About Base64 Encode File

Base64 Encode File is a free online tool that converts any file into its Base64-encoded data URL representation. This is useful for embedding images directly in HTML or CSS, including files in JSON payloads, or transmitting binary data through text-based protocols. The output includes the MIME type prefix, making it ready to use as a data URI in web projects.

All file processing happens entirely in your browser — your files are never uploaded to any server. The tool uses the FileReader API to read files locally and convert them to Base64 encoding. It works with any file type including images, PDFs, text files, and more.
