Base64 Encode & Decode
A secure, browser-based tool to encode text and data into Base64 format, or decode Base64 back into its original form. Ideal for developers and data handling.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed image data directly into HTML or CSS, or to transmit binary data in text-based protocols like email or JSON. This tool provides a simple, reliable way to perform Base64 encoding and decoding directly in your browser. Because all operations are client-side, your data remains completely private and is never sent to our servers.
How to Use the Tool
- Input Data: Paste your text or Base64 string into the left-hand input box.
- Choose Direction: The tool defaults to "Encode". To decode, simply paste a Base64 string into the input box and click "Decode", or use the swap button () to switch modes.
- Convert: Click the "Encode" or "Decode" button. The result will instantly appear on the right.
- Copy the Result: Use the copy icon to grab the output.
Common Use Cases
- Web Development: Encoding small images or icons as Base64 data URIs to embed directly in CSS, reducing HTTP requests.
- API Interaction: Sending or receiving binary file content within a JSON payload by encoding it as a Base64 string.
- Troubleshooting: Decoding a Base64 string from a log file or API response to understand its original content.
- Basic Obfuscation: While not a form of encryption, Base64 can be used to obscure data from casual observation.
