Convert iPhone HEIC photos to JPG on Mac
To convert an iPhone HEIC photo to JPG on a Mac, open it in Preview, choose File > Export, and set Format to JPEG. Finder's Convert Image quick action handles files without opening Preview, while sips can process a folder in Terminal. Keep the HEIC originals as masters and make JPG copies for websites or older apps that need them, because conversion can lose image information.
Why the iPhone saves HEIC photos
HEIF is an image container, and Apple uses the .HEIC extension for images compressed with HEVC. Its compression uses less storage than JPEG at comparable visual quality. A HEIC photo can also carry auxiliary information, such as a depth map, beyond the picture you see.
On the iPhone, open Settings > Camera > Formats. High Efficiency uses the space-saving formats; Most Compatible makes new photos JPEG and new videos H.264. Apple documents both choices, and changing this setting affects future captures, not HEIC files already in your library.
For an occasional upload, keeping High Efficiency and converting the required pictures avoids changing how the rest of your library is captured. If a regular workflow needs JPEG at capture, Most Compatible is the relevant camera choice.
Keep capture and transfer settings separate
The camera setting decides what gets recorded. USB transfer can make a compatible copy later, so a phone that shoots HEIC can still deliver JPEG to a computer.
For preservation, Apple's current instructions are Settings > Apps > Photos, then scroll down and select Keep Originals. This prevents the format conversion that can occur when importing into Photos or Image Capture. Apple's USB guidance says media might be converted, so importing alone is not a reliable way to request a JPG.
Older instructions describe Automatic under Transfer to Mac or PC. Adobe's Elements 2019 guide documents that compatibility option, but its Settings > Photos path predates the current Apps navigation. For a predictable JPG, preserve the source and explicitly export JPEG on the Mac.
Get the files with Image Capture or Photos
Image Capture is enough when you want a folder of files. Connect the iPhone by cable, unlock it, accept any trust prompt, then follow Apple's import steps.
- Open Image Capture and select the iPhone under Devices.
- Choose a destination from Import To, or select Other for another folder.
- Select the pictures and click Download, or use Download All.
Choose Keep Originals on the phone first if these files will be your masters. A Live Photo downloads as a still image and a separate video, so keep both files together.
If the pictures already live in Mac Photos, select them there and choose File > Export > Export [number] Photos. Set Photo Kind to JPEG, choose the export options, then click Export and choose the destination. To save masters instead, use File > Export > Export Unmodified Original. Apple's export guide distinguishes these routes.
For the initial cable import into Photos and other transfer choices, use the separate iPhone-to-Mac photo transfer guide.
Convert a file with Preview
Preview gives you a visible quality control and a destination picker without installing anything.
- Open the HEIC file in Preview.
- Choose File > Export.
- In Format, select JPEG and adjust the quality control.
- Choose a new name or destination, then click Save.
Apple's Preview instructions also cover batch conversion: open several images in one window, select them in the sidebar, then export. If a desired format is missing, hold Option while opening the Format menu to reveal additional formats.
Save into a separate folder when preparing upload copies. Open a result before converting a large selection, particularly when the image contains small text or fine detail.
Convert from Finder
In Finder, Control-click a HEIC file and choose Quick Actions > Convert Image. Choose JPEG and the image size you need. This is useful when the file is already in a folder and you do not need Preview's quality slider.
Available quick actions depend on the file type and enabled Finder extensions. If Convert Image is absent, check the action's customization options or use Preview instead. Apple's Finder guide explicitly includes converting iPhone HEIC files to JPEG or PNG.
Convert a folder with sips
The Mac includes sips, a command-line image tool. With Terminal's working directory set to the folder containing your photo, this command writes a JPEG copy to the named output:
sips -s format jpeg IMG_0421.HEIC --out IMG_0421.jpg
-s format jpeg selects the output format, and --out provides its destination. Use a new output name so you do not replace an earlier copy. Renaming .HEIC to .jpg alone does not perform this encoding step.
For a folder, the following loop is for zsh. Run it from the folder containing the exported HEIC files, rather than from a parent folder:
mkdir -p JPG
for file in ./*.[Hh][Ee][Ii][Cc](N.); do
output="JPG/${file:t:r}.jpg"
[[ -e "$output" ]] && continue
sips -s format jpeg "$file" --out "$output" || break
done
It handles upper- and lowercase extensions, writes into JPG, and leaves the HEIC sources alone. The glob selects regular files in this folder only; it does not descend into subfolders, and an empty match does nothing. Existing output names are skipped, and a failed conversion stops the loop, so inspect the destination rather than assuming every input produced a new copy.
Export with Yado, then convert on the Mac
Yado is another folder-export route if you want to browse the phone's library before selecting pictures. Its Photos tab uses a USB cable. If you only need a straightforward import, Image Capture already provides that.
- In Yado, open Photos and keep Library selected.
- Click Select Photos and tick the pictures.
- Click Export to Mac, choose a destination, then click Choose Folder.
Yado exports the available source files without an image-conversion step; it is not a HEIC-to-JPG converter. In Settings, Photo Export Names has an Original Name option, selected by default, with the example IMG_0421.HEIC. Naming a file and encoding its image are separate operations.
Keep the exported HEIC files, then use Preview, Finder or sips for JPG copies. For inspecting pictures before selection, see previewing iPhone photos on Mac.
What a JPG copy can lose
A normal JPEG export re-encodes the image with lossy compression. A high-quality copy may look very close, but further lossy re-encodes can discard more information. Make new delivery copies from the master instead of repeatedly converting the last JPG.
Depth and HDR need separate consideration. HEIC can carry a depth map, and HDR photos can contain a gain map that helps reconstruct bright highlights. An ordinary conversion may omit that auxiliary data even when the visible picture survives. JPEG can also carry depth information and Adaptive HDR, so the extension alone does not prove what was preserved. Apple's depth explanation and HDR session describe those capabilities.
A JPG by itself also does not preserve a complete Live Photo with its paired video. Keep the original still and video together when motion matters; a static upload copy serves a different purpose.
Check the result before using it
Open the new file in Preview and compare its crop, orientation, fine detail and highlights with the source. Then try the JPG in the actual website or older app that prompted the conversion. Successful viewing on your Mac does not establish that the destination accepts it.
If Preview cannot open the source either, return to the transfer step and download that picture again. If files are missing before conversion, check the connection and whether originals are available on the phone; the missing iPhone photos guide covers that problem.
For a wrong-looking JPG, export another copy from the HEIC master and review the quality and size choices. If preserving Portrait depth, HDR behavior or Live Photo motion matters more than compatibility, retain the original files even after the JPG upload succeeds.
