How to convert HEIC photos to PDF

What HEIC is and why some sites reject it
HEIC (also called HEIF) is the photo format iPhones and iPads use by default. It takes less space than JPEG at the same quality, according to Apple’s support page on HEIF. Many websites and Windows apps still expect JPG, so an iPhone photo can be refused by an upload form or by tools that only read JPG, PNG and WebP, including our Images to PDF.
Scan to PDF and Resize photo in KB read HEIC directly. They download a decoder, about 3 MB, the first time you add a HEIC file, and the browser keeps it for later visits.
Convert HEIC to PDF, step by step
- Open Scan to PDF on your phone or computer.
- Select Choose photos and pick one or more HEIC files. On Windows or Mac, you can drag them onto the page.
- If the photo isn’t a sheet of paper, untick Find page edges automatically, so the whole photo is kept.
- Set Enhance to Original photo, so the colors aren’t changed.
- Set Page size to Fit image, so each page has the shape of the photo. A4 and US Letter place the photo on a standard page instead.
- Select Create PDF →, then Download result ↓.
You can add several photos at once. Each one becomes a page, in the order shown, and the arrows change the order.

When the photo is a document
If the HEIC photo shows a form or a letter, keep Find page edges automatically ticked and choose Black and white · sharp text, smallest file or Enhanced color. The tool crops to the paper and makes the text easier to read. How to make a PDF from photos on your phone covers this in more detail.
Other ways to avoid HEIC
- Take new photos as JPG. On iPhone, open Settings, tap Camera, then Formats, and choose Most Compatible. New photos are then saved as JPEG (Apple’s instructions). Photos you already took stay HEIC.
- Let the phone convert while sharing. Apple notes that photos shared by Mail, Messages or AirDrop may be converted to JPEG when the receiving device needs it. This depends on the app, so check the file name ending.
- On a Mac, open the photo in Preview, choose File, then Export, and pick JPEG or PDF.
If it doesn’t work
- The photo stays on “Adding the photo…” for a while. The decoder is downloading. Wait a few seconds on a slow connection.
- It fails offline. The decoder is saved only after its first use. Add one HEIC photo while online, and it works offline afterwards.
- The PDF is too large. Pick a Target size before creating it, or run the result through Compress PDF.
The HEIC files are decoded in your browser. You can check that no photo is sent with the Prove it’s private panel under the tool.
