Binary, ASCII, UTF-8
Encoding Explorer is a free, browser-based tool for converting between number systems and text encodings. It supports 21 conversions across binary, decimal, hexadecimal, ASCII, UTF-8, Base64, URL encoding, and Morse code — plus a text length and byte counter for quick sanity checks.
Everything runs instantly with no sign-up and no ads. Conversions are computed on request and are never stored on a server — your history is saved only in your own browser's local storage.
ASCII is a 7-bit encoding that only covers 128 characters — the basic English alphabet, digits, and a few symbols. UTF-8 is a variable-width encoding that can represent every character in Unicode, including accented letters, non-Latin scripts, and emoji, while staying backward-compatible with ASCII for the first 128 characters.
Yes. Encoding Explorer is free, requires no sign-up, and has no usage limits.
Conversions are computed on request and are not stored on the server. Your conversion history is saved only in your own browser's local storage, so it stays on your device and is never uploaded anywhere.
The backend runs on a free hosting tier that goes to sleep after a period of inactivity. The first request after it's been idle can take up to 50 seconds while it wakes back up; every request after that is instant.
Yes. The site is fully responsive and works on phones, tablets, and desktops.
