PDNob explains causes and solutions for extracting text from PDF images

Users often encounter difficulties extracting text from PDFs when the content is saved as an image rather than text data. This typically occurs with scanned documents or photos of physical papers. Other common obstacles include security settings that restrict copying and low image quality, such as blurriness or shadows, which can hinder recognition accuracy.

To resolve these issues, Optical Character Recognition (OCR) technology can be used to convert images into editable text. Recommended methods include using dedicated PDF editing software like PDNob, which allows for language settings and text conversion, or utilizing Google Drive by opening PDFs with Google Docs. Additionally, online OCR tools and converting PDFs into image formats are viable alternatives, though users should remain cautious regarding privacy and data handling when using online services.
