How to convert JPF to TIFF
- Add your .JPF file - drop it in the box above or click to browse.
- Convert it to .TIFF in a few seconds.
- Download your new .TIFF file.
What to expect
- The conversion to TIFF is lossless - pixel values are decoded from JPF's wavelet compression and stored exactly in TIFF with no further quality loss.
- TIFF files are significantly larger than JPF; a 10 MB
.jpfcan become 50-100 MB uncompressed - choose LZW or ZIP compression in the save dialog to reduce size while staying lossless. - Some JPEG 2000 Part 2 (JPX) features such as extended colour spaces are not handled equally by all decoders; if colours look wrong, try Photoshop or ImageMagick, which handle ICC profiles most reliably.
Frequently asked questions
Will I lose image quality converting JPF to TIFF?
No - TIFF is a lossless format and the conversion simply decodes the JPF's wavelet data into pixels stored exactly as-is. Quality loss only occurs if you later save the result as JPEG.
Can I convert a 16-bit JPF to a 16-bit TIFF?
Yes - Photoshop, ImageMagick, and XnView MP all preserve 16-bit depth. In IrfanView, check the save dialog to confirm 16-bit output is not being downsampled to 8-bit.
Why is the TIFF so much larger than my JPF?
TIFF stores uncompressed or lightly compressed pixel data, while JPF uses high-ratio wavelet compression. Choosing LZW or ZIP compression when saving the TIFF typically reduces size by 30-60% while keeping it lossless.
My JPF opens fine but the colours in the TIFF look wrong.
The JPF may use a non-sRGB colour space, a JPEG 2000 Part 2 extension. Try converting with Photoshop or ImageMagick, both of which handle ICC profile conversion more completely.
