Frequently Asked Questions

1What does sanitizing remove?

Hidden data, embedded JavaScript, metadata, attached files, and comments. The visible content remains unchanged.

2When should I sanitize a PDF?

Before sharing externally — especially legal documents, contracts, or files that may contain hidden tracking data.

3Does sanitizing change the visible content?

No. Only hidden and non-visible elements are removed. Text, images, and formatting remain identical.

4Is sanitizing the same as redacting?

No. Sanitizing removes hidden data layers. Redacting removes visible content. For complete privacy, use both tools.

Why Use ZiaSign's Sanitize PDF Tool?

ZiaSign's PDF sanitizer removes all hidden data, embedded JavaScript, metadata, attached files, and comments from your document. The visible content remains untouched, but all potentially sensitive hidden data is stripped. Essential before sharing documents externally or publishing online.
