图像可以独立存在。但有时，您需要将多个图像组合成一个PDF文件并保存或共享。例如，您可以在课堂上拍摄白板的照片，并使用以下工具之一将这些多张图像转换为一个PDF文件。
PDF文件很常见，您可以在任何平台上使用它们。这就是为什么知道如何快速将JPEG或PNG图像转换为PDF会派上用场的原因。让我们探索一些从多个图像 创建PDF文件的最简单方法。(PDF)
在 Windows 中使用 PDF 打印机
Microsoft Print to PDF是Windows中的本机工具。它是可从所有具有打印(Print)功能的应用程序访问的虚拟打印机。让我们在图像文件夹上尝试一下。

您知道您甚至可以使用 Microsoft Word 对 PDF 文档进行密码保护(use Microsoft Word to password protect a PDF document)吗？
使用(Use)在线图像(Online)到PDF 转换器(PDF Converter)
PDF格式是一种通用格式，支持它的许多工具也是如此。您会在网上找到许多免费和付费的文件转换器(free and paid file converters online)，几乎所有的文件转换器都处理 PDF。
这里有三个可以通过单击将多个图像转换为PDF文件的方法。
JPG to PDF是一个不错的小型PDF转换工具，它不会对您施加水印(force a watermark)或任何其他限制。一批拖放(Drop)或(Drag)上传20 张图像。没有文件大小限制，因此您可以上传任意数量的图像。
它不会压缩(compress the images)您上传的图像。在转换文件之前，您可以使用编辑工具来旋转、优化或缩小图像。为每个图像单独下载 PDF文件，或单击“(Download PDF)组合(COMBINED)”按钮将它们全部放在一个PDF文档中。
我爱PDF(I Love PDF)
这是另一个简单的JPG到PDF实用程序，它为您提供了更多使用选项。您可以设置方向，使用三种典型的页面大小，并以边距完成。
将图像转换为PDF文件后，将其直接下载到桌面或保存在Google Drive或Dropbox文件夹中。通过您的云帐户与您的朋友共享文件或使用可共享链接。
服务器会在两小时后清除所有存储的文件。

PDF Candy是安全的，该网站称其服务器上没有存储任何文件。每个工具都是免费的，没有任何限制、限制或隐藏的障碍。您可以下载并离线使用 适用于Windows的PDF Candy软件。(PDF Candy)
注意：(Note:)令人惊讶的是，Adobe 的在线JPG 到 PDF 转换器(JPG to PDF converter)不允许您上传多张照片并将其转换为PDF。
使用 Chrome 扩展程序
有一些Chrome扩展程序也可以完成这项工作。Multiple Images to PDF是一个Chrome扩展程序，它在将(Chrome)PNG和JPG图像转换为(JPG)PDF之前不会通过服务器。
扩展是进行转换的网站的前端。正如您在上面的屏幕中看到的，您可以控制一些文件参数。例如，您可以重新缩放图像并减小PDF的文件大小。
每个文件的大小限制为 20MB。该在线工具可以处理JPEG、PNG、BMP、GIF和WEBP图像格式。
使用 Adobe Acrobat(Use Adobe Acrobat)创建可搜索的 PDF 文件(Create Searchable PDF Files)

Acrobat允许您在创建PDF之前更正和增强图像。您可以使用文本识别从图像文件和白板图像的扫描中 创建可搜索的PDF文件。(PDF)
但创建PDF是一个简单的三步过程：
- 选择创建 PDF(Create PDF)工具。
- 浏览(Browse)到文件的位置。

