Base64, URL & HTML Encoder
Base64 turns arbitrary bytes into 64 printable characters so they can travel through text-only channels like JSON, email and data URIs. Paste text to encode or decode it — plus URL percent-encoding and HTML entities — with correct UTF-8 handling in your browser.
What is Base64?
It maps every 3 bytes to 4 characters from A–Z, a–z, 0–9, + and /. The result is about 33% larger and is not encryption — anyone can decode it. It is used for data:image URIs, Basic auth headers and embedding binary in JSON. URL-safe variants swap +/ for -_.
This tool runs entirely in your browser. Your inputs and files are processed locally and are never sent to or stored on Kinetikatech servers.
