Introducing Useful PDF Software

It is known to all that PDF is adopted by enterprises, educators, and governments around the world to streamline document exchanges, increase productivity, and reduce reliance on paper. And here I am going to introduce you several useful PDF software, hoping they will help you in your life and business career
DoPDF is a freeware Portable Document Format (PDF) printer developed by Softland, that allows any program that can print to create a PDF file. The resolution of the created PDF files can be set manually, or done automatically.
Features:
1. It supports 32-bit and 64-bit Windows 7, Vista, XP, and Windows Server 2000, 2003 and 2008 operating systems.
2. Allows custom resolution settings from 72 to 2400 dpi and predefined and custom page sizes.
3. PDFs created from text remain searchable in any of the 20 languages supported.
4. Does not use GhostScript or .NET and therefore is self-contained.
5. Very small download file size, which was 1.73 MB in doPDF version 6.3.311 and 2.98 MB in version 7.0.321.
6. Barely uses any memory or CPU resources when doing the actual conversion to PDF

Adobe Acrobat is a family of computer programs developed by Adobe Systems, designed to view, create, manipulate and manage files in Adobe's Portable Document Format (PDF).[1] Some software in the family, particularly the creating software, is commercial, and some is freeware. Adobe Reader (formerly Acrobat Reader) is available as a no-charge download from Adobe's web site, and allows the viewing and printing of PDF files.[2] Acrobat and Reader are widely used as a way to present information with a fixed layout similar to a paper publication.
Performance:
The application has been criticized for being slow to load and use. Workaround solutions have been developed to speed up the software. The application has been improved by Adobe, as version 7 of the software is indeed quicker to load; Adobe claims that Adobe Reader 7 users can "Open and save PDF files faster than ever" as version 7.0 launches "up to 50% faster than version 6.0".This works by installing a QuickStart program which runs every time the computer is turned on (and then quits). While it is often stated that this preloads the program into memory, using up memory resources, all it actually does is open and close each individual program file, allowing virus checking to take place in advance of the program actually loading. Note that this QuickStart program is for Adobe Reader/Acrobat 7.0+ only.

Foxit Reader is a multilingual PDF reader. The basic reader can be downloaded for free, while the full version is available for a fee.
And it is notable for its short load time and small file size, and has been compared favorably to Adobe Reader. It is not able to read PDX files (searchable catalogs), which limits its utility for use with document collections, and it does not handle the text ligatures correctly during text search and copy. It allows for annotating and saving unfinished PDF forms, converting to text, highlighting and drawing.
PDF Password Recovery 5.0 is an easy-to-use tool designed for removing passwords added to Adobe Acrobat PDF documents. It helps to decrypt protected Adobe Acrobat PDF files, which have "owner" password set, preventing the file from editing(changing), printing, selecting text and graphics(and copying them into the Clipboard), or adding/changing annotations and form fields. PDF decrypt is being done instantly. Decrypted file can be opened in any PDF viewer without any restrictions -- i.e. with edit/copy/print functions enabled. All versions of Adobe Acrobat are supported. It also recovers document open passwords.
