JPF File Extension

What is JPF file?

Files with JPF extension store graphics data, typically digital camera photos saved in JP2. JPF is similar to JPEG, but offers slightly better image quality and better compression resulting in smaller file sizes, comparable with JPEG files. It uses more effective yet more resource-heavy compression algorithm, which is one of the reasons for low popularity of JPF format compared to the most popular JPEG format.

What features offers JPF?

JPF standard offers a choice between lossy or lossless compression, just like PNG (JPEG is a lossy compression format). JP2 format also supports advanced interlacing algorithm, similar to that used by JPEG. The algorithm allow streaming image data in multiple passes to achieve progressively higher-detailed image.

How is data store in JPF files?

JPF data is organized using the following elements:

• packet streams (image),
• compression information.

JPEG 2000 standard allows for saving raw image data (as JPC files) without any additional information or metadata. Such information can be added to related JP2 files.
