Pros & Cons from Real Users Pros The operation is convenient, the interface is simple, and it has all the basic functions, more importantly is that there are no advertisements. Nothing. I got the permanent license version and it turned out to be nothing but vapor ware. I've spent hours going round in circle and I still can't edit font size. Cons OCR function sometimes does not work, hope it can be optimized in the future. Can't edit font...Can't find edit menu. Paid $89 for subscription and got no more functionality than I had with free version.	Pros & Cons from Real Users Pros Can't think of a better tool for this simple purpose of merging. There's an equally useful looking splitter function that I haven't used for a long time. PDFsam is okay to edit files as long as standards compliance is not a priority. The edit features work fine. It's like any other PDF software on the market. You need to pay a premium for electronic signatures and editing of all things. -Very intuitive interface -It's very quick and easy to split or merge PDFs -No ads on the free version, they don't push for premium Free and open source. Merge PDF files together. Split PDF file or extract pages. Multi platform availability. Cons Worried it'll convert itself into a subscription based app. It is impossible to print properly. As an example, duplex printing just does not work, and PDFsam manages to mess this somehow by taking control of the print driver even if the printer is hard-set to duplex printing. The only working solution I found is to use a different program to print the pdf after editing it with PDFsam. Buying a license is an absolute nightmare. They claim the license is $19.99 lifetime and as soon as you pay it turns into a subscription of $100 a year, no refunds. They start to add additional services randomly, and charge you, No customer service, I had to get my bank to put a stop payment, I had selected a basic plan and they had tacked on additional plans without my approval. There are honestly no cons for me, PDFSam does what it must. It would be great if the converter tool would also be free, but I understand they have to make money somehow with premium. No editing or conversion feature - available in PDFsam enhanced which is paid.
