Free Online Tools For Converting Files

Media Convert
Media Convert is, for most users, the most powerful online file conversion system. Not only can it process dozens of document, images, movie, audio, video, archive and other file types, it also has an advanced set of options that let you do things like add ID3 tags to images, trim videos and resize images on the fly. It can take file sizes up to 200 MB, more than most of its competitors. Though the interface can be a bit confusing, especially in case where the automatic file detect doesn’t work, it makes up for it somewhat by being able to send files via email or to your mobile device. A file hosting option is also available.

YouConvertIt
YouConvertIt has a slick Web 2.0-style interface with lots of JavaScript to make the process of uploading files extremely quick and it supports most document, audio, video, image and archive file types. YouConvertIt has a relatively small file size limit of 80 MB, which goes up to 100 MB for those who are registered, but offers larger file sizes for those who are just sending files through the service and not doing any conversions.

FreeFileConverter
Free File Converter has a robust 300 MB maximum for file conversions (the largest in this list for free) and offers a fairly standard selection of file types including documents, images, audio, video and archives. The interface is very simple, similar to Zamzar, and the site loads reasonably quickly most of the time.

Convert.Files
On the surface, Convert.Files is a fairly standard file conversion system, offering 150 MB file sizes and a standard array of file types, including documents, images, audio, video archives. However, not only does Convert.Files support a wide array of drawing and CAD files, but it also has the ability to read text within certain images, letting it convert images and image-only PDFs into clear text for editing.

Online Converter
The interface to Online Converter is different than others, starting with the file you wish to export to rather than the one you’re starting with. It offers a solid array of audio, video, image, document and ebook files and also offers a hashing system for determining the authenticity of downloaded files. Also has advanced features for each category of file that lets you trim/normalize audio, resize/colorize images and change video bitrate. File size is limited to 100 MB per file and can also convert video directly to Xbox and Wii format for easier viewing on those platforms.
