color pickerBase64 is an encoding scheme that converts binary data (like images, files, or binary strings) into ASCII text format. It uses 64 characters (A-Z, a-z, 0-9, +, /) to represent any binary data, making it safe to transmit over text-based protocols like email, HTTP headers, or JSON APIs.
Base64 is an encoding, not encryption - it does not provide any security. Anyone can decode Base64 data back to its original form instantly. Never use Base64 as a security measure. Our tool processes data entirely in your browser - nothing is sent to any server.
