一个PDF，两个PDF(PDFs)，100 个PDF —(PDFs—it)无论您有多少PDF文档，都可以在 macOS 上将它们全部组合成一个多页PDF。创建多页PDF不需要任何其他软件，因为您可以使用Preview应用程序将这些文档合并在一起。
还有其他编辑 PDF 的方法(other ways to edit a PDF)，但没有一种方法可以像预览(Preview)一样简单地创建合并的PDF文档。您还可以使用macOS 的自动化应用Automator一次合并大量PDF文档。让我们告诉您如何使用这两种方法在 macOS 上制作多页PDF 。
在预览中将 PDF 文档合并为多页 PDF(Merging PDF Documents Into a Multi-Page PDF in Preview)
Preview是一个核心的 macOS 应用，所以如果你有Mac，你不需要安装任何东西来使用它。您可以在Finder(Finder)的Applications文件夹中找到Preview或直接从Launchpad启动它。
- 首先，在预览(Preview)应用程序中打开您的第一个PDF文档。这是您要合并其他PDF文档的文档。在“预览(Preview)”窗口中找到该文档，然后单击“打开(Open)”按钮。
- 您应该能够在左侧菜单中查看每个页面的缩略图。如果没有，请单击View > Thumbnails。
- 使用左侧菜单，滚动查找插入其他PDF文档（或多个文档）的位置。单击(Click)页面缩略图以确保已选择该位置 - 插入的PDF(PDFs)将显示在其下方。选择正确的页面后，单击Edit > Insert > Page from File。
- 在出现的Finder窗口中，找到您的第二个文档，然后点按“打开(Open)”将其插入。
- 插入后，您插入的PDF中的页面将在左侧菜单中显示为缩略图。单击(Click) File > Save以保存合并的文档。
您可以重复此方法以合并两个以上的文档。您可以通过在左侧菜单中选择页面的缩略图来手动删除多余的文件，然后按键盘上的删除键(delete key)。
合并来自不同 PDF 文档的部分(Merging Sections From Separate PDF Documents)
用于创建多页PDF文档的File > Insert > Page from File 方法工作正常，但它会将文档合并为一个整体。要将一个PDF文档中的部分（例如 PDF 的第 4-8 页）(PDF)与另一个PDF合并，您需要在Preview中打开这两个文档。
- 从Finder的(Finder)Launchpad或Applications文件夹中打开Preview，然后打开您的第一个PDF文档。对第二个PDF(PDF)文档重复该步骤，并确保您可以在两个窗口中查看页面缩略图（View > Thumbnails）。
- 滚动找到您希望在第二个文档中复制的部分的开头。在按住Command 键(Command key)的同时，单击以在左侧菜单中选择要复制到第一个PDF文档的每一页。(PDF)
- 选择您的页面后，切换回包含您的第一个文档的预览(Preview)窗口，确保两个窗口都在视图中。在包含您的第一个PDF文档的(PDF)预览(Preview)窗口中，滚动到您希望插入新页面的位置。使用鼠标，将新页面拖到包含您的第一个PDF文档的(PDF)预览(Preview)窗口中，然后将它们放置到位。
您可以重复这些步骤以使用来自多个文档的页面创建多页PDF文档。完成后按File > Save以保存合并的PDF文档。
使用 Automator 合并多个 PDF 文档(Using Automator To Merge Several PDF Documents)
预览(Preview)非常适合合并PDF文档，但它可能是一个缓慢的过程。为了加快速度，您可以使用Automator应用程序同时使用多个其他PDF文档创建多页PDF。
(Automator)顾名思义，Automator是一款自动化应用程序。它是另一个核心 macOS 应用程序，因此它应该已经可供 macOS 用户在Finder的(Finder)Applications文件夹中使用，或者作为应用程序图标在Launchpad中使用。
- 首次启动Automator时，系统会询问您要创建哪种类型的文档。单击(Click) 应用程序(Application)，然后按选择(Choose)按钮进行确认。
- Automator窗口允许您选择要自动执行的操作。您会希望Automator首先找到您的PDF文件。在左侧的库(Library)菜单中，在文件和文件夹(Files & Folders )类别下，双击获取指定的查找器项目(Get Specified Finder Items)选项以将其添加到您的Automator工作流程中。
- 在右侧的工作流部分中，单击“获取指定的查找器项目(Get Specified Finder Items)”部分下的“添加(Add)”按钮。
- 使用出现的Finder窗口，找到要合并的PDF文件，然后按(PDF)添加(Add)按钮。此时，您可以添加任意数量的PDF文档。
- 您的 PDF 文件将出现在Automator工作流程的“(Automator)获取指定的查找器项目(Get Specified Finder Items)”部分中。在左侧库(Library )菜单的PDF(PDFs )部分下，双击合并 PDF( Combine PDFs )操作以将其添加到您的工作流程中。
