<h1>After Drupal 8.6.x</h1>

In your <code>THEME.info.yml</code> add a line like <code>logo: logo.png</code>. You need to clear cache for Drupal to detect this change.

<h1>Before Drupal 8.6.x</h1>

Default logo file has now become <code>logo.svg</code> in Drupal 8. However, to use <code>logo.png</code> or something else, you need to add custom settings definition in your theme. To do this, add the following lines to <code>config/install/THEME.settings.yml</code> file in your theme folder (replace <code>THEME</code> with your theme's machine name).

<pre><code>logo:
 path: 'themes/THEME/logo.png'
 use_default: false
</code></pre>

After doing this, you must reinstall your theme if already installed. The file asks Drupal to install the given settings when the theme is installed. Hence, when you install the theme, the logo <code>path</code> parameter gets saved to the database and the default logo is disabled by the <code>use_default</code> parameter.

blocks|key|5543050|text|对于常规主题，您只需转到“外观”页面，转到“设置”选项卡并取消选择Use+the+logo+supplied+by+the+theme。出现的上传表单允许上传另一个图像。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5543051|📷|atomic|5543052|如果您正在实际构建主题，并希望提供默认图像，请参考其他答案之一。|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://i.stack.imgur.com/lsT7t.png|imageAlt^0|X|Y|0|0|1|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@$9|W|A|X|1|Y]]|E|$]]|$1|I|3|J|5|6|7|Z|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q|R|-4]]]]

For regular themes, you can just go to the appearance page, go to the settings tab and deselect <code>Use the logo supplied by the theme</code>. The upload form that appears allows to upload another image instead. 

<a href="https://i.stack.imgur.com/lsT7t.png" rel="noreferrer"><img src="https://i.stack.imgur.com/lsT7t.png" alt="steps"></a>

If you are actually building the theme and want to supply a default image, please refer to one of the other answers.

As of Drupal 8.6 your contrib or custom theme (say it's called mythemename) can easily define the default logo in its <code>mythemename.info.yml</code> file:

<code>
logo: images/acme-logo-stacked.png
</code>

See <a href="https://www.drupal.org/docs/8/theming-drupal-8/defining-a-theme-with-an-infoyml-file#logo" rel="nofollow noreferrer">https://www.drupal.org/docs/8/theming-drupal-8/defining-a-theme-with-an-infoyml-file#logo</a>

Note that to be used the logo <code>use_default</code> setting must be true.

blocks|key|5542879|text|在Drupal+8中，默认的徽标需要一个SVG文件。您仍然可以使用带有自定义徽标的PNG文件，或者如果主题有额外的自定义设置来支持非SVG默认标识。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5542880|这是在主题的默认徽标类型是SVG.中报告的，Drupal8.0.0-Beta5的变更记录。|5542881|正如注释中所报告的，您还可以在主题设置文件中使用以下内容。|5542882|logo:
++path:+'themes/THEME_NAME/logo.png'

In Drupal 8, the default logo needs to be a SVG file. You can still use a PNG file with a custom logo, or if the theme has <a href="https://www.drupal.org/node/177868" rel="nofollow noreferrer">extra custom settings</a> to give support to non-SVG default logos.

This is what reported in <a href="https://www.drupal.org/node/2410787" rel="nofollow noreferrer">The default logo type for themes is SVG</a>, a change record for Drupal 8.0.0-beta5.

As reported in the comment, you could also use the following in the theme settings file.

<pre><code>logo:
 path: 'themes/THEME_NAME/logo.png'
 use_default: false
</code></pre>

This would automatically use a custom logo without setting it from the UI.

blocks|key|5543096|text|在Drupal8.6中，这可以在您的.info.yml文件中设置如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5543097|logo:+'images/MY_THEME_LOGO.png'|code-block|syntax|javascript|5543098|主题路径自动添加到src路径中。|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|K|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|L|8|@]|9|@]|A|$]]]|I|$]]

In Drupal 8.6 this can be set in your .info.yml file as follows:

<pre><code>logo: 'images/MY_THEME_LOGO.png'
</code></pre>

the theme path is automatically added to the src path

blocks|key|5543070|text|我不认为你需要改变密码。在某些情况下，Global+settings可能会阻止您使用相应的主题徽标。因此，确保LOGO+IMAGE的全球设置和您的主题标志应该是相同的Drupal+8(一些情况)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|entityMap^0|J|F|1J|A^^$0|@$1|2|3|4|5|6|7|G|8|@$9|H|A|I|B|C]|$9|J|A|K|B|C]]|D|@]|E|$]]]|F|$]]

I don't think you need to change the code. In some cases, <code>Global settings</code> might be stopping you to take the respective theme logo. Hence, make sure <code>LOGO IMAGE</code> of Global Settings and your theme logo should be same in Drupal 8(Some cases).

blocks|key|3248229|text|一个简单的选项是将徽标放置在自定义块中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3248230|/admin/结构/块/块-内容|blockquote|3248231|这是灵活的，特别是有用的，如果你想要该标志显示不同的播种在网站的其他部分。|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|I|8|@]|9|@]|A|$]]|$1|E|3|F|5|6|7|J|8|@]|9|@]|A|$]]]|G|$]]

A simple option is to place the logo in a custom block.

<blockquote>
 /admin/structure/block/block-content
</blockquote>

this is flexible and particularely useful if u want that logo to show up sowehat different in other sections of the site

How can I set the logo in my custom theme in Drupal 8?

I can see that Drupal looks for the logo.svg file. I have a PNG logo.png file that I used in Drupal 7 and I would like to re-use it. I cannot set the logo as a theme setting as in Drupal 7.

Is there a way through UI or custom code in the theme to set the logo?

How do I set the theme logo?

如何在Drupal 8中的自定义主题中设置徽标？我可以看到Drupal查找logo.svg文件。我有一个PNG logo.png文件，我在Drupal 7中使用，我想重用它。我不能将徽标设置为主题设置，如Drupal 7中所示。在主题中是否有通过UI或自定义代码设置徽标的方法？
