SVG Format

SVG (short for Scalable Vector Graphics) images are a good choice for saving vector graphics to use in web pages. They have a ".svg" extension, or a ".svgz" extension when compressed.

SVG images are great for vector graphics because instead of storing a set of bitmaps they directly store vector information. This means that they can be scaled to any resolution and still look crisp. They are increasingly supported by web browsers, but support for SVG images is not yet universal. If backwards compatibility for web graphics is important for your project, you should also consider the PNG, GIF and JPEG formats.

Note: There are some features of Opacity that the SVG format does not fully support, like filters and pixels. If you save a SVG image that has such issues, Opacity will give you a warning letting you know.
