Frequently Asked Questions
Why do custom dynamic stamps fail to rotate properly in PDFs?
This usually occurs due to software bugs or conflicts within the PDF viewer's JavaScript engine, causing the viewer to fail at rendering the dynamic code properly upon placement.
Can I use standard image formats for PDF stamps instead of JavaScript?
Yes, standard image formats like PNG, JPG, or transparent GIFs can be used to create static custom stamps. They are generally much more stable and less prone to rotation errors compared to dynamic JavaScript stamps.
Will updating my PDF software delete my custom stamps?
Generally, software updates patch system files and leave user-generated content like custom stamps intact. However, locating your stamp directory and backing it up beforehand is always a safe practice.
Where are Acrobat custom stamps stored on a Windows PC?
Custom stamps are typically stored within the user profile directory under AppData > Roaming > Adobe > Acrobat > [Version] > Stamps.
