文本荧光笔在^{(Text Highlighter)}Microsoft Edge中不起作用

Microsoft Edge可让您使用 4 种颜色突出显示PDF 。如果您的Microsoft Edge无法在Windows 10中突出显示^{(Windows 10)}PDF文档中的文本，那么其中一些建议肯定会对您有所帮助：

1. 将Microsoft Edge^{(Microsoft Edge)}浏览器更新到最新版本。
2. ^(Remove)从PDF中^(PDF)删除修改限制。
3. 检查是否扫描了 PDF。
4. 重置 Microsoft Edge^{(Reset Microsoft Edge)}浏览器设置。

让我们从这些选项开始。

1]将Microsoft Edge浏览器更新^{(Update Microsoft Edge Browser)}到最新版本

您使用的旧版本可能会导致Microsoft Edge荧光笔无法正常工作的问题。如果是这样，只需将浏览器更新到最新版本。

为此，请使用快捷键“Alt+F”打开Edge浏览器的“^(Edge)设置和更多菜单^{(Settings and more menu)}” 。或者，您可以单击右上角的三个水平点^{(three horizontal dots)}来打开此菜单。在该菜单中，单击“设置”^(Settings)选项。

在设置页面上，选择关于 Microsoft Edge^{(About Microsoft Edge)}选项。

现在，它将开始检查更新^{(checking for updates)}。如果有可用更新，它将自动开始更新Microsoft Edge。等待^(Wait)几秒钟。

更新完成后，使用重新启动^(Restart)按钮。

重新启动浏览器后，打开一个PDF文件，并尝试突出显示它。这应该可以解决问题。如果没有，您可以尝试其他选项。

2]重置Microsoft Edge浏览器设置^{(Reset Microsoft Edge Browser Settings)}

有时，重置浏览器设置^{(resetting the browser settings)}也可以解决此问题。此选项不会清除您保存的密码、历史记录和书签（或收藏夹）。不过，在使用此选项之前您必须小心，因为它会重置默认搜索引擎、起始页、固定选项卡、新选项卡页、清除 Microsoft Edge 的 cookie^{(clear cookies of Microsoft Edge)}等。

要重置Microsoft Edge的设置，请使用^{(Microsoft Edge)}设置和更多^{(Settings and more )}菜单（Alt+F快捷键）打开设置^(Settings)页面，然后选择设置^(Settings)选项。

在Edge浏览器的^(Edge)设置^(Settings)页面中，使用重置设置^{(Reset settings)}选项。

单击将设置恢复为默认值^{(Restore settings to their default values)}，将打开重置设置^{(Reset Settings)}弹出窗口。按重置^(Reset)按钮。

现在重新启动Microsoft Edge，添加PDF文件，并检查是否可以突出显示PDF。这应该可以解决问题。

3]从PDF文件中^{(PDF File)}删除修改限制^{(Remove Modification Restrictions)}

您要突出显示的PDF文件可能具有修改限制或权限。在这种情况下，您的PDF文件将变为只读。您无法对该PDF进行任何更改。你当然可以在PDF中选择文本，但是当内容修改受到限制时， ^(PDF)Microsoft Edge的高亮功能将不起作用。

如果是这种情况，那么您需要从该PDF中删除修改权限。有一些免费服务和软件可帮助您从PDF文档中删除此类权限/限制。

删除内容修改权限后，您可以使用Microsoft Edge浏览器突出显示PDF 。

4]检查PDF是否被扫描

扫描的PDF包含作为图像的页面。当存在扫描的PDF时，无法复制或突出​​显示该PDF中可用的文本内容。在这种情况下，您需要将扫描的 PDF 转换为可搜索的 PDF^{(convert that scanned PDF to searchable PDF)}。同样^(Again)，存在一些可以帮助您将扫描的PDF转换为普通PDF的服务和软件。

当PDF转换为可搜索的PDF时，您将能够在Microsoft Edge浏览器上突出显示它。

这些是您可以尝试摆脱Microsoft Edge突出显示功能不起作用的问题的一些选项。希望^(Hope)有帮助。

Text Highlighter not working in Microsoft Edge

Microsoft Edge brings a PDF highlighter feature that helps to highlight PDF text with any of the four colors: Light Blue, Green, Yellow, and Pink. You can simply select text in PDF file and use the right-click context menu to highlight that text. Though the feature works well, sometimes you may face an issue when you’re not able to highlight PDF in Microsoft Edge browser.

Text Highlighter not working in Microsoft Edge

Microsoft Edge lets you highlight PDF with 4 colors. If your Microsoft Edge can’t highlight text in PDF documents in Windows 10, then some of these suggestions are sure to help you:

1. Update the Microsoft Edge browser to the latest version.
2. Remove modification restrictions from PDF.
3. Check if PDF is scanned.
4. Reset Microsoft Edge browser settings.

Let’s start with these options one by one.

1] Update Microsoft Edge Browser to the latest version

It may happen that you are using an older version which is causing the issue that Microsoft Edge highlighter is not working. If so, simply update the browser to the latest version.

For this, open ‘Settings and more menu‘ of Edge browser using the shortcut ‘Alt+F’. Alternatively, you can click those three horizontal dots on the top right corner to open this menu. In that menu, click the Settings option.

On the Settings page, select About Microsoft Edge option.

Now, it will start checking for updates. If updates are available, it will automatically start updating Microsoft Edge. Wait for a few seconds.

When the update is completed, use the Restart button.

When the browser is restarted, open a PDF file, and try to highlight it. This should fix the issue. If not, you can try other options.

2] Reset Microsoft Edge Browser Settings

Sometimes, resetting the browser settings can also solve this problem. This option doesn’t clear your saved passwords, history, and bookmarks (or favorites). Still, you must be careful before using this option as it will reset the default search engine, start page, pinned tabs, new tab page, clear cookies of Microsoft Edge, etc.

To reset settings of Microsoft Edge, open Settings page using Settings and more menu (Alt+F shortcut), and select Settings option.

In the Settings page of Edge browser, use the Reset settings option.

Click on Restore settings to their default values and Reset Settings pop-up will open. Press the Reset button.

Now restart Microsoft Edge, add PDF file, and check if you can highlight PDF. This should fix the problem.

3] Remove Modification Restrictions from PDF File

It is possible that the PDF file you want to highlight has modification restrictions or permissions. In that case, your PDF file becomes Read-only. You can’t make any changes to that PDF. You can definitely select text in PDF, but the highlight feature of Microsoft Edge won’t work when the content modification is restricted.

If this is the case, then you need to remove modification permissions from that PDF. There are some free services and software available to help you remove such permissions/restrictions from a PDF document.

Once the content modification permissions are removed, you can highlight PDF using the Microsoft Edge browser.

4] Check if PDF is scanned

A scanned PDF contains pages as images. When there is a scanned PDF, the text content available in that PDF can’t be copied or highlighted. In this case, you need to convert that scanned PDF to searchable PDF. Again, there exist some services and software that can help you convert scanned PDF to normal PDF.

When the PDF is converted to searchable PDF, you will be able to highlight it on the Microsoft Edge browser.

These are some options you can try to get rid of the issue that Microsoft Edge highlighting feature is not working. Hope something helps.
