Base64 Encoder/Decoder
Encode and decode text to Base64 format securely in your browser.
About Base64
Base64 is a binary-to-text encoding scheme. It is commonly used to encode data (like images or files) so that it can be embedded directly into HTML/CSS files or sent via APIs that handle text better than binary data. It is **not** encryption and should not be used to secure sensitive data.
How to Use This Tool
Follow these simple steps to get the most out of the Base64 Encoder/Decoder.
Paste your text into the input field.
The tool converts it to a standard ASCII Base64 string.
Use 'Decode' to convert Base64 back to plain text.
Copy the result.

What is Base64?
Base64 represents binary data in an ASCII string format by translating it into a radix-64 representation.
Common Uses
- Data URIs: Embedding small images directly into CSS or HTML to reduce HTTP requests.
- Email Attachments: MIME uses Base64 to transmit non-text attachments.
- APIs: Sending binary data (like files) over JSON APIs.
Security Warning
Base64 is encoding, not encryption. Someone with a decoder can easily read the original message. Do not use it to hide passwords or sensitive keys.
