6 HEIC to JPG Conversion Methods Ranked (Best to Worst)
The iPhone Photo Format Nobody Asked For
You take a beautiful photo on your iPhone, transfer it to your Windows laptop or try to upload it to a website, and suddenly nothing works. The file is not a JPEG. It is not a PNG. It is something called HEIC, and your computer has no idea what to do with it.
If this sounds familiar, you are not alone. Since 2017, Apple has used the High Efficiency Image Container (HEIC) format as the default photo format on iPhones and iPads. The format — based on the HEIF (High Efficiency Image Format) standard and typically using HEVC compression — produces files that are roughly 40-50% smaller than equivalent JPEGs while maintaining comparable or even better visual quality. From Apple's perspective, it is a no-brainer: your 128 GB iPhone can store significantly more photos without sacrificing quality.
The problem is that the rest of the world has not caught up. Windows support for HEIC was patchy until relatively recently, many websites and content management systems reject HEIC uploads, and most image editing tools outside the Apple ecosystem either cannot open the files or require plugins to do so. Email clients, social media upload forms, online printing services, and countless other workflows still expect JPEG.
So you need to convert. The question is: what is the best way to do it? In this article, we rank six common HEIC to JPG conversion methods from best to worst, comparing them on speed, quality, privacy, convenience, and flexibility.
Why You Need to Convert HEIC Files
Before diving into the methods, let us briefly cover the situations where HEIC to JPG conversion is necessary:
- Sharing with non-Apple users. If you send HEIC files to someone on Windows or Android, they may not be able to open them without installing additional software.
- Uploading to websites. Many CMS platforms, e-commerce sites, and social media upload forms do not accept HEIC. You will see an "unsupported format" error.
- Printing services. Online photo printing services almost universally require JPEG or PNG.
- Email attachments. While Apple's Mail app can auto-convert when sharing, other email clients may send the raw HEIC file, which recipients cannot open.
- Editing in non-Apple software. Tools like older versions of Photoshop, GIMP, Canva, and many others require JPEG or PNG input.
- Archival and compatibility. JPEG has been the universal image standard for over 30 years. If long-term compatibility matters, JPEG remains the safest bet.
Method 1: Online Browser-Based Tools (Best)
Ranking: Best overall
Online conversion tools are the fastest, most convenient way to convert HEIC files to JPG for the vast majority of users. You open a website, drag in your files, and download the converted JPEGs. No software to install, no accounts to create, and it works on any device with a browser — Windows, Mac, Linux, Chromebook, even your phone.
The best online converters, like our HEIC to JPG tool, process your files entirely in the browser using JavaScript. This is an important distinction. Client-side processing means your photos never leave your device. They are not uploaded to a server, not stored in someone else's cloud, and not accessible to anyone but you. For photos of your family, documents, or anything else private, this matters enormously.
Advantages:
- No installation required
- Works on every operating system and device
- Client-side tools keep your files completely private
- Usually supports batch conversion (multiple files at once)
- Free to use
- Output quality is typically configurable
Disadvantages:
- Requires an internet connection to load the tool (though client-side tools process offline after loading)
- Very large batches (hundreds of files) may be slower than native desktop apps
Best for: Anyone who needs quick, occasional conversions without installing software. Also ideal for users on shared or work computers where they cannot install applications.
Method 2: Change iPhone Settings (Prevent the Problem)
Ranking: Excellent for prevention
If you are tired of dealing with HEIC files entirely, you can tell your iPhone to shoot in JPEG from the start. This does not help with photos you have already taken, but it prevents the problem going forward.
How to do it:
- Open Settings on your iPhone
- Scroll down and tap Camera
- Tap Formats
- Select Most Compatible instead of High Efficiency
When set to "Most Compatible," your iPhone will save photos as JPEG and videos as H.264 (MOV) instead of HEIC and HEVC. The trade-off is larger file sizes — you will use roughly 40-50% more storage per photo — but you will never have a compatibility issue again.
There is also a useful middle-ground setting. Under Settings > Photos > Transfer to Mac or PC, you can choose Automatic. This tells your iPhone to keep shooting in HEIC (saving storage on the device) but automatically convert to JPEG when you transfer files via USB or AirDrop to a computer. This gives you the best of both worlds, though it only applies to wired transfers and AirDrop, not cloud sync or email.
Advantages:
- Eliminates the problem at the source
- No conversion step needed
- Simple one-time setting change
Disadvantages:
- Does not convert existing HEIC photos
- Uses more storage on your iPhone
- Slightly lower compression efficiency compared to HEIC
- You lose the quality advantages of HEIC
Best for: Users who regularly share photos with non-Apple users and want to avoid conversion entirely.
