You just transferred photos from your iPhone to your laptop, and now half of them won't open. Instead of the familiar .jpg extension, you're staring at a bunch of files ending in .heic. What is that, and why won't anything read it?
You're not alone. This is one of the most common photo frustrations for iPhone and iPad users. The good news: converting HEIC to JPG is fast, free, and works on every major device and operating system. This guide walks you through exactly how to do it — no technical background required.
What Is a HEIC File, Anyway?
HEIC stands for High Efficiency Image Container. Apple adopted it as the default photo format starting with iOS 11 (2017) because it compresses images to roughly half the file size of a JPEG — without a visible drop in quality. Great for saving storage space on your phone. Not so great when you need to share those photos with someone on Windows, upload them to a website, or print them.
The problem is simple: HEIC is an Apple-native format. Most non-Apple software, older apps, and web platforms still expect the universally supported .jpg format. That's why knowing how to convert a HEIC file to JPG is a genuinely useful skill in 2024.
How to Convert HEIC to JPG on iPhone (Before You Even Transfer)
The easiest fix is to stop your iPhone from shooting HEIC in the first place — or to have it automatically convert photos when you share them.
Option 1: Change Your Camera Format
- Open Settings on your iPhone.
- Scroll down and tap Camera.
- Tap Formats.
- Select Most Compatible instead of "High Efficiency."
Your camera will now save photos as JPG by default. Simple — but it does mean slightly larger file sizes going forward.
Option 2: Auto-Convert When Transferring
- Go to Settings → Photos.
- Scroll to the bottom and find Transfer to Mac or PC.
- Select Automatic.
With this setting, your iPhone will quietly convert HEIC to JPG whenever you transfer photos via USB. The photos on your phone stay in HEIC; what lands on your computer is JPG. Best of both worlds.
How to Convert HEIC to JPG on Windows 11
Windows 11 has improved HEIC support, but it's still not seamless out of the box. Here are your most reliable options.
Method 1: Use the Photos App (With a Free Codec)
Windows 11's Photos app can open HEIC files if you install the free HEVC Video Extensions codec from the Microsoft Store. Once installed:
- Open the HEIC file in the Photos app.
- Click the three-dot menu (⋯) in the top right.
- Select Save as and choose JPEG from the format dropdown.
Method 2: Use Paint
Once the codec above is installed, you can also open a HEIC file in Paint (yes, classic Paint), then go to File → Save as → JPEG image. It's clunky but it works in a pinch.
Method 3: Use a Free Online Converter
If you'd rather not install anything, dozens of free browser-based tools convert HEIC to JPG instantly. Search for "HEIC to JPG converter online," upload your file, download the result. Most handle batch conversions too, so you can convert photos from HEIC to JPG in bulk without doing them one at a time.
How to Convert HEIC to JPG on Android
Android doesn't natively support HEIC files, so if someone sends you one or you're working across devices, you'll need a workaround.
Use a Conversion App
The Google Play Store has several free apps designed specifically for this. Search for "HEIC to JPG converter" and look for highly-rated options with recent updates. Most work like this:
- Open the app and tap Select Files.
- Choose your HEIC image(s) from your gallery or file manager.
- Tap Convert and save the resulting JPG to your device.
Use a Browser-Based Tool on Android
You don't even need an app. Open Chrome on your Android device, navigate to any free HEIC-to-JPG converter, upload the file, and download the JPG. It works just as well on mobile as on desktop.
How to Convert HEIC to JPG on Mac
Mac users have it easiest. macOS natively reads HEIC files, and converting them takes about ten seconds.
- Open the HEIC file in Preview (the default image viewer on Mac).
- Go to File → Export.
- In the Format dropdown, select JPEG.
- Adjust the quality slider if needed, then click Save.
To batch-convert multiple files: open them all in Preview at once, select all thumbnails in the sidebar, then go to File → Export Selected Images.
How to Convert HEIC to PDF
Sometimes you don't need a JPG — you need a PDF. Maybe you're compiling photos into a document, submitting images for a form, or archiving a set of photos in a single shareable file. Converting HEIC to PDF follows similar logic:
- On Mac: Open the HEIC in Preview → File → Export as PDF.
- On iPhone: Open the photo → tap Share → Print → pinch-zoom the print preview to open it as a PDF → Share again to save.
- On Windows: Convert to JPG first (using any method above), then use a tool like WriteGenius's PDF Editor to work with your images in a PDF workflow — whether you need to combine them, annotate, or prepare them for sharing.
If you frequently work with images and documents together, it's worth bookmarking a reliable PDF tool. The WriteGenius PDF Editor handles common document tasks right in your browser, no software installation needed.
Batch Converting: How to Convert Multiple HEIC Files at Once
If you've got an entire camera roll to convert, doing files one at a time isn't practical. Here's how to handle bulk conversion efficiently:
- Mac (Preview): Select all HEIC files in Finder → right-click → Open With → Preview. Then File → Export Selected Images → choose JPEG. Done.
- Windows: Free tools like IrfanView or XnConvert support batch conversion. Add your HEIC files, set the output format to JPG, and convert them all in one go.
- Online tools: Sites like iLoveIMG and Convertio accept multiple files at once and zip up the JPGs for easy download.
- iPhone (Google Photos): If you back up your photos to Google Photos, it stores them in a web-friendly format. You can then download them as JPGs directly from the Google Photos website on your computer.
Quick Tips to Keep in Mind
- Quality loss is minimal. Converting HEIC to JPG at high quality settings produces results that are virtually indistinguishable from the original.
- File size will increase. JPG files are larger than HEIC, so don't be alarmed when your converted photos take up more space.
- Metadata may carry over — or not. Location data, timestamps, and camera info sometimes survive conversion, but not always. If metadata matters to you, check the output file.
- Keep originals. Always keep a backup of your original HEIC files before bulk converting. Storage is cheap; re-shooting those photos isn't.
What About Sharing or Publishing Those Converted Photos?
Once your photos are in JPG format, you might want to use them in a document, presentation, or written piece. If you're putting together a visual presentation that includes your converted images, the WriteGenius Presentation Creator lets you build polished, shareable slide decks directly in your browser — no PowerPoint license required.
And if you're writing captions, descriptions, or any text to accompany your photos, the WriteGenius Grammar Checker can help you polish that copy quickly before it goes live.
The Bottom Line
HEIC is a genuinely clever format — it's why your iPhone can store thousands of photos without running out of space. But the world hasn't fully caught up with it yet, which means knowing how to convert HEIC to JPG is just a practical skill to have.
Whether you're on a Windows 11 PC, an Android phone, a Mac, or just trying to sort this out before transferring files, the methods above cover every common scenario. Pick the one that fits your situation, convert your photos, and get on with the rest of your day.
