<p>Relevant also for this group. Internal libtiff has just been
patched with the changes mentioned below.<br>
</p>
<p>I'd recommend sticking with libjpeg-turbo (preferred option) or
IJG libjpeg 6b, 7.x or 8.x</p>

Hi,<br>
<br>
A word of caution for those using mozjpeg or IJG libjpeg 9d for
creating JPEG-in-TIFF files. It has been found that current
libtiff releases can generate non-conformant (mozjpeg case) or
broken (libjpeg 9d case) files. See
<a class="moz-txt-link-freetext" href="https://gitlab.com/libtiff/libtiff/-/issues/266">https://gitlab.com/libtiff/libtiff/-/issues/266</a> for more details.<br>
<br>
<a class="moz-txt-link-freetext" href="https://gitlab.com/libtiff/libtiff/-/merge_requests/254">https://gitlab.com/libtiff/libtiff/-/merge_requests/254</a> and
<a class="moz-txt-link-freetext" href="https://gitlab.com/libtiff/libtiff/-/merge_requests/255">https://gitlab.com/libtiff/libtiff/-/merge_requests/255</a> have been
merged with workarounds to make libtiff work with those JPEG
libraries.<br>
