filings) may require wet ink or certified digital signatures, and requirements vary by country and document type — when the stakes are high, confirm what the receiving party accepts. Whatever you sign, keep your own dated copy.

A sensible signing workflow

Assemble the full document first — merge annexes before signing so nobody can claim pages were added afterwards. Sign, then optionally password-protect the signed copy or stamp it with a watermark like “Executed copy”. Your file is processed in your browser — an unsigned contract never touches a server here.
