Get a quick structural inventory of a PDF. This browser-based scan counts common object and resource markers directly in the file bytes.
Count indirect objects, streams, page markers, images, fonts, forms, annotations, and JavaScript markers in a PDF byte-level report.
Counts are diagnostic estimates; object streams and compressed cross-reference data can conceal nested objects from a byte scan.

No. Processing runs in this browser. The page does not send the selected file to a Callpdf server.
PDFs that require a password are not supported in this version. Remove protection with the correct password before using the tool.
Large documents may use substantial memory and can take longer. Close other heavy tabs and try a smaller file or fewer pages if the browser stops.
The report does not alter the PDF. Its measurements are a practical browser-based inspection and documented limitations still apply.
A current desktop version of Chrome, Edge, Firefox, or Safari is recommended. Browser memory limits vary by device.
