Free online PDF tool
Detect JavaScript and actions in a PDF
PDFs can carry JavaScript, OpenAction entries and Additional Actions that run when the document is opened or interacted with. These are useful for interactive forms but also a common vector for malicious documents. PdfWiseAI scans a PDF and lists every script and risky action it finds.

Professional use cases
When a private browser-based workflow helps
This workflow is useful for legal teams assembling exhibits, finance staff preparing statements or tax records, healthcare offices organizing administrative documents, and anyone handling files that should not be copied to an unnecessary conversion server.
PdfWiseAI creates a separate result and leaves the source unchanged. Review page order, image quality, visible content and the output filename before sharing the generated file.
Privacy verification checklist
Check the workflow before using sensitive documents
- Use a harmless sample file first and confirm the expected output.
- Prefer local transformations when no AI analysis is needed.
- Follow your organization’s security, legal and records policies.
- Keep originals until the generated file has been reviewed.
Local processing reduces document transfer, but it is not a certification of compliance with HIPAA, attorney-client duties or another regulatory framework.
