Tools

This is a collection of small tools I've built during my years as a web developer. I started building websites in 1998, but didn't collect these tools until November 2007. The tools where on my different employers servers until December 2020. Then many old tools that I didn't find useful anymore were removed and the rest ended up on this address. And I have also built some new ones since then. This is an ongoing project. If you have an idea for a new useful tool, please let me know and I might build it! Contact me via any of my social media accounts.

If you find something useful, please feel free to use the tool as often as you need. You can even copy it somewhere else if you like.
