PDF Format

PDF (short for Portable Document Format) images are a good choice for saving simple vector graphics to use in desktop applications. They have a ".pdf" extension.

PDF images are great for simple 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.

Note: There are some features of Opacity that the PDF format does not fully support, like filters and transparency in gradients. If you save a PDF image that has such issues, Opacity will give you a warning letting you know. You will also get a warning if you save a PDF image with pixels in it, as this type of content will not automatically scale to different resolutions.
