Base64 Encoder & Decoder
How to use the Base64 Tool
Paste your text into the input box and click "Encode" to convert plain text into a Base64 string, or click "Decode" to convert a Base64 string back to human-readable text. Base64 is widely used to encode tokens, images, or transmit binary data. It processes directly in your browser without requiring server interaction.

How to Use
Enter text or a string into the input field. Select whether you want to encode to Base64 or decode from Base64. The conversion happens in real-time as you type.
Technical Deep-Dive: Base64 Data Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is widely used in web environments for embedding small images directly into CSS or HTML, encoding JWT payloads, and transmitting data over protocols that are designed to deal with textual data. Our tool safely handles UTF-8 character encoding before applying the base64 translation, ensuring that special characters and emojis are not corrupted during the encoding or decoding process.
FAQ
- Is Base64 encryption? No. Base64 is an encoding mechanism, not encryption. It provides no cryptographic security and can be easily decoded by anyone.
- Can I encode files? This specific tool is optimized for text and string payloads.
