HEIC to PDF: How to Convert iPhone Photos on Any Device
By the PNG to PDF team ·
To convert HEIC to PDF, use a tool that reads HEIC directly, or change how the iPhone saves photos so the files arrive as JPEG. HEIC is the format iPhones use in High Efficiency mode, and some PDF tools and Windows apps cannot open it without help. The routes below start with the least effort.
Why HEIC to PDF fails in some tools
HEIC is Apple’s name for the HEIF photo format. Apple says HEIF photos use less space than JPEG without a visible loss in quality, and the camera setting lives in Settings > Camera > Formats: Most Compatible records JPEG, and High Efficiency records HEIF. Windows Photos needs two Microsoft Store packages to open HEIC, HEIF Image Extensions and HEVC Video Extensions, and Microsoft says you need both. A converter that cannot read HEIC reports an unsupported file, so the fix is either on the tool side or on the file side.
HEIC to PDF routes by device
| Where you are | Route | Note |
|---|---|---|
| iPhone, new photos | Settings > Camera > Formats > Most Compatible | New photos are saved as JPEG; existing ones stay HEIC |
| iPhone, existing photos | Preview app: Actions Menu > Export | Apple’s iPhone guide lists HEIC, JPEG, PDF, PNG and TIFF as export formats |
| Mac | Preview: File > Export, then pick a type in the Format menu | Apple’s page does not list the formats, so check that PDF appears |
| Mac, several files | Finder: select files, Control-click, Quick Actions > Create PDF | Pages follow your selection order; Apple does not list supported file types, so test one HEIC file |
| Windows | Install the two Microsoft packages, open the photo in Photos, print to Microsoft Print to PDF | The print step is described in a Microsoft Q&A answer from a community moderator |
| Chrome on a computer | An extension that accepts HEIC, such as PNG to PDF | Its store listing names HEIC, including iPhone photos; files are processed inside the extension on your computer; the site publishes no limits |
Microsoft’s page also lists ways to avoid the packages: many devices convert HEIC photos automatically when you transfer them to a PC, emailing them to yourself works, and OneDrive converts photos on upload. Apple adds that sharing by AirDrop, Messages or email to a device that does not support HEIF can send JPEG instead.
Check the result and pick the next step
Open the PDF and confirm that every photo is the right way up and sharp at 100% zoom. Phone photos carry rotation data that some tools ignore; photo to PDF shows a test of that. For a whole camera roll, convert photos to PDF in bulk covers one file versus many, and turn photo to PDF helps you pick the fastest method for a single photo. If you also have PNG or WebP files, image to PDF lists how each format is handled.
FAQ
Can I convert HEIC to PDF without installing anything?
On an iPhone or Mac, yes, with Preview or Finder. On Windows you need the two Microsoft packages, or an alternative such as a browser extension that reads HEIC.
Why does my iPhone photo not open on Windows?
Windows needs HEIF Image Extensions and HEVC Video Extensions from the Microsoft Store to open HEIC photos in Photos, per Microsoft.
Do I lose quality when I convert HEIC to PDF?
It depends on the tool. Converting through JPG adds a lossy step, and a tool that reads HEIC directly avoids it. Compare the PDF with the photo at 100% zoom.
