				<description>&lt;p&gt;Hugo 0.165 encodes AVIF. Nothing to install: it is in the binary, alongside&#xA;JPEG, PNG, WebP, GIF, TIFF and BMP.&lt;/p&gt;&#xA;&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; class=&#34;chroma&#34;&gt;&lt;code class=&#34;language-go-html-template&#34; data-lang=&#34;go-html-template&#34;&gt;&lt;span class=&#34;line&#34;&gt;&lt;span class=&#34;cl&#34;&gt;&lt;span class=&#34;cp&#34;&gt;{{&lt;/span&gt;&lt;span class=&#34;w&#34;&gt; &lt;/span&gt;&lt;span class=&#34;nx&#34;&gt;$img&lt;/span&gt;&lt;span class=&#34;na&#34;&gt;.Resize&lt;/span&gt;&lt;span class=&#34;w&#34;&gt; &lt;/span&gt;&lt;span class=&#34;s&#34;&gt;&amp;#34;900x avif q60&amp;#34;&lt;/span&gt;&lt;span class=&#34;w&#34;&gt; &lt;/span&gt;&lt;span class=&#34;cp&#34;&gt;}}&lt;/span&gt;&#xA;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;The quality numbers do not mean the same thing between formats. AVIF at q80&#xA;aims far higher than JPEG at q80 and charges you for it, which is why the&#xA;list below has AVIF three times.&lt;/p&gt;&#xA;&lt;p&gt;Click one to see it full size, then step through with the arrows. The&#xA;pictures do not move between steps, so any difference is a difference and&#xA;not your eye relocating.&lt;/p&gt;</description>
