I made a site recently that works pretty well for this for a lot of sample scanned PDFs I tried, you might get good results: https://fixmydocuments.com/ https://fixmydocuments.com/ I also made a simple iOS app that basically just uses the built in OCR functionality on iPhones and automatically applies it to all the pages of a PDF. It won’t preserve formatting, but it’s quite accurate in terms of OCR: https://apps.apple.com/us/app/super-pdf-ocr/id6479674248 https://apps.apple.com/us/app/super-pdf-ocr/id6479674248
