E-Sign Basics for Application Forms and PDFs

Updated November 13, 2026 · 2 min read

The word “e-sign” is used for several different things, and confusing them can lead to a rejected form. Here is a plain-language guide.

Three kinds of signing

  1. A picture of your handwritten signature. This is what most exam and job forms need. You upload a small image of your signature.
  2. A signature placed on a PDF. You draw or type your signature on a document, such as a declaration or an application letter.
  3. An official e-sign service. This uses a verified identity, often with an OTP, and is done through an authorised provider. It is a formal process with its own rules.

Which one you need depends entirely on the form or organisation. Read the notice.

When a form asks for a signature image

Sign with a dark pen on white paper, or draw one on screen. The signature maker lets you draw or type your signature and save a form-ready JPG at a size and pixel dimension you choose. Many portals check the size range, so check the notice.

When you must sign a PDF

For a declaration, consent letter or application, the sign PDF tool lets you place a signature on a page. You can then download the signed copy. Keep the original file in case you need another version.

If you need to write a declaration first, the letter and declaration maker offers general templates you can edit and download as a PDF. It is not legal advice.

What a drawn signature does not do

A signature added with a general tool is a visual mark. It does not make the document legally verified through an official e-sign service, and it does not prove who signed it. If an organisation requires an official e-sign, use the service it names. Some organisations accept only a wet signature on paper that you scan.

Tips for a good signature

  • Use the same style you use on your official documents.
  • Keep it clear and not too small.
  • Avoid a signature that is faint or thin.
  • Do not use someone else’s signature or sign for another person.

Safety

Do not share OTPs with others. Sign only documents you have read. Keep a copy of every signed document you submit.

Before you submit

  1. Zoom in and check the signature is readable.
  2. Confirm the format and size match the notice.
  3. Check the date and name on the document.
