Base64 Encode Online - Free & Privacy First Text Encoder | StringFlux

ABOUT BASE64 ENCODE
This tool lets you quickly encode any text into Base64 format, a widely-used encoding scheme that converts text into an ASCII-based representation. Base64 encoding is useful when text needs to be safely transmitted or stored in environments that only support plain text, such as JSON, XML, or URL parameters.
While Base64 is often associated with encoding binary data, this tool is specifically designed for text input only, ensuring a lightweight and privacy-friendly experience — all processing is done directly in your browser.
As part of the StringFlux toolkit, you can seamlessly chain this encoder with other transformations, like JSON escaping or URL encoding, to handle more complex data formatting workflows without switching tools.
If you need to decode Base64 back to text, check out our Base64 Decode tool.
FAQ
What is Base64 encoding?
Base64 encoding is a method of converting data into a text format using only ASCII characters with a 64-character alphabet. It is commonly used to encode data that needs to be stored or transferred over mediums that only support text, such as JSON, XML, or URLs.
Can I use this base64 encoding tool to encode binary data?
No, this tool is designed specifically for text input only. If you need to encode binary files like images or documents, you’ll need a specialized tool that supports file input.
Is Base64 encoding the same as encryption?
No, Base64 is not encryption. It is simply an encoding scheme that makes data suitable for text-based transmission, but it does not provide any data protection or confidentiality.
Is Base64 encoding reversible?
Yes, Base64 encoding is completely reversible. To decode Base64 back to the original text, you can use our Base64 Decode tool.
Does this tool support URL-safe Base64 encoding?
Not yet. This tool currently supports standard Base64 encoding only. However, we plan to introduce more options soon, including URL-safe Base64 encoding, which replaces + with - and / with _ to make the output safe for URLs.
Why would I need to encode text in Base64?
Base64 encoding is useful when you need to:
- • Embed data within JSON, XML, or HTML
- • Safely transmit text over text-only protocols
- • Convert data for inclusion in URLs (with URL-safe encoding)
Can I see an example of Base64 encoding?
Sure! For example, the text:
