Sometimes a PDF is the wrong format. A form asks for a JPG, a chat app will not preview a PDF, or you only want one page as a picture to post. Finding out how to convert a PDF to JPG on an iPhone is harder than it should be, because iOS does not offer it as a plain menu item. These methods all work, and each suits a different need.
Method 1: a browser tool in Safari
This is the most flexible route, and it needs no app. DocPro's PDF to images runs inside Safari, draws each page on your phone and does not upload the file.
- Open PDF to images in Safari.
- Tap the drop area and choose the PDF from Files, iCloud Drive or another location.
- Under Format, pick JPEG. A quality slider appears, and 90 percent is the default.
- Choose a resolution: 72, 100, 150, 200 or 300 dpi. The tool shows the pixel size of page 1 so you can see what you will get.
- Pick the pages you want, or leave them all selected.
- If you chose several pages, decide between separate files in a ZIP or one tall image. Then tap Convert to images.
With a single page, you get one image and a preview. With several pages, the images download as a ZIP. The shorter task page PDF to JPG starts with JPEG already selected.
Opening the ZIP and saving to Photos
Safari saves downloads to the Files app. Open Files, go to Downloads and tap the ZIP once. iOS unpacks it into a folder next to it. Open the folder and you will see one image per page, named after your PDF with the page number added.
To put them in your photo library, open an image, tap the share button and choose Save Image. To save many together, tap Select, pick the images, then tap the share button and choose Save Images. They then appear in the Photos app like any other picture.
Method 2: take a screenshot
For one page and no extras, a screenshot is the fastest option. Open the PDF in Files or Safari, zoom so the page fills the screen, and press the side button and volume up button together. The screenshot lands in Photos.
The drawbacks are real. The image is only as sharp as your screen, there will be status bar and edges to crop, and a long page needs several screenshots. The default screenshot format on iPhone is often PNG or HEIC rather than JPG, so you may still need to convert it. Use this for a quick share, not for anything that will be printed or uploaded to a form.
Method 3: the Shortcuts app
The Shortcuts app can build a small automation that takes a PDF and returns images. It has actions for working with PDFs and for turning PDF pages into images, and you can add a Share Sheet trigger so the shortcut appears when you share a file. The action names and layout change between iOS versions, so search the action list for PDF and image when you build it, and test it on a short file first.
This route suits people who convert PDFs often and like a one-tap workflow. It takes some setup, and you control less over resolution than with a dedicated tool.
Method 4: Quick Look in Files
In the Files app, a long press on a PDF opens a menu with Quick Look, which shows the pages full screen. It is good for checking which page you want, and you can then take a screenshot of that page. Quick Look on its own does not export pages as pictures, so treat it as a viewer rather than a converter.
Which should you use?
- One page, quick share: screenshot.
- Pages for a form, print or upload: browser tool, with 150 to 300 dpi.
- Regular conversions: a Shortcut, if you are happy to set one up.
- Just checking pages: Quick Look.
Keeping the images a sensible size
A JPG from a PDF page at 300 dpi can be a few megabytes. If a form has a size limit, drop to 150 dpi or lower the quality slider. For images that must be under a size in KB, see Compress image to a target size. If you need the pictures back as a single PDF, Images to PDF puts them together again.
If the PDF itself is the problem, because it is too large to send, the guide on how to reduce PDF size on iPhone and Android covers that.
Privacy
PDFs on a phone are often IDs, tickets and statements. Converting in the browser tab means the file is not sent to a server. You can confirm it by turning on airplane mode after the page loads and running the conversion.
Frequently asked questions
Can an iPhone convert a PDF to JPG without an app?
Yes. A browser tool such as DocPro's PDF to images works in Safari, so nothing needs installing. You choose the file from the Files app, convert it and save the result.
Why did I get a ZIP file instead of pictures?
A PDF with several pages becomes several images, and they are bundled in a ZIP to download in one go. In the Files app, tap the ZIP to unpack it into a folder. With one page selected you get a single image.
How do I get the images into my Photos app?
Open the unpacked image in Files, tap the share button and choose Save Image. To save several at once, select them in Files, tap Share and choose Save Images.
What resolution should I pick?
150 dpi is a good default for reading on screen and sending. Use 200 or 300 dpi if you need to print or zoom in on small text. Higher settings make larger files.
