Extract text from Progressive JPEG images (PJPEG)
To convert PJPEG images to another format, you need Google Chrome or other Raster Image software.
To convert other file formats to the "Progressive Bitmap Image" file type, you need software like Google Chrome or a similar tool.
A .PJPEG file is simply a standard JPEG image that has been encoded with "progressive" rendering. Unlike standard "baseline" JPEGs that load from top to bottom, a .PJPEG renders in multiple passes, starting as a blurry, low-resolution image and gradually sharpening as more data arrives. While this was a critical feature for the dial-up era, the specific .PJPEG file extension is non-standard and rarely used today. Most modern software saves progressive images with the standard JPG extension. Consequently, users run into issues where operating systems or applications fail to recognize the .PJPEG extension, leaving the file "orphaned" without a default viewer.
Because the format is mathematically a JPEG, you can sometimes simply rename the file to JPG to force it to open. However, this doesn't fix underlying metadata issues or guarantee the file isn't using an obscure encoding parameter. For maximum compatibility, the pragmatic move is to convert it. To fix file association errors on Windows or macOS, convert to standard JPG. If you need to use the image on a modern website with better compression, convert to WebP. For archiving or editing without adding further compression artifacts, converting to PNG or TIFF is recommended.

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 PJPEG converter.
