Inkscape is an open source vector graphics editor, with capabilities similar to Illustrator, Freehand, CorelDraw or Xara X, using the W3C standard: the Scalable Vector Graphics (SVG) file format.
The program has multiple options such as the possibility of handling image formats such as PNG, JPG, BMP or TIFF; layer systems; predetermined figures; etc.
This application is also capable of editing in XML, as well as having almost all the tools of any vector image editor.
Inkscape’s main goal is to create a powerful and comfortable drawing tool, fully compliant with XML, SVG, and CSS standards.
When designing logos or having the need to use certain images in web projects, the use of vectorized images instead of bitmaps is very useful due to the obvious limitations of the latter format when it comes to enlarging them without losing resolution. Of course, it is not necessary to resort to commercial suites such as Adobe Illustrator or Corel Draw for this purpose, since there are free alternatives such as Inkscape. This tutorial explains the basics of vectorizing an image.
