GIF and JPG - Which is for what?
by Robyn Harton
GIF and JPEG are two of the most used file formats on the
Internet today. GIF stands for Graphics Information Format;
JPEG (abbreviated JPG) stands for Joint Photgraphic Experts
Group format. They are both excellent formats, however, it
helps to understand the good points and limitations of each.
Below are the same images, saved in each file format from
Photoshop originals, to compare the differences in file type
usage.
GIF |
JPG |
| Photographic
Image Comparison |
| 
file size ~5kb
Poor "dotty" (pixelated) look at same file
size.
|
file size ~5kb
Significantly better picture quality at same file size.
|
| Other Image
Comparison |
| 
file size ~2kb
Smaller file size with greater clarity
on edges of images in the graphic.
|
file size ~4kb
Fuzzy, odd colored edges in the graphic
even at a larger file size.
|
In summary, GIF is usually a better choice for images with
large areas of color and few gradients. JPG is usually a better
choice for photographic images or images with gradients.
