How does the PDF malware scanner work?

Our scanner reads the internal structure of your PDF file locally and checks for known malicious patterns such as hidden JavaScript payloads, auto-execution tags (, ), and external launch commands that hackers use to distribute malware.

Do you upload my PDF to scan it?

No. Just like our other tools, the PDF virus scanner operates entirely inside your web browser. Your sensitive documents never leave your computer, ensuring absolute privacy.

Can a PDF file contain viruses?

Yes. PDF files can contain embedded executable code like JavaScript, which can be exploited by hackers to run malicious commands on your computer when you open the file in a vulnerable PDF reader.

What should I do if malware is detected?

If you receive a warning about hidden JavaScript or auto-actions in an unexpected document (especially from unknown senders), do not open the file with your desktop PDF reader. It is safer to delete it immediately.

About PDF Virus Scanner

Scan PDFs for Hidden Threats

PDF files can contain more than just text and images. Malicious PDFs may include embedded JavaScript, auto-launch actions, executable attachments, or exploit code targeting PDF reader vulnerabilities.

What We Check

The scanner analyzes your PDF's internal structure for:

JavaScript — code that runs automatically when the PDF opens
Auto-actions — OpenAction and AA (Additional Actions) that trigger on open, close, or print
Embedded files — executables or scripts hidden inside the PDF
Known exploits — patterns matching common PDF vulnerability exploits
Suspicious URIs — links to potentially malicious external resources

Privacy First

Unlike online virus scanners that upload your file to cloud services, this tool runs entirely in your browser. Your PDF is never transmitted to any server — the analysis happens locally using JavaScript.

Frequently Asked Questions

QCan a PDF file contain a virus?

Yes. PDFs can contain embedded JavaScript, auto-launch actions, executable attachments, and exploit code that targets vulnerabilities in PDF readers. While modern readers have improved security, opening a malicious PDF can still pose risks.

QDoes this tool upload my PDF to a server?

No. The virus scan runs entirely in your browser using JavaScript. Your PDF file never leaves your device — there is no upload, no cloud processing, and no third-party access.

QWhat does the scanner check for?

The scanner analyzes the PDF's internal structure for JavaScript code, OpenAction/AA auto-triggers, embedded executables, known exploit patterns, and suspicious URI links. It provides a detailed report of each finding.

QIs this a replacement for antivirus software?

No. This tool performs static analysis of PDF structure — it catches common PDF-specific threats but cannot replace a full antivirus solution. For maximum protection, use this alongside your regular antivirus software.
