doPDF is a Office Tools software developed by Softland. After our trial and test, the software is proved to be official, secure and free. Here is the official description for doPDF:
Brothersoft Editor: Customizable resolution - you can choose any resolution from 72 to 2400 dpi. Predefined/custom PaGE sizes - choose a Default page size (Letter, Legal, A4, A5, A6, ...) or enter your own custom page size. Searchable PDFs - you can search for text within the created PDF file (and search engines will also index the text from the PDF). Multi-language - choose a language for the user interface from the 20 languages Currently supported (credits). Do your part in saving the planet - instead of consuming paper to print your document, why not create a PDF file out of it and spare a couple of planet-saving trees? Barely uses any computer resources - compared to other free PDF converters, doPDF barely uses any memory or CPU resources when doing the actual conversion to PDF.
