If you like to add some vintage like retro game feeling to your website, try use pixel art images might be a good idea. Here’s a quick howto.

Install GIMP

GIMP is an open source image processing program available on macOS, Linux and Windows. Visit https://www.gimp.org/ to download and install.

If you are like me who uses macOS and have the mighty homebrew package manager installed, simply run:

brew install gimp

Start Converting

Start the gimp, open your image-to-be-converted, then from the menu select Filters/Blur/Pixelize...

On the dialog box, you want to adjust Block Width and preview the results.

That’s it!
