Online converters always come in handy. Once you need to perform some operation with your files, they can save your time achieving the same results online, without installing some specific software. In fact, there are many online tools, which convert formats, files and code snippets for free. Some of them are quite specific tools aimed for developers, but some are common “all-rounders”, which manage to convert almost every format to a more popular one. Using them, you can generate .pdf-documents out of images, images out of texts or RSS-feeds out of web-sites. You can also convert any audio- and video-files immediately – the results can be received via e-mail.

So what can you use? What should you use?
