About this tool
A closer look at File Information
File Information inspects a PDF and shows page count, file size, page dimensions, PDF version and page render data — without uploading the file. The results can also be downloaded as a JSON file.
It is the quick sanity check before further processing: confirming how many pages a PDF has, checking the version, or reviewing basic document details before sharing.
Dimensions shown are for the first page, and some fields are best-effort browser inspection results. The inspection runs entirely in your browser.

Troubleshooting
The version shows 'Unknown'
Inspection reads the PDF header from the first bytes; some unusual or repaired files carry a non-standard header.
I need per-page details
This tool summarizes the first page and the document as a whole — use Organize or Split's thumbnail preview if you need per-page inspection.
