pdf-inspector
pdf-inspector: parser local, OCR o pipeline gestionado
Compara calidad, privacidad, latencia, coste y operaciones.
Qué aprenderás
- Trace detection and layout stages
- Run native extraction and OCR safely
- Design provenance checks
Antes de empezar
- Basic Git and command-line usage
- Comfort reading a project README
You can explain the project, run its documented first step, and decide what to verify before adopting it.
Conclusiones clave
- Document mix determines the best parser.
- Equal fixtures expose layout and OCR trade-offs.
- A stable output contract preserves exit options.
Match the document mix
Usa el mismo corpus de texto, scans, mixed, columnas, CJK, tablas y fuentes rotas y conserva un contrato de salida migrable.
Use the pinned source evidence, record versions and assumptions, and ask a qualified reviewer to validate the result before adopting it.
Run an equal fixture
Compare text, scanned, mixed, columns, CJK, forms, tables, and broken fonts using the same corpus. Score extraction quality, page provenance, latency, privacy, integration effort, and failure recovery.
Choose an exit path
Keep the original PDF and a normalized output contract so switching engines does not rewrite downstream systems. Document when to route to OCR or human correction.
Use the pinned source evidence, record versions and assumptions, and ask a qualified reviewer to validate the result before adopting it.
Cómo elegir
| Criterio | Opción A | Opción B |
|---|---|---|
| Best when | You need predictable behavior and easy auditing | You need adaptive optimization and have reliable telemetry |
| Main risk | May leave performance on the table | Can become difficult to explain or debug |
Pasos de implementación

Is pdf-inspector a full OCR replacement?
No. It provides selective local OCR integration; a hosted or specialized OCR path may still fit difficult documents.
When is a hosted pipeline preferable?
When managed OCR breadth and operations outweigh local control and data-residency requirements.
