Who we are
Built for developers who value privacy
base0x helps you move between binary, decimal, octal, hexadecimal, text, Base64, and URL encoding in the browser. Conversions run entirely on your device, so the values you type stay with you.
We focus on clarity, speed, and a calm interface — tools that stay out of the way when you need an answer and get back to work.
Client-side first
Encoding and number-base math happen in your browser. We do not upload the content you convert.
Practical coverage
From everyday hex ↔ decimal work to Base64 and URL encode/decode, the toolkit covers the conversions developers reach for most.
