Frequently asked questions

Why remove JavaScript?

PDF JavaScript can contain malware. Removing it eliminates this security risk.

Will removing JavaScript break my PDF?

Most PDFs don't use JavaScript. If your PDF has JS-based form validation or calculations, those features will stop working after removal.

How do I know if my PDF has JavaScript?

Upload your PDF and the tool will detect and strip any embedded JavaScript. The PDF Info tool can also report whether JavaScript is present.

Is this the same as sanitizing?

Sanitizing is more comprehensive — it removes JavaScript plus metadata, attachments, and hidden data. This tool focuses only on JavaScript removal.
