About Base64/Binary File Converter

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. It is commonly used to transfer files securely over text-based networks (such as inside JSON API endpoints or email attachments).

This converter allows encoding raw document bytes to Base64 formats or decoding data blocks back into standard downloadable binaries client-side. The operations occur completely in-browser without uploading file data to any server.
