Extract text from URF files
To convert your URF file to another format, you need Apple AirPrint or other Raster Image software.
To convert other file formats to the "Print Spool File" file type, you need software like Apple AirPrint or a similar tool.
The .urf extension most commonly identifies the Universal Raster Format (often called Unirast), a proprietary raster image format developed by Apple for its AirPrint technology. These files essentially serve as "digital paper," containing a bitmap representation of a document prepared for driverless printing via IPP (Internet Printing Protocol). Users typically encounter .urf files when recovering failed print jobs from system spool directories (such as /var/spool/cups on macOS or Linux) or when analyzing network traffic to debug printer communication.
Because .urf is designed strictly as a machine-readable stream for printer hardware, it is not supported by standard image viewers or web browsers. You cannot simply double-click to view the content. The files are often large and uncompressed or use specialized compression (like PackBits or Apple's proprietary algorithms), making them difficult to handle without specific tools. To view the content of a print job, the most practical solution is converting the .urf file to a standard PDF for multi-page documents or PNG for single-page image inspection. Note: If your file is related to industrial automation, it may alternatively be a UniTek motor controller file, which is strictly data-only and requires proprietary engineering software.
Convert.Guru analyzes your URF file, detects the exact format, and lets you read the text inside.
Users also converted UDF, PBF, BYTES and ROOT files.
If you want to convert URF file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Apple AirPrint or similar software from the "Printer Raster Bitmap" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to URF, try Apple AirPrint or another comparable tool in the "Printer Raster Bitmap" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our URF converter.
