How to convert JPF to JP2
- Add your .JPF file - drop it in the box above or click to browse.
- Convert it to .JP2 in a few seconds.
- Download your new .JP2 file.
What to expect
- This is a Part 2 to Part 1 down-convert: Part 2-only features such as compositing layers and extended colour spaces are dropped.
- Pixel quality is unchanged - you are re-wrapping the same wavelet data, not re-compressing the image.
- Archival and geospatial JPF files may carry XML metadata boxes or extended ICC profiles that tools silently drop when writing JP2.
Frequently asked questions
Is .jpf the same format as .jp2?
Both are JPEG 2000, but .jp2 is Part 1 (the base standard) and .jpf is Part 2 (JPX), which adds optional extensions. A JPF may or may not open in a plain JP2 reader depending on which Part 2 features it uses.
Will the image look different after converting?
Not if the JPF only uses Part 1-compatible features - the wavelet image data passes through unchanged. If Part 2 compositing or colour-space extensions were active, those are lost and the result may render differently.
Why does my software open .jp2 but not .jpf?
The software likely supports only JPEG 2000 Part 1. Full JPX (Part 2) support requires a complete OpenJPEG or Kakadu implementation; tools with confirmed Part 2 support include ImageMagick and XnView MP.
Is converting JPF to JP2 lossless?
At the pixel level, yes - the wavelet data is re-wrapped, not re-encoded. If the original JPF was lossy, the JP2 carries the same lossy data; if it was lossless, the JP2 is also lossless.
