OCR scanning feature needs improvement.	Pros & Cons from Real Users Pros The team at PDFrest is incredibly helpful — they respond quickly, clearly, and even took individual feature requests into account without delay. The API itself is fast, user-friendly, and well-documented. A solid, reliable partner to work with. pdfRest is surely a business oriented PDF converter because it can convert all sorts of files, small and large, landscape or portrait, into splendid and crisp PDFs for all purposes. It is the best documentation tool in the market for creating, editing and converting office suite documents into PDF. Really liked its simple to use procedures.

Cons The team at PDFrest is incredibly helpful — they respond quickly, clearly, and even took individual feature requests into account without delay. The API itself is fast, user-friendly, and well-documented. A solid, reliable partner to work with. Multiple file upload options is missing or I didn't find the option, either ways would appreciate some guidance. I do not have complaints at the moment with regards to execution of the tool or its processes. OCR feature could have been a lovely add. I hope the makers add this feature soon. One area where the platform falls short is in its limited language support. PDFRest currently only supports English, which can be a significant limitation for users.
