A .B64 file mostly functions as a Base64-encoded wrapper so the underlying binary (PDF, PNG, ZIP, audio, etc.) is expressed in safe characters suitable for email, configs, logs, or APIs, and opening it in a text editor reveals lines of Base64 characters plus possible padding `=` or headers like `-----BEGIN ...-----`, while decoding converts it back into the exact file, with telltale starts such as `UEsDB` hinting at ZIP/DOCX or `/9j/` hinting at JPEG, and Base64 making data larger without providing encryption.
A .B64 file functions as a safe text wrapper for binary content which is why email systems use Base64 to transport attachments, APIs send documents or signatures as Base64 strings in JSON, developers embed small resources like icons or certificates into HTML/CSS or config files, and migration/backup tools export data that can be pasted or stored easily, with decoding converting the Base64 back into the original file.

Saying a .B64 file is a Base64 text version of binary highlights that you’re looking at a safe, printable character set instead of the true PDF/ZIP/PNG, because binary isn’t reliable in text systems, and Base64 preserves it until you decode it back into the original usable bytes.
You’ll see .B64 files because Base64 is a dependable way to protect binary in text channels, making email attachments Base64-encoded, APIs returning files in JSON, developers embedding assets in scripts or configs, and migration tools producing copy/paste-safe dumps, all depending on decoding the `.b64` to recreate the original file.
A .B64 file encodes binary data using Base64 characters using the restricted alphabet (`A–Z`, `a–z`, `0–9`, `+`, `/`, `=`), sometimes split into multiple lines or kept continuous, and may include PEM/MIME wrappers around the payload, but the important part is that decoding the text yields the original file’s bytes, which must then be saved with the correct extension.
To quickly identify a .B64 file’s future form, check the opening Base64 prefix: `JVBERi0` typically marks a PDF, `iVBORw0` a PNG, `UEsDB` a ZIP-derived file (like `.docx` or `.pptx`), and `/9j/` a JPEG, and while exceptions exist—such as wrappers or partial data—this shortcut often provides the correct target extension after decoding.
