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.
