Features & Capabilities

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.

🛠 Features

Real-time conversion — result updates as you type
Configurable root font size (10px, 16px, 18px — your call)
Quick-pick buttons for common values like 8, 12, 16, 24, 32
Reference table with 20 pre-calculated PX/REM pairs
One-click copy to clipboard
Formula display so you always see the math
Works fully offline — no internet ever needed

🔒 Zero data collection. No analytics, no tracking, no network requests, no ads — ever. The only permission used is storage, to remember your root font size locally.

Is PX to REM Converter Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PX to REM Converter does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

PX to REM Converter is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
