The following review written by one of the Software Informer contributors applies to version 3.1
Aiseesoft PDF Converter Ultimate is a program that converts PDF documents into Images, Word files or HTML formats.
The application has an uncluttered interface and an attractive design.
The home page displays a quick guide about how to use the tool. Once you add a file, you can see some details about its size, the number of pages, the pages that you have selected to convert and the output's name and format.
If you want to convert files into images, you can choose from the following formats: JPEG, PNG, GIF, BMP, TGA, PPM, or TIFF. You can also convert your files into some text formats. The available ones are Microsoft Word 97-2003, Microsoft Word 2007, Rich Text Format, Microsoft Excel 97-2003, Microsoft Excel 2007, Microsoft PowerPoint 2007. The last two formats that you can select are EPUB and HTML.
The trial version allows you to convert only the first 3 pages of a PDF document, but there is no limitation if you use the full edition. The same way it works with watermarks. I mean that a watermark is added to the image formats until you buy the product.
The program provides an interesting option which offers you the possibility to select only the pages that you want to convert in case you aren't going to process the whole file. There is a function that allows you to change the output settings for every single format. For example, if you want to convert a PDF document into an image, you can change the resolution, the pixels or the color. If you choose to convert into a text document, you have the possibility to change the text's encoding or to select whether it should maintain the layout or not.
Another important feature of this tool is its optical character recognition function. The accuracy mode offers you the best quality for this process, while the speed mode provides an ability to recognize characters in the fastest way.
In conclusion, this application works fine providing its users with a fast and efficient conversions. The developers wanted to make a program that everybody could use without any difficulty and they succeeded. The only thing that has been left out, in my opinion, is an option to select other skins. Some more templates would definitely give this app an outstanding look.
