Websites need files that are small enough to not slow the page load

Web file sizes

File sizes for the web are quite different to file sizes for printing.

The issue with large files

The issue with uploading large files to your website is it will slow down your page load. Therefore it’s quite important to know how to optimise your images before adding them to your website. Here I’m going to tell you how.

Good sizes for image

It’s good practice to keep your images between 70kb – 100kb each image.

Also, size your images only as large as the width of the article, page, blog you are adding it to. For example if you are adding an image to the top of a blog post that is 400px wide just size your image with a width of 400 pixels (px).

dpi doesn’t matter, you can save your image at 72dpi or 300dpi, go for it (dpi is for printing not web).

ppi – Pixels per inch. This is also not important. It was kinda the industry standard till about 5 minutes ago, you know, the olden days. Screens can handle hudreds of pixels per inch these days. So go ahead and save with 72 ppi or 300 ppi.

Edit the original photo only

If you have by mistake sized your image too small, don’t try and ‘stretch’ it to make it larger. Go back and get the original file and start again. This will help to avoid a grainy look (pixelation/blurriness).
