About this tool

Some contexts — embedding a small image directly in CSS or HTML, pasting binary data into a JSON payload, sending a file through a system that only accepts text — can't handle raw binary files and need it represented as text instead. This tool encodes any file into Base64 text, or decodes Base64 text back into the original downloadable file, covering both directions of the conversion that comes up constantly in web development and data interchange.
