Why this matters
A strict default is easier to trust in high-risk workflows than partial filtering that can miss edge cases.
Safe default steps
- Assume interactive PDF elements are risky by default.
- Scrub first, then re-check whether content meaning is intact.
- If links are needed, add them later in a lower-risk copy.
Common mistakes
- Expecting hyperlink behavior to remain unchanged.
- Re-introducing form fields before sharing sensitive copies.
- Confusing convenience with safety.
Limits
This default prioritizes safety over feature retention. Future modes may allow controlled toggles with warnings.
