Pros & Cons from Real Users Pros Very comprehensive set of APIs that allow the developer to create complex applications. The support has also been excellent. A very high quality SDK for all things PDF. As I understand it, it's based on the same code that Adobe products (e.g. Acrobat) use for PDFs, with some additions. That makes it essentially the reference SDK for PDF. The included support can be very helpful. Can be used with C#, Java, and C++. - It has one of the largest collections of PDFs. - There is a lot of variety for all the genres. - It has an easy and simple UI. Adobe PDF library is a nice and fancy tool. It has a lot of options and choices to choose from. Recommended. It makes it easy for managing documents. It offers files type conversion with a PDF reader. Very easy to use. Easy to create, edit documents and read large PDF files. Cons Because there are so many APIs, it takes a while to fully understand them and how they are used together. It's for-pay closed-source software. Has a bit of a learning curve to get started, at least when used with C++. Probably not a good match for very small projects. - The price of the software and PDFs is quite expensive. I liked the platform so far. I don't have any cons as such. It worked great for me. Nothing to share about cons.	Pros & Cons from Real Users Pros Absolutely love that SmallPDF is available through a web browser, meaning we do not need to download and install any software and that it is accessible anywhere we are regardless of which computer we are using. It has most the features we use for editing PDFs including inserting text and converting PDF files to Word, and it integrates nicely with Google Suite. The overall design and UX is also very slick and intuitive. The convenience of being able to convert to and from PDFs, along with a range of file manipulation options whenever I want, makes Smallpdf a no-brainer compared to the the huge expense and bloated nature of the market leader. It does exactly what I need it to do, 95% of the time, the balance is usually page "overflow" and not hard to rectify. How easy it is to use, and the price. Also, the style is beautiful. And you can compress the document right after editing and signing it. Cons Coming from someone who also uses Nitro Pro, SmallPDF is missing the feature to directly edit existing text and images on a PDF file while retaining original formatting. This means I have to occasionally revert back to Nitro Pro if I need to edit existing text and images on PDF files (as opposed to adding text or images to PDF files, which is what SmallPDF can do). The service could do with a custom option - there are tools I use all the time but there is no option to have shortcuts to these particular tools on the main menu. As a subscriber it would make sense to have that option rather than having to go through the whole list of tools to select the same thing each time. Conversion from pdf to jpg is not high resolution so the images do not stand up well on a web site. The Word to PDF conversion does not like "tight" pages and will overflow a two-page Word file into 3 pages of PDF, which can be frustrating but if you are aware of the problem then you can adjust the volume of copy accordingly to compensate. I would like to have more featured with editing my documents.
