At present, Secco OCR is the best one to recognize formulas, which can recognize various PDFs. Both WORD and tables, especially mathematical or physical formulas, can be directly converted into WORD. Scanned pictures can also be converted into word. Pay attention to pictures whose resolution is set to 300DPI, grayscale or color.

I often write some math questions, and only Saiku can recognize formulas and convert them into word.

Powerful software with high recognition accuracy and the best conversion formula, I found it as a treasure, great, and solved my big problem.

It can be downloaded and recommended to friends in need.
