PDF Inspector
Open-source PDF structure visualisation — inspect text blocks, images, and metadata inside any PDF, essential for debugging document parsing
github.comPDF Inspector is a companion tool to AnyDoc from Firecrawl. It lets you visually inspect the internal structure of any PDF — text blocks, images, fonts, metadata, and the document’s internal object tree. For anyone building a document processing pipeline (extracting tables from government reports, parsing scanned forms, preparing documents for LLM ingestion), PDF Inspector reveals why a particular PDF is parsing incorrectly: is the text actually embedded or is it an image? Are the tables using real table structures or just positioned text? Is the font encoding garbled? The tool runs in the browser — just drag and drop a PDF — and requires no setup.
