How to Encode and Decode Base64?

Base64 is a vital encoding scheme for developers. Convert text to Base64 to safely transmit binary data, or decode it back to read the original content.

  1. To Encode: Enter your plain text in the input box and click "Encode". The resulting Base64 string will appear in the Result box.
  2. To Decode: Paste a Base64 string (e.g., usually ends with `=`) into the input box and click "Decode" to reveal the original text.
  3. Copy Results: Use the "Copy" button to grab the output instantly.

Common Uses for Base64

  • Embed Images: Developers encode images to Base64 to embed them directly in HTML/CSS (Data URIs) to reduce HTTP requests.
  • Email Attachments: Email protocols (SMTP) use Base64 to transmit non-text attachments.
  • Basic Obfuscation: While not encryption, it hides data from casual glance (e.g., passing simple state in URLs).

Privacy & Security

Important: Base64 is NOT encryption. It is encoding. Anyone can decode it. Do not use it to hide passwords.

Client-Side Only: Your data processing happens entirely in your browser. CodeCoffeeTools does not verify or store your strings.

Frequently Asked Questions

Why does the output end with "="?

The `=` sign is padding. Base64 strings must have a length divisible by 4. If the data falls short, `=` is added to fill the gap.

Can I convert images here?

This tool is text-to-text. For image-to-base64 conversion, please check our upcoming "Image Tools" section.

About Base64

Base64 is a binary-to-text encoding scheme. It's commonly used to encode data that needs to be stored and transferred over media that are designed to deal with textual data.
