Base64 Encode/Decode

Convert text to Base64 and back.

Loading tool…

Encode text to Base64 or decode Base64 back to readable text. Base64 is commonly used for safe transport of data in APIs, tokens, and configuration files. It is not encryption — it does not secure data, it only transforms it.

How to use

  1. Paste input text or Base64 string.

  2. Choose encode or decode.

  3. Review output.

  4. Copy the result.

FAQ

  • Is Base64 secure? No, it’s reversible and not encryption.

  • What is it used for? Transporting binary/text safely in systems.

  • Why does decoding fail? Input may not be valid Base64.

  • Can I encode files? This tool is mainly for text unless file mode exists.