- Automator 可以打乱您的PDF文档页面或按顺序添加它们，以便它们一个接一个地插入。确保在合并 PDF选项中选择了(Combine PDF )附加页面(Appending Pages)选项，以确保它们是按顺序添加的。
- 接下来，您需要为Automator设置保存新的多页PDF文档的位置。在左侧Library菜单中的Files & Folders下，双击Copy Finder Items选项将其添加到您的工作流程中。这将默认将您的新文件保存到桌面，但您可以通过单击(Desktop)Copy Finder Items工作流程选项中的下拉菜单来更改此设置。
- 双击Library > Files & Folders下的Rename Finder Options为新文档设置名称。从Rename Finder Items(Rename Finder Items)工作流程选项的下拉菜单中，选择Name Single Item。在名称(Name)选项框中为您的文档键入一个合适的名称。
- 准备好创建多页PDF文档后，请按右上角的“运行”按钮。(Run)
- Automator会警告您它不能将您的应用程序作为拖放操作运行。按OK忽略此警告。
Automator在您的新应用程序中执行完操作后，您合并的PDF(Automator)文档(PDF)将出现在您指定的位置。单击File > Save以保存您的Automator应用程序以供将来使用。
创建多页 PDF 文档的其他方法(Other Ways To Create Multi-Page PDF Documents)
Preview和Automator都提供了一种在 macOS 中合并PDF文档的简单方法，但如果您运行的是Windows，则可以在Photoshop中(Photoshop)创建多页 PDF(create multi-page PDFs)。对于Linux(Linux)等其他操作系统，请改用Google Docs等基于 Web 的服务来合并您的PDF文档。
您还可以使用预览在 Mac 上编辑 PDF(edit PDFs on Mac)，将新文本和图像添加到您的文档中。
Make Multi-Page PDF Files in Mac OS X
One PDF, two PDFѕ, 100 PDFs—it doesn’t matter how many РDF documents you have, it’s possible to combine them all into a multi-page PDF on macOS. Creating a multi-page РDF doesn’t require any additional software, as you can merge these documents together uѕing the Preview app.
There are other ways to edit a PDF, but none offer the simplicity of Preview for creating merged PDF documents. You can also use Automator, the automation app for macOS, to combine a large number of PDF documents at once. Let’s talk you through how to make a multi-page PDF on macOS using both methods.
Merging PDF Documents Into a Multi-Page PDF in Preview
Preview is a core macOS app, so if you have a Mac, you don’t need to install anything to use it. You can find Preview in the Applications folder in Finder or launch it directly from Launchpad.
- To start, open your first PDF document in the Preview app. This is the document you want to merge other PDF documents into. Locate the document in the Preview window, then click the Open button.
- You should be able to view thumbnails for each page in the left-hand menu. If you don’t, click View > Thumbnails.
- Using the left-hand menu, scroll to find the location to insert your other PDF document (or documents). Click on a page thumbnail to make sure the position is selected—the inserted PDFs will appear below it. Once you’ve selected the right page, click Edit > Insert > Page from File.
