Searchable PDF
Converting to searchable PDF is a miss. It does this thing where it looks the text is was printed twice. Not sure. In addition, it takes a long while for it to convert a PDF file. A 20 page PDF took me about 5-10minutes to finish converting. Im using an iPad Pro 9.7. If your looking for an app that converts pad files to scannable PDF. Try Scanbot. The app converts at half the speed quicker with no inconsistencies.
