Before working with a PDF, it helps to know what you're dealing with. Folium's PDF Info tool reveals everything about your file — page count, file size, title, author, subject, creator application, and page dimensions — all read locally in your browser without uploading your document anywhere.
Reads title, author, subject, creator, page count, file size, and first-page dimensions.
Metadata is extracted and displayed in under a second for any PDF size.
Your PDF is inspected locally. No file is ever uploaded to any server.
Results are shown in a structured table for easy reading and comparison.
Drop your PDF or click Choose File. Any PDF version is supported.
After clicking Inspect PDF, pdf-lib reads all metadata fields from the document structure.
File name, size, page count, title, author, subject, creator, and page dimensions are displayed in a clear table.

PDF metadata inspection is entirely local. pdf-lib reads the document's internal metadata dictionary from local memory and displays the results in your browser. No file data is transmitted. No metadata is stored or logged by Folium.
