A .docx file is editable by design. If you sign a Word document directly, anyone with Microsoft Word can alter the document text after your signature is placed — making your signature legally meaningless. Converting to PDF locks the content and makes any tampering visually detectable.
If you need to sign a Word document, you have several options. Here is a complete overview of every method and when to use each one.
Go to Insert → Signature Line. This adds a formal placeholder with the signer's name and title. Best for preparing documents for print-and-sign. Requires a digital certificate for digital signing.
Use the Draw tab in Word to freehand-sketch your signature using a mouse, trackpad, or stylus. Quick and informal — but the .docx file remains editable.
Go to Insert → Pictures → This Device and upload a PNG of your scanned signature. Use Wrap Text → In Front of Text to position it freely over the line.
Save the Word doc as PDF, then use MyDigitSign to draw, type, or upload your signature and place it on any page. The most professional and legally secure approach.
Most tools that let you sign Word documents either charge a monthly fee, upload your file to their servers, or add a watermark to your free download. MyDigitSign does none of those.
