Base64 Encoder & Decoder – Encode and Decode Text Online

Base64 Encoder & Decoder Tool

Base64 is a widely used encoding method that converts text into a safe, text-based format. It is commonly used in web development, APIs, email systems, authentication headers, and data storage. This Base64 encoder and decoder tool is designed to handle both encoding and decoding tasks quickly and accurately.

You can enter text on the left to encode it into Base64 or paste a Base64 string on the right to decode it back into plain text.

Encode Text to Base64

The encoding section allows you to convert normal text into a Base64-encoded string. You can select the source character set before encoding to ensure accurate results. This is especially important when working with international languages or special characters.

Supported source character sets include:

1. UTF-8 (default)
2. UTF-16 (LE & BE)
3. UTF-32 (LE & BE)
4. ASCII and MacRoman
5. ISO-8859 variants (Latin, Arabic, Greek, Hebrew, Turkish, and more)
6. Many More...

Once encoded, the Base64 output can be used safely in URLs, APIs, headers, and configuration files.

Decode Base64 to Text

The decoding section allows you to convert Base64-encoded data back into readable text. Simply paste the Base64 string, select the target character set, and decode it instantly.

This feature is useful when working with API responses, encoded payloads, authentication tokens, or stored Base64 data.

Multiple Character Set Support

Unlike basic Base64 tools, this encoder and decoder supports more than 50 character sets. This ensures accurate encoding and decoding across different languages, platforms, and systems.

Character set selection helps prevent data corruption and ensures correct text representation.

Use Cases for Base64 Encoding

This tool is useful for many real-world scenarios, including:

1. Encoding API payloads and headers
2. Decoding Base64 responses from servers
3. Handling text with special or non-English characters
4. Debugging encoded data
5. Preparing content for secure transmission

Fast, Accurate, and Easy to Use

The tool processes data instantly without page reloads. Clear input fields and one-click actions make encoding and decoding simple, even for non-technical users.

You can switch between encoding and decoding without losing your data.

Secure and Privacy Friendly

All encoding and decoding happens directly in your browser. No text is stored, logged, or shared. This makes the tool safe for working with sensitive or confidential data.
