Last Friday I found quite nice service for vectorization of raster images. The service is provided from University of Stanford.

The front end is written in flash or flex and the interface is very intuitive and easy to be used. There are input image detection, quality levels and also ability to edit the preview of the image.

The supported input formats are JPG, GIF, PNG, BMP, TIFF and EPS, SVG, PNG are the output formats.
The comparison results showing that this tool is better than Adobe and Corel alternatives.

It’s very nice tool I really enjoyed with it /while I tried to vectoring my own portrait :)/
This service seems to be already very popular – according to their blog there are already 1,000,000 uploads.

Hope you like it too.

Update: The service becomes paid. Although you have 2 free credits while you sign up.
