Drop any PDF to instantly see its page count, file size, every distinct page size inside, and the embedded document title.
Your PDF is parsed locally with pdf-lib and never leaves your device.
Drop a PDF here or click to browse — one file at a time
Dropping a PDF hands the file's bytes to the open-source pdf-lib library, which parses the document structure right here in your browser. The page count, page dimensions and the embedded title are then read straight from the parsed object — no rendering engine, no server.
No — this tool takes one PDF at a time, but it is fast: load a file, read the result, then click the drop area again for the next document. Batch tools that tally many files at once exist, but they usually mean uploading a folder somewhere, which this site deliberately avoids.
Only intact ones. The page count comes from the PDF's page tree, so the file has to parse correctly. A truncated download or a corrupted cross-reference table produces a clear error message instead of a guessed number. Password-protected PDFs are detected and reported honestly rather than bypassed.
Common with scanned or merged documents: every page carries its own dimensions, so one file can mix A4 pages, US Letter pages and an odd-size insert. The unique-sizes list shows exactly what is inside — useful before duplex printing or sending a file to a service that expects a single paper size.
A few seconds at most for typical documents. The whole file is read into memory, but only its structure is inspected — nothing is laid out or rendered — so even a few-hundred-page text PDF is effectively instant. Very large scans depend on your device's memory, not on any server.
No. The page tree is read with pdf-lib inside your browser tab. There is no upload step, no account, and no network request that contains your file.
If you just finished with PDF Page Count, the natural next steps are PDF Page Numbers, Sign a PDF, PDF Metadata Editor, or browse every tool in Privacy File Tools.
