Like blog posts, a Page can have an “Excerpt” field to override the automatic excerpt of 55 words from the beginning of the content. However, many themes don’t display this field when editing pages, so you can’t edit it.
This extremely simple plugin forces page excerpt capability “on”. The Page excerpt is visible in internal search results and “Query Loop” blocks, as well as in the output of many plugins (e.g. CC Child Pages). So I generally do want to decide for myself whether to accept the default excerpt.

This plugin adds several improvements to WordPress’ default way of creating excerpts.
<ol>
<li>Keeps HTML markup in the excerpt (and you get to choose which tags are included)</li>
<li>Trims the excerpt to a given length using either character count or word count</li>
<li>Only the ‘real’ text is counted (HTML is ignored but kept)</li>
<li>Customizes the excerpt length and the ellipsis character that are used</li>
<li>Completes the last word or sentence in an excerpt (no weird cuts)</li>
<li>Adds a read-more link to the text</li>
<li>Ignores custom excerpts and use the generated one instead</li>
<li>Theme developers can use <code>the_advanced_excerpt()</code> for even more control (see the FAQ)</li>
</ol>
Most of the above features are optional and/or can be customized by the user or theme developer.
