4 basic tips for preparing images for the web

When getting images ready to go on to your website, it’s not as simple as just uploading a photograph straight from your digital camera. Why? Because raw digital camera images are approximately 5MB each, and for images to download fast on your website you need them to be about 1/50th of that!


You can still have good quality images without a giant file size.

1. Resolution

Web images should be 72dpi. Higher resolutions are only necessary for print.

2. Dimensions

As a rule, you won’t ever need your website images to be wider than about 1000 pixels. For standard photo galleries, it’s a good idea to save your photos with the dimensions of approximately 900 pixels wide by 600 pixels high.

3. File size

The smaller, the better. As a rule, try and keep them well below 100kb.

4. RGB, not CMYK

Digital files use RGB (red, green, blue) colour mode, unlike print files which use CMYK (cyan, magenta, yellow, black)

Not sure how to edit your images?

If you don’t have a graphics software program, you can use Paint to do the simple things like resizing images. For more in depth image editing, you can consider a free image software such as Gimp.
