Base64 Encoder / Decoder
Encode text and files to Base64 or decode Base64 strings back to readable format. Essential for embedding data in URLs, APIs, and configuration files.
What is Base64 encoding?
Base64 encoding converts binary or text data into ASCII characters. It's commonly used to embed images in HTML/CSS, transmit data over protocols that only support text, or encode credentials in HTTP headers.
Embed Data Anywhere
Base64 encoding is essential when you need to include binary data (like images or files) in text-only contexts. For example, you can embed an image directly in HTML using a data URI: data:image/png;base64,.... This eliminates external HTTP requests and keeps everything self-contained.
API Credentials & Headers
Many APIs require credentials to be Base64 encoded in the Authorization header. For example, HTTP Basic Authentication uses the format Basic base64(username:password). Use this tool to quickly generate the correct header value.
Debug Encoded Tokens
Some systems encode configuration data, session tokens, or cookies in Base64. If you're debugging an application and see a mysterious Base64 string, decode it here to reveal the actual content (assuming it's not also encrypted).
