Sanitize PDF

Sanitize PDF strips all hidden data from a PDF: metadata, embedded scripts, JavaScript actions, form data, comments, thumbnails, and other non-visible elements. The result is a clean, minimal PDF that contains only the visible page content — ideal for sharing documents where hidden data could pose a privacy or security risk. Sanitize PDF sits in FilePilot's pdf tools collection, so it is easy to move between this task and nearby tools such as Free Online PDF Tools, Free Online Image Tools, Merge PDFs. It is useful when you need to clean documents before sharing outside your organization; remove hidden metadata that could reveal editing history or author details; strip embedded scripts for security before opening untrusted pdfs; prepare documents for public release by removing all non-visible data. The workflow is straightforward: upload the pdf you want to sanitize; the tool identifies and removes all hidden data automatically; download the sanitized pdf containing only visible content. The work happens locally in your browser using client-side processing, which keeps your files on your device and gives crawlers a clear plain-text description of what this page does before the interactive app loads.

How it works

  1. Upload the PDF you want to sanitize.
  2. The tool identifies and removes all hidden data automatically.
  3. Download the sanitized PDF containing only visible content.

Frequently asked questions

  • What does sanitizing a PDF do?

    It removes all metadata (author, creator, keywords), flattens form fields, and re-serializes the PDF structure to remove hidden data.

  • Will my file content be changed?

    No. Only metadata and interactive elements are removed. The visible page content remains unchanged.

  • Is my file uploaded?

    No. Everything runs locally in your browser.
