Description
📝 Description
This workflow allows you to extract all links (URLs) contained in a PDF file by converting it to HTML via PDF.co and then extracting the URLs present in the resulting HTML.
Unlike the traditional Read PDF node, which only returns visible link text, this flow provides the full active URLs, making further processing and analysis easier.
📌 Use Cases
- Extract all hyperlinks from PDF documents.
- Automate URL verification and monitoring within documents.
- Extract links from reports, contracts, catalogs, newsletters, or manuals.
- Prepare URLs for validation, classification, or storage.
🔗 Workflow Overview
- User uploads a PDF file via a web form.
- The PDF is uploaded to PDF.co.
- The PDF is converted to HTML (preserving links).
- The converted HTML is downloaded.
- URLs are extracted from the HTML using a custom code node.
