Sign a PDF electronically

Printing a document just to sign it and scan it back is slow and wasteful. eSign PDF lets you add your signature to a contract, form or agreement digitally, so you can return signed paperwork in minutes from any device. It is perfect for offer letters, rental agreements, consent forms and any document that needs your sign-off without a trip to the printer.

A clean electronic signature also looks more professional than a faint photocopied scan, and keeps the document entirely digital from start to finish.

Placing your signature

Upload the PDF, draw or place your signature where it belongs, position it precisely on the signature line, and download the finished document. The signature becomes part of the page, so it travels with the file wherever it goes.

Take a moment over placement. A signature overlapping the printed line, spilling into the adjacent date field, or sitting on the wrong party's line is the kind of thing that gets a document sent back. Signing several pages of the same agreement is common — initialling each page is a frequent requirement — so check you have covered every place the document asks for a mark, not just the final one.

Where a date is required alongside the signature, fill it in as part of the same pass rather than leaving it blank for someone else to complete.

What makes an electronic signature binding

In most jurisdictions — under frameworks such as eIDAS in the EU and the ESIGN Act in the US — a contract is not invalid merely because it was signed electronically. What matters is evidence of intent to sign and agreement to the terms, not the mechanism used to produce the mark.

That said, not all electronic signatures are equivalent. A drawn image of a signature demonstrates intent but carries no cryptographic proof of who applied it or whether the document changed afterwards. A digital signature, which uses a certificate to bind the signature to the document's contents, does provide that proof and will visibly break if the file is altered.

For everyday agreements — consent forms, internal sign-offs, straightforward commercial arrangements — a drawn signature is normal and widely accepted. For high-value contracts, property transactions, wills or anything with a regulatory requirement for a qualified signature, check what is actually required before relying on one. This is general information rather than legal advice, and the specifics vary by country and document type.

Protecting the signed document

Once signed, flatten the document if you can, so the signature and any filled fields become part of the page rather than editable layers. Live form fields in a signed agreement can be altered by whoever receives it, which is rarely what either party intends.

Be careful with the signature image itself. A clean cut-out of your handwritten signature is reusable by anyone who obtains it, so avoid emailing it as a standalone image file and avoid leaving it in shared folders. Signing directly onto the document, rather than circulating the signature separately, keeps it attached to the context it belongs to.

Keep the signed file. The signed PDF is your record of the agreement, and it is worth storing somewhere durable rather than leaving it in a downloads folder.

Signed on your own device

Signing happens in your browser, so neither the agreement nor your signature is uploaded. Documents at the signing stage are among the most sensitive things people handle — offer letters, tenancy agreements, settlements, consent forms — and this keeps both the contract and the signature that binds you to it on your own machine.
