Pros & Cons from Real Users Pros Folks at adobe should learn coding from these guys. I gave up on Adobe Reader as: 1. Its scrolling speed was less than satisfactory at zoom level other than 100%, for long pdf files, for graphic heavy pdf files with images and/or mathematical notations. 2. It would always reduce document window space in by incorporating various toolbars to the right/bottom at opening time. 3. It would also not remember last opened page view by default. 4. Shameless popups of adobe paid services and digital signature warnings. Sumatra PDF does not have any of these problems. Free and open source. Minimal User Interface - Easy to use. Supports pdf, epub, mobi and other formats. Low memory usage and quick to load files. Portable software. Cons Advanced settings opens a notepad file, containing sensitive settings, that, if edited incorrectly, may break the program. Would be better to make it a GUI based menu. Doesn't support editing. The design is outdated (No annotations as well).	Pros & Cons from Real Users Pros User friendly software; the icons are tiny and not labeled but the labels pop up when mouse pointer is moved over the icon; good options to export to other formats; I like the OCR recognition feature which works fine; software works as expected; no bugs; good pricing. I think there are three pros to this tool. 1. This is the first real free PDF editor I've ever used. It is 100% free to edit text and images in PDF documents. 2. The interface is very beautiful and eye-catching which is quite different from other PDF tools. 3. The performance is good. Cons Very tiny icons which are not labeled; cannot cut-and-paste selected areas of a page; no phone customer support; had to send 5 emails before they responded; promised me one year use of UPDF AI but I never got to use it since they only gave me 2 weeks with a warning that they would automatically charge my credit card; scary customer support since they have no phone number of address in the U.S. Only in China. It is rather new in the market. At first, I don't trust it as I have never heard of it. But once I tried it, I begin to love it.
