Is my PDF uploaded anywhere?

No — the file is read and inspected entirely in your browser using JavaScript's File API. It's never sent to a server, which matters for confidential or unpublished documents.

Why does it say the results might be incomplete for some PDFs?

Newer PDFs can bundle multiple objects — including page definitions — into a single compressed "object stream" for a smaller file size. This tool reads a PDF's plain-text structure directly rather than running a full PDF decoder, so it flags this case explicitly instead of guessing at a number it can't fully verify.

Why do some pages share one size instead of being listed individually?

PDF allows a page size to be set once on a shared parent node and inherited by every page under it, rather than repeated on each page — very common for documents where every page is the same size, like a standard Letter or A4 report.
