Hey Product Hunt 👋
Most px/em converters I found online either only went one direction, or quietly assumed em always means 16px, which isn't how em actually works, it's relative to the parent element's font size. So I built one that asks for your base font size upfront and gets the math right, in both directions.
The bulk mode came out of a real annoyance: converting a handful of values one at a time in a browser tab while migrating a stylesheet is tedious. This lets you paste a whole list and get every converted value back at once.
It's one tool in CSS Toolkit, a set of free CSS utilities I keep adding to. No signup, no account, runs entirely in your browser.
Would love to hear if there's a format for the bulk input (CSV, one-per-line, straight from a CSS file) that would make this more useful for how you actually work.
