PDF Security Best Practices: Protect Your Documents
PDFs can carry hidden risks. Here's how to share documents safely without compromising security.
1. Strip Hidden Metadata
Before sharing any PDF externally, use Remove Metadata to clear author names, company info, document dates, and editing history.
2. Remove Embedded Content
PDFs can contain JavaScript, embedded files, and external links. The %%Sanitize PDF tool|/tools/sanitize-pdf%% strips these elements, reducing security risks.
3. Flatten Interactive Forms
Fillable forms can be altered after you send them. %%Flatten PDF|/tools/flatten-pdf%% makes form content permanent.
4. Remove Annotations and Comments
Review comments and markup often contain sensitive feedback. Use %%Remove Annotations|/tools/remove-annotations%% for a clean copy.
5. Add Watermarks for Sensitive Documents
Mark documents as 'Confidential' or 'Draft' with %%Watermark PDF|/tools/watermark-pdf%% to prevent casual sharing.
6. Process Locally
ViePDF processes all files in your browser. Your sensitive documents never leave your device — the most important security measure of all.
