Update Source PDF allows you to change the original PDF of your SeamlessDoc. This is perfect if any changes are made to the PDF, so that you can update your SeamlessDoc to reflect these changes, while still maintaining all of your fields.
To update the source PDF for a SeamlessDoc:
Select File, then Update Source PDF. A pop up window will appear letting you know about all the conditions along with updating source PDF. The most important thing to know is that the PDF you are uploading must be the same page length as the original PDF that you converted.
2. Once you select Continue, you will then be brought to a screen where you can upload the PDF that you'd like to replace.
