PDF Link Extractor

Here's a gap the big PDF sites never closed: Smallpdf, iLovePDF and Sejda will compress, merge and convert your PDFs all day, but none of them will hand you a list of the links inside one. That leaves researchers, marketers and anyone auditing a document doing the miserable version — opening the PDF, hovering over each link, copying URLs one at a time. A 200-page industry report can hide hundreds of source links; harvesting them manually is a full afternoon.

The trickier half of the problem is invisible links. A PDF doesn't have to show you a URL for it to exist — a "read the full study here" sentence can carry a real hyperlink destination in the file's annotation layer. Those are exactly the links a text-only scan would miss. This tool reads both layers: the annotation destinations (labeled "hyperlink" in the results) and every URL-shaped string in the page text, then merges them into one clean, deduplicated list.

A few honest caveats worth knowing. Duplicate-looking URLs that differ only by capitalization or a trailing slash are treated as one link — that's intentional, since they go to the same place. Very long URLs that wrap across lines in the text layer are reconstructed as best as possible, but a PDF that hard-wraps a URL mid-word can occasionally produce a shortened match; spot-check anything critical. And scanned-image PDFs have no text layer at all, so there's simply nothing to extract — the tool will tell you zero links were found rather than invent any.
