Doc Convertor is an excellent tool, especially designed for programmers. It lets you convert your source code to more that 10 different formats of various types.
Doc Convertor automatically recognizes all types of source code (whether HTML, CSS, ASP, PHP, C, C++, C#, VB6, Perl, SQL, Pascal, etc). Once the source code is detected and recognized, you can export it directly to any of these formats: PDF, BMP, JPG, PNG, SVG, Excel, Lotus, Quattro Pro or even HTML.
Doc Convertor lets you convert various files simultaneously, and it also has different printing options.
Curiously it is available in various languages (including Catalan) but not Spanish.
