Frequently Asked Questions

Is the OCR text extraction secure?
Yes. All recognition is computed locally inside your browser using Tesseract.js WebAssembly. No image data is ever dispatched to external servers.
What makes a PDF searchable?
A searchable PDF overlays a transparent text layer accurately matched directly over the scanned pixels, letting you search, highlight, and copy cleanly.
Can it extract multiple languages?
Absolutely. Select any of our supported language modules (e.g., English, Spanish, French, Japanese, Korean, Arabic) to download the correct trained data models.

From Picture-of-Text to Actual Text

What OCR can read — and what defeats it

OCR accuracy is decided before the software runs — by the scan itself:

Source materialExpected accuracyNotes
300 DPI flatbed scan, clean printExcellent (99%+)The gold standard
Phone photo, good light, flat pageGoodCrop to the page edges first
Faded photocopy or carbon copyPatchyBoost contrast before OCR if possible
HandwritingPoor to noneOCR engines target printed text
Urdu Nastaliq scriptWeakLatin-script engines misread it; expect manual correction

How a searchable PDF actually works

OCR doesn't replace your scan — it adds an invisible text layer positioned behind the page image. The document looks identical, but now Ctrl+F finds words, text can be selected and copied, and screen readers can speak it. That last part matters for accessibility compliance, and the search part matters the day you need one clause in a 200-page scanned agreement.

OCR's place in the pipeline

OCR comes first, always: run it before converting with PDF to Word (otherwise Word receives a picture), and before extracting tables with PDF to Excel. Compressing is fine afterwards — the PDF compressor preserves the text layer while shrinking the page images that make scanned files huge.
