You can use this Save For Web feature in Photoshop to optimize your images.
When you're ready to save an optimized
version of your image
go to File-->Save for Web
You can use 2-up or 4-up to compare different compression settings. Here we have:
| Original Image: | 198k |
| Low JPEG (quality 5) | 6.673k |
| GIF (256 colors) | 40.08k |
| Medium JPEG (quality 50) | 17.98k |
|
Select one of these 4 previews
and it will have a black box around it. The settings on the right correspond
to the image that is selected. |
|
In this case, the lowest
file size is the 6.673k JPEG image, but it is too blurry to use. |
|
Notice that the GIF image's
file size is twice as big as the JPEG image next to it (bottom right) |
|
In this situation, the best
choice is the 17.98k JPEG. It is the lowest file size of an acceptable
quality image. |
| Never have an image over 30k! |
| Always save a copy of the
original, in case you need to edit your image, or later decide to compress
it differently. |
