A great choice is the free PDFill PDF Tools covering most basic functions.
|Clean and nice user interface, include most features such as merge, split, reorder, rotate, header and footer with page number, watermark, encrypt and decrypt, convert PDF to images or vice versa, convert PostScript to PDF.|
|Short of features provided by Specific Tools.|
PDFill PDF Tools is my favorite with its nice, clean user interface covering most functions, including merge pdf files, split or reorder pages, rotate or crop pdf pages, add headers and footers complete with page numbers, etc.
Watermarks can be added either by typing in some text (such as ‘DRAFT’ for documents to be reviewed), or by inserting a background image in PDF format.
Some additional features are supported, such as encrypt and decrypt with security options; reformat multiple pages into one page; delete, flatten or list PDF form fields; convert PDF to images or vice versa; and convert a PostScript file to PDF.
Note that PDFill PDF Tools can be run from within PDFill PDF Editor, which is not free, but a separate installer containing the Tools only is also provided by the developer.
The PDFill PDF Tools requires GhostScript to be installed before use. It does not support functions such as converting PDF to text, making annotations, etc. Those features are available in other pdf tools.
