Sign Offer Letters Online — Fast, Private, Legally Valid

Offer letters are time-sensitive. When a company extends a job offer, they typically expect a signed response within days — or sometimes within hours for competitive positions. When a business proposal has a deadline, every hour counts. The traditional process of printing the offer letter, signing it by hand, scanning the signed pages, and emailing the result introduces unnecessary delay and friction. If you are traveling, do not own a printer, or receive the offer after business hours, the delay can be significant enough to put the opportunity at risk.

SigPDF removes every barrier between receiving an offer and accepting it. Open the offer letter PDF in the editor above, create your signature by drawing it with your finger or mouse, place it on the signature line, add the date, and download the signed document. You can email the accepted offer back within minutes of receiving it — from your laptop, phone, or tablet, wherever you happen to be. No printer, no scanner, no software installation required.

Keep Your Compensation Details Private

Offer letters contain highly confidential information. A job offer letter typically includes your proposed salary, signing bonus, equity grant or stock options, benefits package, relocation allowance, start date, and reporting structure. A business proposal may contain pricing details, project scope, margins, and proprietary strategy. This is information you would never want a third party to access — yet uploading these documents to a cloud-based signing platform means exactly that.

SigPDF takes a fundamentally different approach. Your offer letter is processed entirely inside your browser using client-side JavaScript. The PDF file never leaves your device. It is not uploaded, not transmitted, and not stored on any remote server. Your salary, your equity details, and your entire compensation package stay completely private.

Legal Validity of Electronically Signed Offer Letters

Electronically signed offer letters are legally binding and enforceable under the major e-signature frameworks:

• ESIGN Act (United States): The ESIGN Act explicitly covers employment-related documents, including job offer letters. An electronic signature on an offer letter carries the same legal weight as an ink signature, and courts have consistently upheld this.
• eIDAS Regulation (European Union): A simple electronic signature — such as one created with SigPDF — cannot be denied legal effect solely because it is in electronic form (Article 25.1). This applies to offer letters across all EU and EEA member states.
• UK, Canada, Australia: Equivalent legislation in each jurisdiction recognizes electronic signatures on offer letters, including the UK Electronic Communications Act, Canadian PIPEDA, and Australian Electronic Transactions Act.

In practice, the overwhelming majority of employers now send and accept offer letters electronically. Signing your offer letter with SigPDF produces a standard signed PDF that any HR department or business partner will accept.

Print-Scan-Mail vs. SigPDF

The traditional offer letter signing process involves multiple steps and multiple pieces of equipment. You download the PDF, find a working printer, print the document (often two to four pages), sign the signature page by hand, scan all pages back into a single PDF, verify the scan is legible, and email it to the hiring manager or HR. If you are between apartments, traveling for work, or working from a co-working space without a scanner, this process can delay your response by a full day or more.

With SigPDF, the process is: open, sign, download. Done in under sixty seconds. You can accept a job offer from the back seat of a taxi on your phone if you need to. Speed matters when offers have deadlines, and SigPDF gives you the fastest possible turnaround.
