Scratching my own itch. I had to do this for showing information on ZX Spectrum games. So thought I'd turn it into a useful tool for other people to use.

Hi everyone, I build some "online" converters as a side project in the last weeks. The difference to existing conversion websites is, that my converters don't upload your files. Everything happens in your browser on your device (with the help of a lot of great Open Source Javascript libraries). I think privacy is an essential feature for a service like this, so my converters also don't use google analytics or any other form of tracking (in fact they use no external resources at all). I started this because I ended up with some .heic files from my iPhone and had to use ImageMagick every time…

I recently built a new template for my rather basic WordPress blog. I wanted to avoid using px units wherever possible, so that I could have a design that would scale uniformly across multiple device resolutions. It started as an experiment, to see how far I could get without px units. The more I learned, the more excited my campaign to eliminate px from the stylesheet. I ended up eliminating px units entirely. Everything is sized with vw units (relative to the width of the viewport). The last remaining px units were sizing standard Facebook and Twitter buttons. I got frustrated by not being…
