PDF files often contain more than meets the eye. Beyond visible content, they can include metadata, JavaScript, annotations, and other hidden elements that might compromise security or inflate file sizes. Whether you’re preparing documents for distribution or simply managing sensitive information, it’s essential to sanitize, optimize, compress, and secure your PDFs effectively.
This guide explores how to handle these tasks using VeryPDF DRM Protector, a powerful solution offering robust security features and efficient PDF management. Try it for free online at VeryPDF DRM Protector.
Why Remove PDF Metadata, JavaScript, and Hidden Information?
Every PDF file contains metadata that reveals information about the document’s creator, modification history, and more. Hidden elements like JavaScript, annotations, blank pages, and attachments can also carry sensitive information or pose security risks. By sanitizing your PDFs, you can:
- Protect confidential data.
- Reduce file size for better performance.
- Enhance security by removing potential vulnerabilities.