Method 3: macOS Preview (Built-In Mac Solution)
Ranking: Good for Mac users
If you are on a Mac, you already have a capable HEIC to JPG converter built into the operating system. The Preview app can open HEIC files natively and export them as JPEG, PNG, TIFF, and several other formats.
How to convert a single file:
- Open the HEIC file in Preview
- Click File > Export
- Choose JPEG from the Format dropdown
- Adjust the quality slider (80-90% is usually a good balance)
- Click Save
How to batch convert multiple files:
- Select all the HEIC files you want to convert in Finder
- Right-click and choose Open With > Preview
- In Preview, press Command+A to select all images in the sidebar
- Click File > Export Selected Images
- Click Options at the bottom of the dialog
- Choose JPEG as the format
- Select a destination folder and click Choose
This batch method works well for dozens of files. For hundreds or thousands, it can be slow, and you have limited control over output settings compared to dedicated tools.
Advantages:
- Already installed on every Mac
- No internet connection required
- Supports batch conversion
- Full control over JPEG quality level
- Completely private — everything stays on your machine
Disadvantages:
- Mac only — not available on Windows or Linux
- Batch workflow is not intuitive (most people do not know about it)
- Slow for very large batches
- No drag-and-drop convenience
Best for: Mac users who need occasional conversions and prefer not to use online tools.
Method 4: Windows Apps and Codecs (Functional but Fiddly)
Ranking: Adequate
Windows did not support HEIC natively for years, but Microsoft has gradually improved the situation. There are now two paths for Windows users: install the HEIC codec for system-wide support, or use third-party conversion apps.
Option A: Install the HEIF Image Extensions
Microsoft offers a free HEIF Image Extensions package in the Microsoft Store that lets Windows open and display HEIC files in Photos, File Explorer, and other apps. However, to actually decode HEVC-compressed images (which is what most iPhone HEIC files use), you also need the HEVC Video Extensions, which Microsoft charges a small fee for (around $0.99). There is a free version called "HEVC Video Extensions from Device Manufacturer" that you can find if you search carefully.
Once installed, you can open HEIC files in the Windows Photos app and use Save As to export as JPEG. It works, but it is a one-file-at-a-time process with no batch support.
Option B: Third-party apps
Several free and paid Windows applications offer HEIC to JPG conversion with batch support:
- iMazing HEIC Converter (free) — simple drag-and-drop interface, batch capable
- CopyTrans HEIC — adds HEIC support to Windows and includes a right-click conversion option
- XnConvert — powerful batch image converter supporting dozens of formats
Advantages:
- Works offline
- Some apps support batch conversion
- The codec approach adds system-wide HEIC support
Disadvantages:
- Requires installing software (or paying for codecs)
- The codec situation on Windows is confusing
- Third-party apps vary in quality and may include bundled software
- More steps involved than online tools
Best for: Windows users who regularly work with HEIC files and want native support or a dedicated desktop app.
Method 5: Cloud Storage Auto-Conversion (Passive but Limited)
Ranking: Below average
If you use a cloud storage service, you may already have access to automatic HEIC conversion without realizing it.
Google Photos is the most notable example. When you upload HEIC files to Google Photos and then download them to a non-Apple device, Google automatically converts them to JPEG. This happens silently in the background. The catch is that Google may also compress your images according to your storage plan settings, and you have no control over the JPEG quality level.
iCloud works similarly when accessed from a Windows browser. If you go to iCloud.com and download photos, Apple offers a JPEG conversion option. However, the download process is slow, and you are limited in how many files you can download at once.
OneDrive and Dropbox have also added HEIC viewing support, though their conversion capabilities are more limited.
Advantages:
- Happens automatically if you already use these services
- No additional software needed
- Works across devices
Disadvantages:
- No control over output quality
- Cloud services may apply additional compression
- Your photos are uploaded to third-party servers (privacy concern)
- Slow for large libraries
- Dependent on your internet upload speed
- May count against your storage quota
Best for: Users who already store their photos in Google Photos or iCloud and do not need precise control over conversion quality.
Method 6: Command-Line Tools (For Developers Only)
Ranking: Worst for general users, great for developers
If you are comfortable with the terminal, command-line tools offer the most powerful and scriptable approach to HEIC conversion. The two main options are ImageMagick and libheif.
