A .B64 file serves as a text-safe encoding of binary data, 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 serves as a text-mode transport for binary data which explains why email sends attachments as Base64, APIs return files in JSON strings, and developers embed icons or certificates directly into code or configurations, plus many backup tools export paste-ready Base64 blocks, with the end goal being that decoding restores the original binary content.

When we describe a .B64 file as a Base64 text wrapper, we mean the file isn’t the real PDF/PNG/ZIP itself but a text version of its byte stream, created because binary often gets corrupted in text-focused environments, so Base64 maps the bytes into safe printable characters that survive transfer, and decoding later restores the exact original file.

You’ll see .B64 files in places that must move binary through text-based channels, such as email attachments encoded for safe transit, APIs sending images or documents inside JSON, developers embedding icons or certificates into text formats, and export/backup tools creating copy/paste-friendly blobs, with `.b64` acting as a dependable wrapper until decoding restores the real file.

A .B64 file encapsulates binary data inside Base64 text with characters from its limited alphabet, optionally broken into lines and occasionally wrapped in PEM/MIME headers, and only becomes the actual usable file again once the Base64 is decoded back to raw bytes and saved properly.

A fast visual cue for a .B64 file’s decoded type is the prefix of the Base64 data—PDFs commonly start with `JVBERi0`, PNGs with `iVBORw0`, ZIP and Office files with `UEsDB`, and JPEGs with `/9j/`; this heuristic isn’t absolute when headers or truncation are involved, but in most real cases it correctly guides you to the proper extension once decoded.
