4kb – thats quite a bit for web images. Here is a quick tip to reduce your JPEG images by 4kb each at a minimum. For larger images, the file size reduction is greater.
The ICC Profile is ticked by default when Saving for Web in Photoshop. This embeds colour profile information in the image (for display in calibrated monitors or printing), however most browsers cannot read ICC profiles so this information is redundant.
More often than not ticking the ‘Progressive’ download option will also reduce file size.
Its all about crunching down the numbers for faster download times and more successful websites!
