A .B64 file is commonly a Base64-encoded version of another file, used because emails, logs, and APIs often can’t handle raw bytes, so editors show long Base64 sequences—plus optional padding or headers—and decoding regenerates the original PDF, image, ZIP, or audio, with familiar clues like `iVBORw0` (PNG) or `JVBERi0` (PDF), and remembering Base64 increases size while offering no encryption.

A .B64 file is commonly a text-safe container for binary data so items like PDFs, images, or ZIPs can move through systems that prefer plain text, such as email where attachments are Base64 under the hood, APIs that return files as Base64 inside JSON, or developer workflows that embed icons, certificates, or small blobs directly into HTML/CSS or config files, and many backup/import tools also use it so data can be pasted or stored safely, with the core idea being that the `.b64` file is decoded later to restore the original binary.

When we refer to a .B64 file as text representing binary, we mean the file is not the original PDF/image/ZIP but a textified byte sequence created so binary won’t be corrupted in email, logs, or other text-only paths, and decoding the Base64 restores the exact bytes of the real file.

You’ll see .B64 files whenever tools need a corruption-proof text version of a file, such as email payloads encoded in Base64, APIs delivering PDFs or images as Base64 strings, developers embedding certificates or small images in config or HTML/CSS, and backup tools exporting portable text blobs, with `.b64` serving as the wrapper that’s decoded later.

A .B64 file is a container for Base64-formatted data consisting of characters like letters, digits, plus signs, slashes, and optional padding, arranged either as one long stream or many short lines, and may be surrounded by PEM-style or MIME headers; decoding this text restores the actual binary file in its proper form.

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.
