About Base64 Encode / Decode

The Base64 Encode / Decode tool converts plain text into Base64-encoded strings and decodes Base64 data back into readable text. Base64 encoding is commonly used when handling binary data in APIs, email systems, and authentication headers.

Example

Input: Hello World
Base64 Encoded: SGVsbG8gV29ybGQ=
Decoded Output: Hello World

How to use it

• Step 1: Paste your text or Base64 string into the input box.
• Step 2: Choose Encode or Decode.
• Step 3: Copy the converted output instantly.

Who is this tool for?

This tool is helpful for developers, API testers, and SEO professionals working with encoded payloads or data transmission. If you’re extracting encoded values from text, try the Extract Between tool as well.

Why use Base64 encoding?

Base64 ensures data remains intact when transferred through systems that only reliably handle text content, such as URLs, headers, or JSON payloads.