想一想使用PDF格式的图像的更多创造性用途，并在下面告诉我们。
How to Convert Multiple Images into PDF Files
Images can stand alone on their own. But sometimes, yoυ need to combine several images into a single PDF file and save it or share it. For instance, you can snap photos of a whiteboard in class and use one of the toоls below to convert these multiple imаges into one PDF file.
PDF files are common and you can use them on any platform. That’s why knowing how to convert JPEG or PNG images into a PDF quickly can come in handy. Let’s explore some of the easiest ways to create a PDF file from multiple images.
Use the PDF Printer in Windows
Microsoft Print to PDF is a native tool in Windows. It is a virtual printer accessible from all apps that have a Print function. Let’s try it out on an image folder.
- Place all your images in a folder and sort them in the sequence you want. Rename your files if necessary.
- Select all images and then go to the Share tab on the toolbar and click on Print.
- Select Microsoft Print to PDF from the list of available printers. Use the right and left arrow button to scroll through the images you selected.
- Choose Paper size and Quality. A4 is the default in most cases.
- Select from the pre-designed layouts on the right. For instance, you can opt for Full page photo if you need one. Printing the images as a Contact sheet is a good low-cost option if you have several images and you want to check their relative merits.
- Click the Options link in the lower-right corner of the dialog box for more options to configure the print. In this dialog box, you can sharpen the images for printing, if you want to print the PDF.
- Keep the Only show options that are compatible with my printer option selected if you are going to use your own printer.
- Click the Printer Properties link and choose between the Landscape or Portrait orientation.
- Click the OK button and return to the Print Pictures dialog box. Keep the Fit picture to frame checked. It’s always on by default.
- Click Print to create your PDF file, then save the PDF file on your desktop.
Use Microsoft Word
Conversion to PDF is part of Microsoft Office too and can help you export Office documents in the PDF format with a click. Microsoft Word can also help you layout your images in creative ways and then export it as a PDF file.
- Open Word and start a new Blank Document.
- Go to Ribbon > Insert > Insert Pictures From. Use the menu to insert pictures from your desktop or any other online source. Adjust the size of images by using the selection handles. You can use Word Tables and other formatting tools to arrange the pictures in a layout you want.
- Save the document. Then, go to File > Export > Create PDF/XPS Document to turn the file with multiple images into a PDF file.
Did you know that you can even use Microsoft Word to password protect a PDF document?
Use an Online Image to PDF Converter
The PDF format is a universal format and so are the many tools that support it. You will find many free and paid file converters online and almost all of them handle PDF.
Here are three that can convert multiple images to PDF files with a click.
JPG to PDF is a nice little PDF conversion tool that does not force a watermark or any other restriction on you. Drag and Drop or upload 20 images in one batch. There are no file limit sizes so you can upload as many images you want.
It does not compress the images you upload. Before you convert the files, you can use the editing tools to rotate, optimize, or scale down the images. Download PDF files individually for each image, or click the COMBINED button to get them all in a single PDF document.
This is another simple JPG to PDF utility that gives you a few more options to work with. You can set an orientation, use three typical page sizes, and finish it with a margin.
After you convert the images to a PDF file, download it straight to your desktop or keep it in a Google Drive or Dropbox folder. Share the file with your friends from your cloud accounts or use the shareable link.
The server erases all stored files after two hours.
Want a Swiss knife for all your PDF needs? PDF Candy has a bunch of tools to handle PDF files. The JPG to PDF is one of the options.
PDF Candy is secure, and the site says that no files are stored on their servers. Every tool is free and without any restrictions, limitations, or hidden obstacles. There’s a PDF Candy for Windows software you can download and use offline.
Note: Surprisingly, Adobe’s online JPG to PDF converter doesn’t allow you to upload more than one photo and convert it to a PDF.
Use a Chrome Extension
There are a few Chrome extensions that can also do the job. Multiple Images to PDF is a Chrome extension that does not go through a server with your PNG and JPG images before it converts them to PDF.
The extension is a frontend for the site which does the conversion. As you can see in the screen above, there are a few file parameters you can control. For instance, you can rescale the image and reduce the file size of the PDF.
There’s a 20MB size limit per file. The online tool can handle JPEG, PNG, BMP, GIF, and WEBP image formats.
Use Adobe Acrobat to Create Searchable PDF Files
If you have Adobe Acrobat DC installed on your computer, you’ve got a powerful option in your hands. Adobe Acrobat is a paid software and comes with other bells and whistles.
Acrobat allows you to correct and enhance images before you create the PDF. You can use text recognition to create searchable PDF files from scans of image files and whiteboard images.
But creating a PDF is a simple three step process:
- Select the Create PDF tool.
- Browse to the location of your file.
- Click Create.
Adobe Photoshop can also create multi-page PDF files in a jiffy, but you can set aside that solution for specialized jobs.
Put PDF Files With Multiple Images to Creative Uses
It’s no use converting multiple images into a PDF file. It will only add to the bloat. But what you can do is use this format for some creative uses.
- Turn your Instagram photos into PDF and print them.
- Scan all your instruction manuals and convert them into a single PDF.
- Thanks to OCR that can extract text from images, you can capture entire whiteboard images. The original images and the extracted notes can be useful as study materials.
Think of more creative uses of using images with the PDF format and let us know below.
