IV. Summary

The above introduces the method of converting scanned PDFs to TXT files. Among several PDF software with OCR technology, Renee PDF Aide and Google Docs have simple interfaces suitable for novices. However, Renee PDF Aide offers OCR language packs in English, French, German, Arabic, Spanish, Portuguese, Chinese, Korean, Japanese, and more. Selecting the appropriate language pack for the PDF text results in higher conversion accuracy compared to Google Docs.
The Soda PDF software provides many PDF-related operating tools, so its interface is more complicated and the operating threshold is higher, which is suitable for professional users who have more operating requirements for PDF files.
