Signature fields with Microsoft Word

If you want to insert form fields (signature fields, text fields, checkboxes etc.) when creating Word documents, inSign offers two options:
Install our free add-in for Microsoft Word and simply drag and drop form fields into your document.
“SIG tags” are special text abbreviations for form fields that you can insert invisibly into your document at the appropriate places.

Word Add-in


Please open the required Word document and install the inSign Word Add-in by clicking “Insert” – “Get Add-ins”. Then enter “inSign” into the search field and click in the field “inSign for Word” the “Add” button.

The Word Add-in allows you to automatically convert Word documents to PDF documents. They can then be signed. Please follow this procedure: Please open your Word document as usual. On the “Home” tab you will find the inSign icon to the right. Clicking this allows you to log into using your inSign user credentials. If needs be, missing text and signature fields can be inserted into Word instantly. Click “Done” and the document automatically converts into PDF and initiates an inSign process. Then proceed as usual.
Open Add-in


Right-click the inSign Word Add-in under the “Start” tab. Click “Remove Add-in” on the context menu. Alternatively, you can also find the Add-in under “Insert” – “Get Add-ins” – “My Add-ins”.

Text blocks (SIG-Tags)

inSign SIG-tags are specially formatted text that can be placed at the desired positions in the contents of your document. The tag is then automatically converted into a form field by inSign when the document is uploaded.
A SIG tag looks like this: ##SIG{}
If you insert this text into your Word document, a mandatory signature field will appear at the corresponding position in inSign.
Proceed as follows:
  • 1. Insert the text “##SIG{}” (without the quotation marks) into your Word document at the position where a mandatory signature field should be placed.
  • 2. Change the text colour of the SIG tag to white so that the text is invisible later. You can omit this step for test purposes.
  • 3. Save your Word document as a PDF file.
  • 4. Upload the PDF to inSign.
  • 5. The corresponding signature field now appears in the location of the SIG tag.

  • Note: If you have installed the Word Add-in, steps 3 and 4 are omitted by clicking the Done button.
If you want to specify the properties of the form field more precisely, you can add the following additional parameters inside the curly brackets:
Text fieldtype:'text'Form field is an input field for free text
Photo fieldtype:'image'Form field is a photo or image
Checkboxtype:'checkbox'Tick box
Mandatory fieldrequired:trueForm field is mandatory
Optional fieldrequired:falseForm field is optional
Widew:'5.4cm'Width of the form field
Heighth:'7.0mm'Height of the form field
Horizontal shiftx:'-5.6mm'A negative value moves the field to the left, a positive value to the right.
Vertical shifty:'-12.2mm'A negative value moves the field up, a positive value moves it down.
If several properties are to be set, they must be separated from each other with a comma.

Hints & Tips

  • • Signature fields correspond to the handwritten advanced electronic signature (AES)
  • • Size specifications can be provided in mm or cm
  • • Parameters are case-sensitive, otherwise the SIG tag will not be recognized
  • • Values with fractions must be written with a period “.”
  • • SIG tags can no longer be edited in inSign
  • • SIG tags can also be used in all other documents such as Excel, PowerPoint, Libre Office, etc.
