Python approach working for me, except you have to specify the zoom level:

<pre><code>driver.execute_script("document.body.style.zoom='zoom %'")
</code></pre>

Have 'zoom%' = whatever zoom level you want. (e.g. '67%'). This works for Chromedriver, which doesn't seem to accept the send_keys commands.

blocks|key|154104|text|我知道这已经很晚了，但是如果你不想使用动作类(或者像我一样遇到任何错误)，你可以使用纯JavaScript来实现。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|154105|以下是代码|154106|​|154107|((IJavaScriptExecutor)+Browser.Driver).ExecuteScript("document.body.style.zoom+=+'70%25';");|code-block|syntax|javascript|154108|154109|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|P|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|Q|8|@]|9|@]|A|$I|J]]|$1|K|3|E|5|6|7|R|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|M|$]]

I know this is late, but in case if you don't want to use action class (or getting any errors, as I did) you can use pure JavaScript to do so.

Here is the code

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>((IJavaScriptExecutor) Browser.Driver).ExecuteScript("document.body.style.zoom = '70%';");</code></pre>
</div>
</div>

blocks|key|154147|text|对于放大到30%25(或您希望的任何其他值，但在我的例子中为30%25)使用|type|unstyled|depth|inlineStyleRanges|entityRanges|data|154148|JavascriptExecutor+jse+=+(JavascriptExecutor)driver;
jse.executeScript("document.body.style.zoom+=+'30%25';");|code-block|syntax|javascript|154149|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

For Zoom In to 30%(or any other value you wish but in my case 30%) use

<pre><code>JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.body.style.zoom = '30%';");
</code></pre>

blocks|key|154161|text|使用Robot类对我很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|154162|for(int+i=0;+i<3;+i%2B%2B){

Using Robot class worked for me:

<pre><code>for(int i=0; i&lt;3; i++){
 Robot robot = new Robot();
 robot.keyPress(KeyEvent.VK_CONTROL);
 robot.keyPress(KeyEvent.VK_MINUS);
 robot.keyRelease(KeyEvent.VK_CONTROL);
 robot.keyRelease(KeyEvent.VK_MINUS);
 }
</code></pre>

this will zoom out 3 times.

you may use "Keys.chord" method for Zoom out and Zoom in

Zoom OUT

<pre><code> WebElement zoomPage = driver.findElement(By.tagName("html"));
 zoomPage.sendKeys(Keys.chord(Keys.CONTROL, Keys.ADD))
</code></pre>

when you are done with your work and want to reset browser back to 100% then use below code
If you want to click on any element, so before click event you may reset you browser window to 100 % after you may click on it.

<pre><code> zoomPage.sendKeys(Keys.chord(Keys.CONTROL, "0"));
</code></pre>

You may user Java script code as well for Zoom OUT

<pre><code> JavascriptExecutor executor = (JavascriptExecutor)driver;
 executor.executeScript("document.body.style.zoom = '110%'");
</code></pre>

How to change page zoom level in Selenium WebDriver?
I tried: 

<pre><code>driver.Keyboard().pressKey(Keys.Control);
driver.Keyboard().pressKey(Keys.Add);
</code></pre>

But it doesn't work.

Selenium WebDriver zoom in/out page content

Python

Java

如何在Selenium WebDriver中更改页面缩放级别？我试过了：driver.Keyboard().pressKey(Keys.Control);driver.Keyboard().pressKey(Keys.Add);但它不起作用。
