What is Base64 Encode?

Base64 Encode is a convenient tool that converts text data into ASCII string format. It's widely used for safely transferring text in various environments such as web applications, API communications, and email. With this tool, you can easily convert any text data into a ready-to-use Base64 format.

Key Features

  • Real-time Conversion: Displays encoding results instantly as you type
  • Multi-line Processing: Option to encode each line individually
  • URL-safe Support: Supports conversion to URL-friendly Base64 format
  • Simple Operation: Intuitive interface for easy encoding

How to Use Base64 Encode

  1. Enter Text: Input the data you want to encode in the left text area
  2. Set Options: Choose options like "Encode line by line" or "Convert to URL-safe format" as needed
  3. Automatic Conversion: Your text is automatically encoded in real-time, with results shown on the right
  4. Copy Results: Copy the encoded text from the right text area for your use

About Encoding Options

Encode Line by Line

Base64 encoding normally converts the entire text including newline codes as a single unit. When this option is enabled, the input text is split at each newline, and each line is encoded individually.

Use Cases:

  • When you need to encode multiple data items at once
  • Processing data like CSV where each line has meaning
  • When individual Base64 strings are needed for each line

Convert to URL-safe Format

Standard Base64 encoded results may contain characters like "+" and "/", which can cause problems when used in URLs. When this option is enabled, encoding is performed in a URL-safe format (replacing "+" with "-" and "/" with "_").

Use Cases:

  • Using Base64 data as URL parameters
  • Including Base64 data in web application query parameters
  • When data needs to be sent as part of a URL

Base64 Use Cases

  • Web Applications: Embedding text data directly in HTML
  • API Data Transfer: Safely transmitting text with special characters
  • Data Encryption: Protecting text when combined with other encryption methods
  • Email Communication: Sending encoded text data
  • Authentication Tokens: Used in authentication tokens such as JWT

How Base64 Works

Base64 encoding represents text data using only 64 printable ASCII characters. Specifically, it uses A-Z, a-z, 0-9, "+", "/", and "=" for padding.
