A .B64 file usually contains Base64 text instead of raw bytes, meaning a real file such as a PDF, image, ZIP, or audio has been converted into safe printable characters for transport through systems that might corrupt binary, so when opened in a text editor you’ll see long runs of Base64 symbols—letters, numbers, `+`, `/`, and padding `=`—sometimes wrapped in certificate-style headers or MIME blocks, and decoding restores the original bytes, with common fingerprints like `JVBERi0` for PDFs or `iVBORw0` for PNGs, and remembering that Base64 adds size and offers no encryption or compression.

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.

Calling a .B64 file "text with Base64 data" means you’re seeing a readable stand-in for a PDF/PNG/ZIP’s underlying bytes, because ordinary binary can be damaged by systems that reject or alter non-printable characters, and Base64 avoids this by encoding them into a safe alphabet, requiring a decode step to reconstruct the original file.

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 usually holds Base64-encoded text made of characters `A–Z`, `a–z`, `0–9`, `+`, `/`, and sometimes `=`, representing the exact bytes of an original file like a PDF, image, ZIP, or DOCX; it may appear as one long line or many wrapped lines, and sometimes includes PEM-style or MIME-style headers, but regardless of formatting, the text must be decoded to recreate the real binary file.

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.
