A scanned PDF looks like a document, but to a computer it is often only an image of a page. OCR tries to recognize text from the image and save it as editable DOCX.
What improves the result
Best results come from sharp scans, straight pages, enough contrast, and correctly selected languages. For Slovak documents, Slovak plus Czech or English can help depending on content.
If the document is blurred, low resolution, or uses decorative fonts, OCR can fail or produce wrong characters.
When to use OCR and when to use the PDF editor
If the PDF has a text layer, the PDF editor is often enough. If text cannot be selected and the page is just an image, use OCR first.
After OCR, review the DOCX, fix diacritics, numbers, amounts, and names. For accounting data, never rely only on automatic recognition.
Security and privacy
An OCR tool should clearly say whether processing happens in the browser or on the server, what file-size limits apply, and how long temporary files remain.
For sensitive documents, delete temporary exports after completion and keep only the final working output.
