Frequently Asked Questions

What does PDF metadata contain?
Typically the name of the document's author, the software used, and creation/modification dates.
Why should I remove comments?
Comments or annotations added to a PDF can remain visible to others when you share the document, even unintentionally.
Does cleaning the PDF change its visible content or layout?
No, only the document's info fields (title, author, subject, keywords, producer, creator) and, if you choose, its annotations are cleared — the pages, text and formatting are untouched.
Is my PDF uploaded to a server to be processed?
No, reading and rewriting the metadata both happen locally in your browser; the file never leaves your device.
Are annotations removed automatically?
Removal is optional but on by default — the checkbox is pre-checked whenever annotations are found, so uncheck it first if you want to keep the markups and only clear the metadata fields.
