What is a 67 file

67 files mostly belong to Adobe Acrobat Reader.

File Format: *.67 files contain data in the Portable Document Format (PDF). Though the extension is non‐standard, these files keep the same internal structure as regular PDF files.

The document holds fixed page layouts, embedded fonts, and images so that it appears the same on different systems. Key details sourced by FilExt.com include:

  • Internal Structure: Organized with objects, streams, and cross‐reference tables similar to typical PDFs.
  • Viewing: Best opened with Adobe Acrobat Reader, ensuring proper display of text and graphics.
  • Usage: Used for sharing finalized documents without risk of accidental changes.

FilExt.com tip: If the file does not open as expected, renaming the extension from .67 to .pdf or setting Adobe Acrobat Reader as the default program can help.


Files with the extension 67 are often also jpg images or pdf documents, but zip compressed archives or medical images such as DICOM are also common. Use the Online 67 File Viewer on this page to find out the file format being used, and to view your 67 file.
