Frequently Asked Questions

What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into a string of ASCII characters. It is commonly used to embed images in HTML/CSS, transmit data over text-based protocols like email, and encode API keys.
Does Base64 support Unicode and UTF-8?
Yes. This tool uses the TextEncoder API to properly handle UTF-8 text before encoding to Base64, so characters from any language are supported.
Can I encode files?
Yes. Switch to File mode to encode any file to its Base64 data URI representation. This is useful for embedding images or other assets directly in web pages.
