Frequently Asked Questions
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. It's commonly used when binary data needs to be stored or transmitted over media designed to handle text.
Why use Base64 encoding?
Base64 encoding is used when you need to transmit or store binary data (like images, files, or certificates) in a format that only supports text, such as email, JSON APIs, HTML, or CSS.
Is my data stored or sent to a server?
No. All encoding and decoding happens entirely in your browser using JavaScript. Your data never leaves your device, and no data is sent to our servers.
