Can I drag HEIC files directly into the JPG-to-PDF tool?

No. The tool accepts .jpg, .jpeg, and .png files, not HEIC. You must convert HEIC to JPEG first using Preview, Photos, or Quick Actions.

Will converting HEIC to JPEG reduce the photo quality?

The conversion uses the image data as is. JPEG uses lossy compression, but at typical quality settings the visible difference is minimal for most uses.

Do I need to install any software on my Mac to do this?

No. Preview, Photos, and Quick Actions are built into macOS. The PDF tool at pdf-converter-mac.net runs in a browser. No additional apps are required.

What if I have an older version of macOS that does not have Quick Actions?

Quick Actions require macOS Monterey 12 or later. On older versions, use the Photos app to export HEIC files as JPEG in bulk, or use Preview for individual files.

Turn iPhone HEIC Photos Into a PDF on Your Mac

If your iPhone saves photos as HEIC files and you need a PDF, you can handle the whole job on your Mac without extra software. Because most PDF tools accept JPEG or PNG but not HEIC, the workflow has two steps. First, turn your HEIC photos into JPEGs using apps already on your Mac. Second, combine those JPEGs into a PDF. Preview, the Photos app, and Finder Quick Actions each handle one part of the chain.

Why HEIC Appears on Your Mac

iPhones set to High Efficiency save photos as HEIC. This format uses less storage than older formats but is not as widely supported. To move from HEIC to a PDF on a Mac, you must first change the HEIC file into a format that PDF tools accept. The most compatible camera format for sharing and printing is still JPEG. Mac apps like Preview and Photos can export HEIC images as JPEG without losing visible quality.

Change Your IPhone Camera Settings to Avoid HEIC

If you take new photos often, you can stop HEIC files from arriving on your Mac. On the iPhone, open Settings, then Camera, then Formats, and choose Most Compatible. This setting saves new photos as JPEG. Photos already on your phone will remain HEIC, but future images will be JPEG. That simplifies any iPhone-photos-to-PDF task because you skip the conversion step.

Export a Single HEIC as JPEG Using Preview

Preview can open a single HEIC image and export it as a JPEG. This method works well for a few photos.

Steps for One HEIC File

Open the HEIC file in Preview (double-click the file).
Go to the File menu and choose Export.
In the Export window, set Format to JPEG.
Adjust quality or size if you like (the default is fine for most uses).
Click Save. The new JPEG file appears in your chosen folder.

Repeat for each HEIC photo you need. If you have many images, the Photos app or Quick Actions will be faster.

Export HEIC to JPEG in Bulk Using the Photos App

The Photos app can export several HEIC images at once as JPEGs. This is the best method when you have a folder of iPhone photos to turn into a PDF.

Steps for Multiple HEIC Files

Open the Photos app.
Select all the HEIC photos you want to export. Hold Command and click each one, or drag to select a group.
Go to the File menu and choose Export, then Export [n] Photos.
In the dialog that appears, set Photo Kind to JPEG.
Choose a destination folder and click Export.

The Photos app turns every selected HEIC into JPEG and places the copies in the folder you picked. This bulk export gets you to a PDF on a Mac without opening each file individually.

Use Finder Quick Actions to Turn HEIC Into JPEG

If your Mac runs macOS Monterey 12 or later, you can change HEIC files directly from Finder. Quick Actions include a Convert Image option that outputs JPEG.

Steps Using Quick Actions

In Finder, select one or more HEIC files.
Right-click (or Control-click) the selection.
From the menu, choose Quick Actions, then Convert Image.
The new JPEG files appear in the same folder, named with a JPEG extension.

This method is fast and does not require opening any app. It works for single files or groups, making it a good choice if you already have the files in a folder and want a quick HEIC-to-JPEG change.

Build the PDF from Your JPEG Files

After you have JPEG versions of your HEIC photos, you can combine them into a PDF. The site pdf-converter-mac.net offers an online tool that accepts .jpg, .jpeg, and .png files. It does not accept HEIC. You upload your JPEG images, and the tool embeds each image at quality 90 into a PDF. The process is straightforward and does not require an app or leave a watermark.

How to Assemble the PDF

Gather all the JPEG files you created in the previous steps.
Go to pdf-converter-mac.net and select the JPG to PDF option.
Upload your JPEG images. The tool arranges them in the order you select.
Download the resulting PDF.

This final step completes the HEIC-to-PDF-on-Mac workflow. By turning HEIC into JPEG first, you can use any standard JPG-to-PDF tool.

Tips for a Smooth Workflow

These practices help avoid problems when turning iPhone photos into a PDF on your Mac.

Keep Originals Safe

The methods above create copies. Your original HEIC files remain unchanged.

Control File Order

After export, rename JPEG files if you want a specific order in the PDF.

Handle Large Batches Fast

Use the Photos app for big exports. It handles dozens of HEIC files far faster than Preview can work one at a time.

Stop HEIC at the Source

Choose Most Compatible on your iPhone. New photos arrive as JPEG and the conversion step disappears entirely.
