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 what you need when binary data has to travel through a text-only channel. An image can be embedded straight into HTML with a data URI:data:image/png;base64,..., which removes an HTTP request and keeps everything self-contained.
API credentials and headers
Many APIs require credentials to be Base64 encoded in the Authorization header. HTTP Basic Authentication uses the formatBasic base64(username:password). Use this to generate the correct header value.
Debug encoded tokens
Some systems encode configuration data, session tokens or cookies in Base64. If you are debugging an application and see a mysterious Base64 string, decode it here to reveal the actual content, assuming it is not also encrypted.
