Google constantly harps on optimizing images, but Tumblr blindly reuses images that its users hand it. This makes me sad.&quot;&lt;p&gt;There are tons of valid uses for the color profile and other metadata in PNG files.   Generally, I &lt;i&gt;don&apos;t&lt;/i&gt; want services dicking with this stuff (in some cases I don&apos;t care, but I don&apos;t want the service to decide when I do or don&apos;t because it is bound to decide wrong some of the time, so they should just leave my data alone).&lt;p&gt;Onus should be on the content developer to save the image in a proper format and strip all metadata that isn&apos;t required.  I don&apos;t want services I use stripping this stuff willy-nilly.  Perhaps I &lt;i&gt;want&lt;/i&gt; accurate color profile data in my PNGs so my tumblr followers can make accurate prints.  Perhaps I &lt;i&gt;want&lt;/i&gt; geolocation EXIF data in there because my blog is read by people who want to see this data, etc.&lt;p&gt;tl;dr -- Don&apos;t listen to this guy, Tumblr (or anyone else).  He makes the classic mistake of &quot;because something isn&apos;t important to me, it has no use&quot;.</text></comment>

Does the website just need a good PNG optimizer and hope nothing breaks too bad, and if it does it&apos;s only an image?</text></comment>
