Sanitizing the /Info Dictionary
Editing metadata involves overwriting the string objects associated with keys like /Title, /Author, and /Subject in the document's Info dictionary. If the document uses XMP metadata, that XML stream must also be parsed and modified.
Our client-side editor allows you to selectively blank out these fields, rewriting the PDF safely so that forensic analysis won't reveal your original details.
Technical Details
| Field | Recommended Action for Privacy | Impact |
|---|---|---|
| Author | Clear or use pseudonym | Prevents identity leak |
| Title | Clear or use descriptive name | Affects window title in readers |
| Subject | Clear | None |
| Keywords | Clear | None |
