To convert a JPG to PDF, you don't need to download anything. Every major device already has a built-in "print to PDF" feature that turns an image into a PDF in a few clicks. Below are the exact steps for Windows, Mac, and iPhone, plus how to combine several JPEGs into a single PDF when you have more than one.
Quick note on this site: jpgtoolkit doesn't have a standalone JPG to PDF converter yet. What it does have is a merge tool that stitches multiple JPGs into one PDF, which is the more common need anyway. We'll cover that at the end.
How to save a JPG as a PDF on Windows
Windows has a virtual printer called Microsoft Print to PDF that's built in. Using it is the simplest way.
- Find your JPG in File Explorer and double-click to open it in the Photos app.
- Click the print icon at the top (or press Ctrl + P).
- In the printer dropdown, choose Microsoft Print to PDF.
- Check the orientation and size, then click Print.
- A save dialog opens. Name the file, pick a folder, and click Save.
That's it. You now have a PDF of your image. This works from almost any app that can print, not just Photos.
How to convert a JPG to PDF on Mac
Mac gives you two easy routes through Preview, which is already installed.
Option 1: Export as PDF
- Open the JPG in Preview (double-click it, or right-click and choose Open With > Preview).
- Go to File > Export as PDF in the menu bar.
- Choose a name and location, then click Save.
Option 2: Print to PDF
- With the image open in Preview, choose File > Print (or press Command + P).
- In the print window, click the PDF dropdown in the bottom-left corner.
- Select Save as PDF, name the file, and save.
Both give you the same result. Export as PDF is a touch faster; Print is handy if you want to set paper size or margins first.
How to convert a photo to PDF on iPhone
Your iPhone can do this with no app to install. There's a hidden trick in the Print screen.
- Open the Photos app and select the picture you want.
- Tap the share icon (the square with an arrow) in the bottom-left corner.
- Scroll down and tap Print.
- On the print preview, pinch outward (spread two fingers) on the image thumbnail. This opens it as a full PDF.
- Tap the share icon again in the top-right corner, then save it to Files, mail it, or send it wherever you need.
The pinch-to-open-PDF gesture is easy to miss, but it's the key step. Once you know it, converting any photo to PDF on iPhone takes seconds.
How to combine several JPEGs into one PDF
Often the real goal isn't a single image, it's turning a stack of photos, receipts, or scanned pages into one tidy PDF. Here are your options.
On Windows: In File Explorer, select all the JPGs you want (hold Ctrl and click each, or drag a box around them). Right-click and choose Print. In the print dialog, set the printer to Microsoft Print to PDF and click Print. Windows lays each image on its own page and saves them as one PDF.
On Mac: Open the first image in Preview, then drag the rest into the thumbnail sidebar to add them as extra pages. Arrange them in the order you want, then use File > Export as PDF to save the whole set as a single document.
The easiest cross-device way: Use our merge JPG tool. Add your images, drag them into the order you want, and export them as one combined PDF. It runs in your browser, so your files stay on your device, and it works the same whether you're on Windows, Mac, a Chromebook, or a phone. That's the option we'd point you to for combining images, since it gives you control over page order without fiddling with print menus.
A few things worth knowing
Wrapping a JPG in a PDF doesn't usually hurt quality. The PDF just holds your existing image, so what you put in is what you get out. If a file looks worse afterward, the tool probably re-compressed it; the built-in methods above generally don't.
