Can we have a multi-page JPEG image?

Can we have a multi-page JPEG image?

I have a TIFF image file with multiple pages, but it's too big and first thing comes to mind is to change it to JPEG format, however in JPEG I can see only first page. Therefore I realized only TIFF format allows multiple images in one file. Is that true?

Now I tried to apply different EncoderParameters to reduce the size of TIFF file but no luck. Has someone worked on this issue before? How did you manage to reduce the size of TIFF image?

Encoder.Quality does not seem to work with TIFF at all. EncoderValue.CompressionLZW is the best option to reduce the size, but I still want to reduce the size more.

Changing dpi to 50 reduced the size, but that made image too blurry.

Thanks for any help.

It is possible througt the use of XMP. Android is using this for their new UltraHDR format which is backwards compatible with standard jpeg.

There is a library for it. https://github.com/google/libultrahdr

JPEG is technically a image compression, the JPEG file type is actually JFIF which does not support multi-frames. TIFF is an image container that does support the JPEG compression algorithm though, so you should be able to save the TIFF file as small as saving each page as a seperate JPEG added up.

Here is a stackoverflow post that goes into more detail on how to achieve this:
