Optimizing Hugo Image Loading Time

Wed, 24 Jun 2026 00:00:00 +0000

As I’ve added more posts to charliehowlett.co.uk, the site has gradually accumulated lots of screenshots, photos, and short animations. I usually upload whatever media files I have available without first optimising them for web, which can increase site size and negatively impact page load times. At first I thought to simply enable the img-bot GitHub action to automatically optimise images, but unfortunately the service’s free tier does not extend to private repositories. So I spent some time implementing my own automatic image optimisation process.
