Inspect PDF in your browser
Look inside a PDF before you edit, archive, or troubleshoot it. The inspector reads the file in your browser and tells you its PDF version, number of pages, number of internal objects, and whether it’s encrypted. You can download the results as a JSON report.
- See the PDF version, page count, object count, and encryption status.
- Download a JSON report for your records or QA checks.
- Read-only, so your file is never changed.
- Find out in a moment whether a file is encrypted or readable.
How to use Inspect PDF
- Choose a PDF.
- Click Inspect document.
- Review the results and click Download report to save the JSON.
Technical notes & limits
- Reports pages, objects, version, and encryption. It doesn’t check content safety or fix damaged files.
- Up to 100 MiB per file, with a 120-second processing limit.
Know what you’re dealing with
When a PDF acts up or gets rejected by an upload form, it helps to know its version (like 1.4 or 1.7), how many objects it contains, and whether it’s encrypted. That tells you whether to compress, unlock, or repair it. The check runs in a sandboxed engine written in Rust and compiled to WebAssembly.
Not a virus scanner
Inspect PDF describes how a file is built. It isn’t an antivirus tool or a formal standards validator, so a clean report doesn’t mean a file from a stranger is safe to trust.
Frequently asked questions
Does Inspect PDF modify my document in any way?
No. It only reads the file to build the report. Your PDF isn’t changed.
What is included in the downloaded inspection report?
The PDF version, page count, total number of internal objects, and encryption status.
Does a successful inspection mean a PDF from an unknown sender is safe?
No. Inspection looks at how the file is built, not whether its content or links can be trusted.
