PX to REM Converter szerző: Markeir

Instantly convert pixel values to REM with a custom base font size. Fast, clean, and built for developers. No ads, no tracking.

PX to REM Converter — your developer toolbar shortcut for instant CSS unit conversion.

Stop the mental gymnastics. Click the icon, type a pixel value, and instantly see the REM equivalent — right from your Chrome toolbar.

⚡ What it does

Type any pixel value and the extension immediately shows you the exact REM equivalent based on your configured root font size. The default is 16px — matching the browser — but you can set your project's actual base and it's remembered automatically.
