Title: JPEG Version 1.02 Conversion
Post by: Rajasekaran on April 17, 2021, 05:53:46 AM
We need to Convert the Color TIFF into JPEG (version 1.02). We have tried to converting the above format using some application, the version is not coming correctly (version 1.01 is coming). Customer requirement is JPEG 1.02.

So Kindly let us know any option for converting this format.

Thanks in Advance.

Exiftool cannot convert images as it only edits metadata.

That said, I can't find any data on the web about there actually being any real differences between the two.  The only thing I found is that 1.02 allows for thumbnail images.  From page 3 of the JFIF 1.02 specification (https://www.w3.org/Graphics/JPEG/jfif3.pdf#page=3)
QuoteThis version, version 1.02, has only one extension defined:  an extension for defining thumbnails stored in formats other than 24-bit RGB

Do you have any info about what they need done and why they specifically need 1.02.  It seems to be a really obscure request.
