Optimizing graphic and content files for B.C. government web pages.
Graphics with large file sizes reduce performance and make pages slow loading. Larger graphics files also take up more disk space, which slows performance and increases costs.
Before inserting graphics into CMS Lite pages, make sure that:
- The correct graphic file type has been used for the type of image being displayed
- Files have been saved for web, and not saved for printing, in a graphics program
- Graphics have correct dimensions for their placement
- The file size for each graphic is under 250KB
Graphics Interchange Format (GIF)
Use GIF for graphics or logos with solid colour areas or background transparencies, but not for photographs.
Joint Photographic Experts Group (JPG)
Use JPG for digital photographs or images that don't have transparency.
Portable Network Graphics (PNG)
Use PNG for digital images that have a transparent area, for example, a logo or photo with a transparent or gradient background.
Scalable Vector Graphics (SVG)
Use SVG for images that may change over time, or need to scale without losing quality, such as logos and graphs.
Unless there is a legal, legislative, graphic design or print requirement, textual content should only be published in CMS Lite pages and not uploaded as files.
