Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into a sequence of printable ASCII characters. It is commonly used to embed binary data in text-based formats like JSON, XML, HTML, and email.
How do I encode text to Base64?
Select "Encode" mode, type or paste your text into the input area, and the Base64-encoded result appears instantly. You can then copy it with the Copy button.
Does this tool support Unicode and special characters?
Yes! This tool fully supports UTF-8 encoding, so you can encode and decode text containing Unicode characters, emojis, and special symbols without any issues.
Is my data safe?
Yes! All processing happens entirely in your browser. Your data is never sent to any server. No data is collected, stored, or transmitted.
What is URL-safe Base64?
URL-safe Base64 replaces "+" with "-" and "/" with "_", and removes trailing "=" padding. This variant is safe to use in URLs and filenames. It is commonly used in JWT tokens and web APIs.
