The simplest way to make a PDF with images
The fastest route depends on what you already have. If you are working on a Windows computer, you can insert images into a Word document, then save it as a PDF without installing anything new — Word has this built in. On a Mac, you can do the same with Pages. If you are starting from loose image files and want to combine them into one PDF, your computer's native tools (Preview on Mac, Photos or File Explorer on Windows) can do this without extra software.
The reason to know your starting point is that each path takes a different number of steps. Combining existing images is usually faster than creating a document first. Arranging images in a specific order takes longer than just converting what you already have. Knowing where you are starting saves you from opening the wrong tool and wasting time.
Key Takeaways
- Windows users can insert images into Word and save as PDF; Mac users can do the same with Pages, and both are free if you already own the software.
- If you have loose image files, Preview on Mac or Photos on Windows can combine them into a single PDF without opening a document editor.
- The order matters — arrange images before converting, because rearranging them after the PDF is created requires a different tool.
- Image size and quality affect file size; compressing large photos before combining them keeps the final PDF smaller and faster to share.
Creating a PDF from images in Word (Windows)
Open Word and create a blank document. Go to the Insert tab at the top, then click Pictures. Choose "This Device" to browse your computer for image files. Select the first image you want to include and click Insert. The image will appear in your document.
Repeat this step for each image you want to add. As you insert them, they will stack vertically down the page. If an image is too large or too small, click it once to select it, then drag the corner handles to resize. You can also right-click the image and choose "Wrap Text" to change how text flows around it — for a PDF that is only images, this does not matter much, but it gives you control if you want to add captions or labels.
Once all images are in the document in the order you want, go to File, then Save As. In the dialog that opens, change the file type from "Word Document" to "PDF". Give your file a name and choose where to save it, then click Save. Word will convert the document to PDF automatically.
Creating a PDF from images in Pages (Mac)
Open Pages and create a blank document. Go to Insert at the top menu, then Image, then choose "Choose". Browse your computer for the first image and click Insert. The image will appear in your document.
Add more images the same way, one at a time. Pages will arrange them as you insert them. Click any image to select it and resize by dragging the corners. If you want to rearrange the order, click and drag an image to a new position in the document.
When all images are in place, go to File, then Export To, then PDF. A dialog will open with options for quality and page size. The default settings work for most purposes. Choose where to save the file and click Next, then Save.
Combining loose image files into a PDF on Mac
If you have multiple image files sitting in a folder and want to turn them into a single PDF without opening a document editor, Preview can do this in a few steps. Open Finder and navigate to the folder holding your images. Select the first image and open it with Preview (right-click, Open With, Preview).
Once Preview is open with the first image, go to File at the top menu, then Open. Browse to your folder and hold down Command while clicking each additional image you want to include. This selects multiple files. Click Open, and Preview will add them all to the same window as separate pages.
The images will appear in the order you selected them. If you need to rearrange them, go to View at the top menu and click Thumbnails. A sidebar will appear on the left showing each image as a small preview. Click and drag these thumbnails to reorder them. When the order is correct, go to File, then Export As, and choose PDF from the Format dropdown. Name your file and click Save.
Combining loose image files into a PDF on Windows
Windows does not have a built-in tool quite as straightforward as Mac's Preview, but you can use the Photos app if your images are already there, or you can use File Explorer with a free online converter as a backup. To use Photos, open the app and navigate to the folder containing your images. Click the first image to open it, then hold Ctrl and click each additional image you want to include to select multiple files.
Once you have selected all the images, right-click and look for an option to print or export. If you see "Print", click it, then in the print dialog look for "Print to File" or "Microsoft Print to PDF" as the printer. This will save the images as a PDF. If Photos does not offer this option on your version of Windows, the fastest alternative is to insert the images into a Word document and save as PDF, which is described above.
Reducing file size before combining images
Large image files create large PDFs, which are slower to email and harder to store. Before you combine images, consider compressing them. On a Mac, you can do this in Preview: open an image, go to Tools, then Adjust Size. Reduce the width or height (the other will adjust automatically to keep the image proportional), then save. On Windows, right-click an image file, choose Send To, then Compressed (Zipped) Folder. This creates a smaller version you can then use.
Another option is to use an online image compressor — search for "image compressor" and you will find several free tools that let you upload an image and read a smaller version. Compress your images before inserting them into your document or combining them with Preview or Photos. This step takes a few extra minutes but can cut your final PDF size in half.
Arranging and editing images after the PDF is created
If you have already created a PDF and realize the images are in the wrong order or you want to remove one, you have two options. The simplest is to go back to your original document (Word, Pages, or your image folder) and redo the steps above — this is faster than trying to edit the PDF itself. The second option is to use a PDF editor, but most of these are paid software or require a subscription.
If you must edit the PDF itself, some free online tools let you upload a PDF, rearrange pages, delete pages, or rotate them. Search for "free PDF editor" to find options. Keep in mind that uploading a file to an online tool means sending it to someone else's server, so do not use this method for documents that contain private information.
Frequently Asked Questions
Can I add text or captions to images before converting to PDF?
Yes. If you are using Word or Pages, you can type text directly into the document alongside or below each image. If you are combining images with Preview or Photos, you would need to add text in a document editor first, or use a PDF editor afterward — but this is slower than adding text before converting.
What image file types work for creating PDFs?
JPG, PNG, and GIF files all work in Word, Pages, Preview, and Photos. TIFF and BMP files usually work too, though less commonly. If you have an unusual file type and the tool will not open it, you can convert the image using a free online converter first.
Why is my PDF much larger than I expected?
Large image files create large PDFs. If your images are high-resolution photos, compress them before combining them. Also check that you are not accidentally inserting the same image twice or including images you do not need.
Can I create a PDF with images on my phone or tablet?
Yes, but the process is different. On an iPhone or iPad, you can use the Notes app to add images, then export as PDF. On Android, Google Drive lets you upload images and export them as a PDF. Both methods are slower than using a computer, so use them only if you do not have access to a desktop or laptop.
What if I want the images to be side-by-side instead of stacked vertically?
In Word or Pages, click an image and go to the text wrapping options (right-click and look for "Wrap Text" or similar). Change the setting so text wraps around the image, then drag the image to position it next to another image. This takes practice and can be finicky, so it is usually easier to resize images smaller and let them sit next to each other naturally as you insert them.
