<p>JPEGs seems like the right way to go, but at 90% there is a noticeable loss of sharpness and JPEG artifacts appear, both of which are more prominent the smaller the resolution.</p>
<p>I used the same tool (squoosh) to generate more high quality JPEGs, paying attention to how each resolution responded to a certain quality setting.</p>
<p>In the end I had to use values between 94 and 98 in order to ensure there is no noticeable difference with the original PNGs.</p>
<p>This brings up the total file size to 17.4 MiB, which I think is still fine, especially given that this is our default wallpaper for an LTS release.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R31 Breeze</div></div></div><br /><div><strong>BRANCH</strong><div><div>more-hq-next (branched from master)</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D27045">https://phabricator.kde.org/D27045</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>wallpapers/Next/contents/images/1024x768.jpg<br />
