Tools and Web apps

Miscellaneous tools and small web apps to solve random problems. Mostly pretty prototypey and low-polish but, hey, sometimes you just need function rather than form.

Image to Data URL Converter. Get an image as a data URL! This makes it easy to embed images into HTML and Markdown rather than having to link out to some kind of host.
Single-Pixel Images. Get a copy-paste-able, single-color, single-pixel, HTML <img> element or image, for use as a placeholder.
Screen Size. Given a screen's diagonal (how the manufacturers always provide that information), get its width and height based on the aspect ratio.
Compare Lists. Sometimes I need to quickly get a union, intersection, or diff between some lists, and be able to easily copy them in a ready-to-use format. This little tool helps with that.
Input Detector. Sometimes I'm not sure what the browser will detect as a mouse/keyboard input, so having something to display it can be handy.
Clipboard Content Display. I'm often writing custom paste-handling for stuff copied from other applications, so being able to see what they put into the clipboard (including every MIME-type) is super useful.
Page Preview Generator. Used by this site to create social images for each page on this site, via Playwright. No real use case outside of that.
