When text extraction fails, the cause is almost always one of three issues: image-only pages, encryption, or corrupt fonts. Use PDF to Text after fixing the underlying problem.
How PDF text extraction works
PDFs store text as drawing instructions (glyphs positioned on a page). Extraction decodes those glyphs into Unicode. Scanned PDFs skip this — pages are images until OCR adds a hidden text layer. Password-protected files block reading until unlocked.
Common use cases

- Legal review — feed clauses into diff or LLM tools
- Data cleanup — move text into Python or Excel scripts
Quick workflow
- Open PDF to Text.
