🔄 5 free converters · no signup · runs in your browser

Free Online Converters

Convert between the things you actually mix up: metric and imperial units, 150+ world currencies with live exchange rates, HEX/RGB/HSL colours, Base64 and URL encodings, and Unix timestamps to human dates. Each converter updates in real time as you type — no convert button, no page reloads, no account — so you get the answer before you have finished typing the question.

These are built for precision, not approximation. Unit conversions use exact standard ratios to many decimal places, the colour converter round-trips faithfully between formats, and the timestamp tool handles timezones and both seconds and milliseconds. Whether you are a developer decoding a payload, a designer matching a brand colour or a traveller checking a price, the conversion is exact and instant.

Converters — frequently asked questions

The currency converter pulls free live market rates and refreshes them regularly throughout the day. Rates are indicative mid-market values — your bank or card provider will add its own margin on real transactions.

Exact. Conversions use the standard defined ratios (for example 1 inch = 25.4 mm) and compute to many decimal places, so they are safe for engineering, cooking, fitness and school work alike.

Everything except live currency rates runs entirely in your browser, so units, colours, Base64 and timestamps keep working even on a flaky connection — and every tool is touch-friendly on phones.

We built all of these. We can build yours.
