How to convert PNG to JPF
- Add your .PNG file - drop it in the box above or click to browse.
- Convert it to .JPF in a few seconds.
- Download your new .JPF file.
What to expect
- Lossless JPEG 2000 mode keeps pixels exactly; lossy mode discards some detail for smaller files.
- JPF/JPX is even less widely supported than JP2 - expect Safari-only browser display and limited app support.
- Alpha transparency can be kept, but not every viewer reads JPEG 2000 alpha reliably.
Frequently asked questions
Is PNG to JPF lossless?
It can be.
JPF is the extended JPEG 2000 Part 2 (JPX) format and, like .jp2, uses wavelet compression that supports both lossless and lossy modes, so lossless preserves the PNG pixels exactly.Why convert a PNG to JPF instead of JP2?
JPF/JPX is the extended Part 2 variant of JPEG 2000 with additional capabilities over plain JP2; it is used where those extensions are specifically required.
What opens a JPF file?
IrfanView (with its JPEG 2000 plugin) or XnView MP on Windows, and Preview on macOS. No major browser except Safari displays it, so converting to PNG or JPG is the simplest way to share it widely.
Does transparency survive the conversion?
JPEG 2000 supports an alpha channel, so PNG transparency can be preserved, though reader support for it varies.