- In the Finder window that appears, locate your second document, then click Open to insert it.
- Once inserted, the pages from your inserted PDF will appear as thumbnails in the left-hand side menu. Click File > Save to save the merged document.
You can repeat this method to merge more than two documents. You can delete excess files manually by selecting the thumbnail for a page in the left-hand menu, then pressing the delete key on your keyboard.
Merging Sections From Separate PDF Documents
The File > Insert > Page from File method for creating multi-page PDF documents works fine, but it will merge documents as a whole. To merge a section from one PDF document (for instance, pages 4-8 of a PDF) with another PDF, you’ll need to open both documents in Preview.
- Open Preview from the Launchpad or Applications folder in Finder, then open your first PDF document. Repeat the step for your second PDF document, and make sure you can view page thumbnails in both windows (View > Thumbnails).
- Scroll to find the start of the section you wish to copy in your second document. While holding the Command key, click to select each of the pages you wish to copy to your first PDF document in the left-hand menu.
- With your pages selected, switch back to the Preview window containing your first document, making sure both windows are in view. In the Preview window containing your first PDF document, scroll to the position where you wish to insert the new pages. Using your mouse, drag the new pages to the Preview window containing your first PDF document, then drop them into place.
You can repeat these steps to create a multi-page PDF document using pages from multiple documents. Press File > Save to save the merge PDF document once you’ve finished.
Using Automator To Merge Several PDF Documents
Preview is great for merging PDF documents, but it can be a slow process. To speed things up, you can use the Automator app to create a multi-page PDF using several other PDF documents at the same time.
Automator is, as the name suggests, an automation app. It’s another core macOS app, so it should already be available for macOS users in the Applications folder in Finder, or as an app icon in Launchpad.
- When you first launch Automator, you’ll be asked what type of document you want to create. Click Application, then press the Choose button to confirm.
- The Automator window allows you to select the actions you’re looking to automate. You’ll want Automator to locate your PDF files first. In the left-hand Library menu, under the Files & Folders category, double-click the Get Specified Finder Items option to add it to your Automator workflow.
- In the workflow section on the right, click the Add button under the Get Specified Finder Items section.
- Using the Finder window that appears, locate the PDF files you wish to merge, then press the Add button. You can add as many PDF documents as you like at this point.
- Your PDF files will appear in the Get Specified Finder Items section in the Automator workflow. In the left-hand Library menu, under the PDFs section, double-click on the Combine PDFs action to add it to your workflow.
- Automator can either shuffle your PDF document pages or add them sequentially so they’re inserted one after another. Make sure that the Appending Pages option is selected in the Combine PDF options to make sure they’re added sequentially.
- You’ll want to set the location for Automator to save your new multi-page PDF document next. In the left-hand Library menu, under Files & Folders, double-click the Copy Finder Items option to add it to your workflow. This will default to saving your new file to the Desktop, but you can change this by clicking the drop-down menu in the Copy Finder Items workflow options.
- Set a name for your new document by double-clicking Rename Finder Options under Library > Files & Folders. From the drop-down menu in the Rename Finder Items workflow options, select Name Single Item. Type a suitable name for your document in the Name options box.
- Once you’re ready to create your multi-page PDF document, press the Run button in the top-right corner.
- Automator will warn you that it can’t run your application as a drag-and-drop operation. Press OK to ignore this warning.
Once Automator has run through the actions in your new application, your merged PDF document will appear in the location you specified. Click File > Save to save your Automator application for future use.
Other Ways To Create Multi-Page PDF Documents
Preview and Automator both offer a simple way to merge PDF documents in macOS, but if you’re running Windows, you can create multi-page PDFs in Photoshop. For other operating systems like Linux, use a web-based service like Google Docs to merge your PDF documents instead.
You can also use Preview to edit PDFs on Mac, adding new text and images to your documents.
