Base64 Encode / Decode
Encode text to Base64 or decode it back — standard or URL-safe, UTF-8 aware, live in your browser.
How to use
Pick Text → Base64 to encode, or Base64 → Text to decode. URL-safe swaps +/ for -_ and drops padding, for tokens that ride in URLs. Full Unicode (UTF-8) is handled, and Swap moves the result back into the input. Nothing is uploaded.
