What is a .jpf file?
A .jpf file is a JPX (JPEG 2000 part 2). This is an image format — a picture, drawing or graphic.
How to open a .jpf file
- GIMP (free) and IrfanView open a very wide range of image formats, including obsolete ones.
- XnView MP is the best bet for unusual or legacy image types.
- Your operating system's built-in viewer may work for mainstream formats.
The registry records this extension against JPX (JPEG 2000 part 2), so software from that family is the most likely match.
How to convert a .jpf file
- Open it in GIMP or XnView and export as .png (lossless) or .jpg (smaller).
