OCR PDF vs. PDF to Text
Reading text out of a scanned image vs. extracting text that's already there.
PDF Tools
PDF to Text extracts a PDF's existing text layer directly — fast, since the text is already stored as text in the file. OCR PDF is for when there's no text layer to extract, because the PDF is actually a scanned image: it renders each page and uses optical character recognition (Tesseract) to recognize characters from the picture, which is real image-recognition work and noticeably slower.
PDF to Text
Best for
- PDFs created digitally (exported from Word, a web page, etc.) that already have selectable text
- Fast extraction when you just need the words
Trade-offs
- Produces nothing useful on a scanned/image-only PDF — there's no text layer for it to read
OCR PDF
Best for
- Scanned documents or image-only PDFs with no real text layer
- Recovering text from a physical document that was photographed or scanned
Trade-offs
- Meaningfully slower — each page is rendered as an image and recognized character-by-character
- OCR accuracy depends on scan quality, font, and language selection
| Dimension | PDF to Text | OCR PDF |
|---|---|---|
| Works on | PDFs with an existing text layer | Scanned/image-only PDFs |
| Method | Direct text extraction | Optical character recognition (Tesseract) |
| Speed | Fast | Slower — recognizes each page as an image |
Verdict
Try PDF to Text first — if it returns real text, you're done. Only reach for OCR PDF when PDF to Text comes back empty, which means the file is a scanned image with no text layer to extract.
