Fast Base64 & URL Encoding/Decoding

Great for developers, QA, and content work. Encode data for transport (Base64) or safely embed it in links (URL encode). All processing happens locally in your browser for privacy.

🧪 Example

Input: Hello World!

  • Base64: SGVsbG8gV29ybGQh
  • URL: Hello%20World%21

Base64 / URL — FAQ

Is anything uploaded to a server?

No. Everything runs in your browser — private and instant.

Why does decoding fail sometimes?

Invalid or malformed input (e.g., wrong padding for Base64) can’t be decoded. Check the source string.

What’s the difference between Base64 and URL encoding?

Base64 converts binary/text to ASCII for transport; URL encoding replaces unsafe URL characters with percent-escapes.
