What you get
- OCRmyPDF returns a PDF with a searchable text layer and supports explicit PDF/A output.
Choosing this tool
OCRmyPDF fits existing scanned-PDF archives that need a searchable layer and repeatable command-line handling. NAPS2 is more convenient for scanner capture and page arrangement; Umi-OCR offers a desktop batch interface. This is recognition and document processing, not a promise to reconstruct tables as spreadsheets.
A decision worked through
A 500-page bilingual archive has no 500-page software bill. Run a ten-page sample with the correct combined language codes first, then inspect copied text and page appearance. If the language pack is missing, increasing the machine size does not fix the recognition configuration.

- Validate the search layer and preserve originals before batch automation.
Requirements & installation
- Install OCRmyPDF with Tesseract, Ghostscript and language packs through a documented platform package or container.
Limits & review
- OCR can misread low-quality scans, unusual layouts and unsupported languages. Searchable text is not verified data extraction; review destructive processing choices and retain originals.
Your part
- Compare copied text, page order and visual appearance with the original before replacing an archive file.
