How to use this tool · examples & limitations
Convert pixel values to REM units with a configurable base.
Getting a reliable result
Adjust one style property at a time, inspect the preview and copy the CSS into a test element.
Limitations to check
Verify the result on small screens and with keyboard navigation. A visual preview alone is not an accessibility audit.
