Any Google Font on Your ESP32 Display

Every time I put text on a TFT display with TFT_eSPI I end up staring at the same built-in fonts: chunky, jagged, and very 1980s. Which is a shame, because the library has been able to draw beautiful anti-aliased “smooth fonts” for years. The rendering was never the problem, the tooling was. The official way to make a smooth font involves installing the Processing IDE, editing a Java sketch, and running it again for every font at every size. The result is that most projects never bother. So I built something to fix that. fonts.atomic14.com is a free browser tool that turns any of 1,900+ Google Fonts (or your own TTF file) into fonts ready to use with TFT_eSPI, M5Stack/M5GFX or LVGL, with a pixel-exact preview of how they’ll look on your panel. Everything runs in your browser; no font ever gets uploaded anywhere. The rest of this post is about what’s actually inside these font files, and the handful of things worth knowing before you use them. What a “smooth font” actually is…
