What is a Base64 Encoder?

The Base64 Encoder is an online tool that allows you to convert text and images into Base64 format. Base64 encoding is commonly used to safely transmit or store data in environments that only support plain text, such as JSON, HTML, CSS, or API communication.

Why Use Base64 Encoding?

Many systems cannot handle binary data directly. Base64 encoding converts binary content into a readable, ASCII-safe string so it can be embedded or transferred without issues. This makes Base64 ideal for embedding images in web pages, sending data over APIs, or ensuring special characters are preserved in text-based systems.

This tool separates text and image output, making your workflow clearer and more organized.

How It Works

There are two encoding modes available:

1. Encode Text
   • Write or paste your text into the input box.
   • Click the “Encode Text” button.
   • The Base64-encoded text will appear in the dedicated Text Output box.
   • You can copy the encoded string using the “Copy” button.
2. Encode Image
   • Select an image file from your device.
   • Click the “Encode Image” button.
   • The image will be converted into a Base64 data URL.
   • The result will appear in the separate Image Output box.

Common Uses of Base64

• Embedding images directly into HTML or CSS files
• Sending files or text through APIs that only accept plain text
• Encoding images for email attachments
• Storing non-ASCII text safely in databases
• Converting small icons or assets to inline Base64 for performance optimization
