Encode text to Base64 or decode Base64 back to text instantly with our free online tool.
Encode sensitive information or decode Base64 strings with a single click.
Our Base64 tool allows you to easily encode text to Base64 format and decode Base64 back to readable text. Base64 encoding is commonly used for encoding binary data in email messages, web pages, and other applications where data needs to be stored or transferred in a text format.
What is Base64 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.
Is Base64 encoding secure?
Base64 is not encryption and provides no security. It's simply an encoding method that allows binary data to be represented as text.
Can I encode images with this tool?
This tool is designed for text encoding/decoding. For images, you would need to first convert the image to a data URI string.
Is there a limit to the text length I can encode?
There's no fixed limit, but very long texts may cause performance issues in your browser.
