Frequently Asked Questions
What is Base64 encoding used for?▼
Base64 is commonly used to encode binary data as ASCII text for safe transmission in emails, URLs, APIs, and data storage where only text is supported.
Does this tool support Unicode/UTF-8 characters?▼
Yes, our tool properly handles Unicode characters by using UTF-8 encoding before Base64 conversion.
Why do some Base64 strings end with = or ==?▼
The = characters are padding to make the string length a multiple of 4. They are required for proper Base64 format but can often be omitted in practice.
Can I encode files or images?▼
This tool is for text encoding. For files/images, you would need to read them as binary data first, which requires file upload functionality.