Using ImageMagick:
# Convert a single file
magick input.heic output.jpg
# Batch convert all HEIC files in a directory
for f in *.heic; do magick "$f" "${f%.heic}.jpg"; done
# Convert with specific quality
magick input.heic -quality 85 output.jpg
Using libheif (heif-convert):
# Install on macOS
brew install libheif
# Convert a single file
heif-convert input.heic output.jpg
# Batch convert
for f in *.heic; do heif-convert "$f" "${f%.heic}.jpg"; done
These tools give you complete control over every parameter: quality, resolution, color space, metadata handling, and more. You can write scripts to process thousands of files, integrate conversion into automated workflows, and pipe output to other tools.
Advantages:
- Maximum control and flexibility
- Scriptable and automatable
- Can handle thousands of files efficiently
- Free and open source
- No privacy concerns — everything runs locally
Disadvantages:
- Requires command-line knowledge
- Requires installing developer tools (Homebrew, ImageMagick, etc.)
- No visual interface
- Error messages can be cryptic
- Overkill for casual use
Best for: Developers, system administrators, and power users who need to process large volumes of files or integrate conversion into automated pipelines.
Quality Comparison Across Methods
One of the most common concerns when converting from HEIC to JPG is quality loss. Here is what you need to know: every conversion from HEIC to JPEG involves some quality loss because you are transcoding from one lossy format to another. However, the amount of loss varies by method and settings.
At a JPEG quality setting of 90-95%, the visual difference between the original HEIC and the converted JPEG is virtually imperceptible to the human eye. You would need to zoom in to 200% or more and compare specific regions side-by-side to notice any artifacts.
The methods that give you control over the JPEG quality slider (online tools, Preview, command-line) will generally produce better results than those that make the decision for you (cloud storage auto-conversion). If quality matters, always choose a method that lets you set the output quality to at least 85%.
HEIC vs JPEG: File Size and Quality Comparison
To give you a concrete sense of the differences, here is a comparison based on a typical 12-megapixel iPhone photo:
| Metric | HEIC | JPEG (Quality 85%) | JPEG (Quality 95%) | |---|---|---|---| | File size | ~1.8 MB | ~2.5 MB | ~5.2 MB | | Visual quality | Excellent | Very good | Excellent | | Detail preservation | High | Good | Very high | | Compatibility | Apple ecosystem | Universal | Universal | | Editing flexibility | Limited tool support | Full tool support | Full tool support | | Metadata support | Full EXIF | Full EXIF | Full EXIF | | Transparency | Supported | Not supported | Not supported | | Animation | Supported | Not supported | Not supported |
The key takeaway from this table is that HEIC delivers comparable quality at significantly smaller file sizes. But that storage advantage is only useful if you stay within the Apple ecosystem. The moment you need to share, edit, print, or upload outside of Apple, JPEG's universal compatibility wins.
If you frequently work with images and need to optimize them for the web after conversion, tools like our JPEG compressor can help you find the sweet spot between file size and visual quality. And if you need to convert between other image formats as well, check out our PNG to JPG converter or WebP converter for additional options.
Which Method Should You Use?
The right conversion method depends entirely on your situation. Here is a quick decision guide:
-
"I just need to convert a few photos right now." Use an online browser-based tool. It is the fastest path from HEIC to JPG with zero setup.
-
"I am tired of dealing with HEIC entirely." Change your iPhone's camera format setting to Most Compatible. Problem solved going forward.
-
"I am on a Mac and prefer to work offline." Use Preview. It is already on your computer and handles batch conversion reasonably well.
-
"I am on Windows and work with HEIC files regularly." Install a dedicated converter app like iMazing HEIC Converter, or add the HEIC codec for system-wide support.
-
"I store everything in Google Photos anyway." Let the cloud handle it. Your downloads will be JPEG automatically, though you sacrifice quality control.
-
"I need to process hundreds of files in an automated workflow." Go with command-line tools like ImageMagick. Nothing else matches the power and flexibility.
For most people, the answer is straightforward: use an online tool for occasional conversions and change your iPhone settings if you want to prevent the problem from recurring. These two approaches, used together, cover 95% of use cases.
Conclusion
The HEIC format exists for a good reason — it saves significant storage space on your iPhone without sacrificing photo quality. But until the rest of the technology world fully embraces HEIC, you will occasionally need to convert your files to JPEG for sharing, uploading, editing, or printing.
The six methods we ranked in this article cover every scenario, from the casual user who just needs to convert a vacation photo to the developer building an automated image processing pipeline. The ranking reflects a balance of convenience, quality control, privacy, and accessibility, but your specific needs may shift the order.
