Works
Viewing, inspecting and verifying. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. File details, exact byte size and the detected signature are always shown.
How to open a .pfb file
Opening a PFB file usually means tracking down special software. It does not have to. Here is what the format really is, and a browser-based way to read one right now.
What is a .pfb file?
Printer Font Binary is a binary & system format developed by Adobe, first appearing in 1985. It is normally produced by Type 1 font distribution, pre-2000 print work.
The binary half of a Type 1 font, historically paired with a .pfm metrics file. Adobe ended Type 1 support in 2023, so these no longer load in current Creative Cloud applications.

Open a .pfb file in your browser
OpenAnyFile routes .pfb to its universal hex inspector, which inspects a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .pfb file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the universal hex inspector.
- Your PFB opens on its own viewer page: a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.
- Use fullscreen for a closer look, or download the file back out unchanged. Works the same on Windows, macOS, Linux, Android and iOS, because it is just a web page.
What you can and cannot do with it here
Does not work
Full-fidelity rendering. This extension has no standard structure, so you get a byte-level inspection rather than a rendered view.
No upload, and here is why that matters for {E}
Handing a .pfb file to a random conversion site means handing over a copy you cannot get back. OpenAnyFile parses the file locally instead — the same way special software reads it off your disk, except the reader happens to be a web page. Nothing is transmitted, so there is nothing to leak, log or subpoena. It also means it keeps working with your Wi-Fi switched off.
Frequently asked questions about PFB files
Can I open a .pfb file without installing special software?
Yes. OpenAnyFile's universal hex inspector runs in your browser, so you can read a PFB file with nothing installed. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. It will not replace the original application for editing, but it answers 'what is in this file' in seconds.
How can I check a file really is a PFB file?
Look at the first bytes rather than the extension. A genuine PFB begins with 80 01. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .pfb by mistake is easy to spot.
Is it safe to open a PFB file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .pfb file, exactly?
Printer Font Binary — an application/x-font-type1 format created by Adobe since 1985. The binary half of a Type 1 font, historically paired with a .pfm metrics file. Adobe ended Type 1 support in 2023, so these no longer load in current Creative Cloud applications.
Does the same viewer handle formats related to PFB?
Yes — the same engine also opens .dll, .doc, .exe, so you can compare related files without switching tools.
