How can I virtually sign a PDF file?

Sign your PDF with MSB Docs. Start by logging in to your MSB Docs account and uploading the relevant document, then use the editor tools to add or remove text and dropdowns as desired. When you’re ready, click on My Signature to insert your electronic signature; adjust its size accordingly and save it for future documents. If any changes are needed at a later date, simply replace the eSignature with a new one.
