Why people extract links from PDFs

PDFs collect links over their lifetime — citations, tracking pixels, dead URLs from a 2017 deck. Auditing what's actually in there is its own job.

Link-rot audits

PDFs published 5 years ago link to URLs that no longer resolve. Pull every link, run a HEAD-status check, replace dead ones before reposting.

Privacy / tracking review

Some PDFs carry tracking pixels disguised as link annotations. Knowing every external URL surfaces what your file phones home to.

Content migration

Moving a PDF library to a CMS or static site. Links need to be re-anchored to the new URL structure — first you need the full list.

Citation verification

Academic and legal documents reference URLs. Auditing the link list confirms every citation actually points where claimed.

Internal-doc QA

Internal PDF guides often link to outdated wiki pages or moved Confluence URLs. Audit before redistributing to avoid sending readers to 404s.

How Extract Links works

Three steps, no signup, no uploads.

STEP 1
Drop your PDF
Up to 100 MB. Byte parser walks every page's /Annots array in your browser.
STEP 2
Click Extract links
We surface every /Subtype /Link annotation, classify external (URI) vs internal (Dest), record the page each appears on.
STEP 3
Copy or export
Copy as JSON for pipelines, or download as CSV for spreadsheets and link-checkers.

What makes pdfcraft ai different

Same engine Chrome uses
PDFium is Google's PDF engine — the one that powers Chrome's built-in PDF viewer. We compile it to WebAssembly so it runs in your browser at near-native speed.
100% local processing
Most free PDF tools upload your file to a server, process it, and stream the result back. We don't. Your file lives in your browser tab and never touches our infrastructure. Verifiable in your browser's Network panel.
No watermark, no signup, no daily limit
Convert 1 PDF or 1,000. We don't gate on volume because there's nothing to gate on — the engine runs on your machine.
Honest about limitations
When something the tool can't do (encrypted PDFs, cross-reference streams), we tell you clearly instead of failing silently. Same for partial results: sampled vs exact, embedded vs not.
Open standards, free engines
PDFium is BSD/Apache licensed (free for any use). We don't pay vendor license fees and pass that savings on to you (and to ourselves) as a free, ad-supported tool with no upgrade-to-pro pressure.

Frequently asked questions

Does it find links that are just text in the PDF, not clickable?

No. We only find link annotations — the clickable rectangles. Plain-text URLs that happen to look like links but aren't anchored as link annotations don't count. For those, use Search in PDF and search for 'http' or your domain.

Does it check whether the links are alive or dead?

Not yet. We list URLs; checking which ones still resolve requires HTTP requests we don't make in-browser (CORS would block most of them anyway). Run a desktop link-checker like linkchecker or htmlproofer on the exported CSV.

Internal links — what do those look like?

Internal links jump within the PDF, e.g. 'Page 3 of contents' linking to page 47. We surface them as 'Page object N' or 'Named: <name>' depending on which destination form the PDF uses.

What's the difference vs PDF Annotations Export?

Different annotation types. /Link is its own /Subtype — that's what this tool surfaces. Other annotations (highlights, comments, sticky notes, drawings) go to PDF Annotations Export. The two tools are complementary scans of the same /Annots array.

Is anything uploaded?

No. Pure byte-stream parsing in your browser.

Want comments + highlights too?

PDF Annotations Export pulls every comment, highlight, and sticky note — same single byte-stream pass.
