Choosing Image Format for Web
Written by Samuro on Wednesday, October 31st, 2007 in Web Design.
Choosing right images format (image optimization) is one of ways to make your sites/blogs loading more faster. There’s three image format that usually used, jpg/jpeg, gif and png.
Each type of image format have the insuffiency and excess. So, as webmaster had to know the insuffiency and excess of each image format, then can choose the right format for different situation.
For example; image size 125×125 pixel, one color (black). Then save it as jpg, file size can be 11332 bytes though it save with the low quality. But if it saved as gif format, file size is just 192 bytes (gif 64 dithered).
Comparison of image quality:
- GIF. Small size if the image have little color. For image which have a lot of color like photo, use the JPG format. You can do experiment which the effective and optimized format.
- GIF format own the clear and bold color, jpg format sometimes become blur if saved at low quality.
- For transparent image, better use gif or png format.
You can try by saving same image with different image format. I usually saving gif format with quality 64 dithered, saving jpg format with medium quality.
