How to Convert HEIC to JPG Online Free
What is HEIC format?
HEIC (High Efficiency Image Container) is an image format developed by the MPEG group and adopted by Apple as the default photo format on iPhone and iPad since iOS 11 in 2017. HEIC uses the HEVC (H.265) compression algorithm to produce significantly smaller files than JPG while maintaining better image quality.
In other words, a HEIC photo taken on iPhone is typically half the size of an equivalent JPG photo at the same visual quality. As a result, iPhones can store roughly twice as many photos in the same storage space when using HEIC. Furthermore, HEIC supports features like transparency, 16-bit colour depth, and image sequences — capabilities that JPG does not have.
HEIC files are typically 40–50% smaller than equivalent JPG files at the same visual quality. A photo that would be 4MB as a JPG is often only 2MB as a HEIC file — which is why Apple chose it as the default iPhone camera format.
Why convert HEIC to JPG?
Despite its advantages, HEIC has a significant compatibility problem — it is not universally supported. Here are the most common reasons people need to convert HEIC to JPG:
- Windows compatibility — Windows 10 and 11 require a paid codec from the Microsoft Store to open HEIC files natively. Most Windows users cannot open HEIC photos without installing extra software.
- Android compatibility — Android phones cannot open HEIC files. If you send an iPhone photo to an Android user and it saves as HEIC, they may not be able to view it.
- Website uploads — many websites, forms, and online services only accept JPG or PNG uploads. HEIC files are rejected by most upload systems.
- Email and messaging — some email clients and messaging apps do not display HEIC images correctly, showing an error or a blank attachment instead.
- Social media — while major platforms like Instagram and Facebook now accept HEIC, many smaller platforms and tools do not.
- Editing software — older photo editing applications do not support HEIC. Converting to JPG first ensures compatibility with all editing tools.
How to convert HEIC to JPG online free — step by step
Our free image converter handles HEIC to JPG conversion directly in your browser. No software, no signup, and your photos never leave your device. Here is how to convert HEIC to JPG:
Open the image converter
Go to our free image converter. It works on Windows, Mac, and mobile browsers without any installation.
Upload your HEIC files
Drag and drop your HEIC photos or click to browse. You can upload multiple HEIC files at once for bulk conversion to JPG.
Select JPG as output format
Click JPG in the format selector. Alternatively, select WebP for even smaller files if you are preparing images for a website.
Set quality to 85–90%
For converted iPhone photos, 85–90% quality gives excellent results. The converted JPG will look virtually identical to the original HEIC photo.
Convert and download
Click Convert and download your JPG files instantly. For multiple files, use the Download All button to get all converted photos at once.
How to stop iPhone saving photos as HEIC
If you frequently need to share photos with Windows or Android users, the simplest long-term solution is to change your iPhone camera settings to save photos as JPG instead of HEIC. Here is how:
- Open the Settings app on your iPhone
- Scroll down and tap Camera
- Tap Formats
- Select Most Compatible instead of High Efficiency
After making this change, your iPhone will save all new photos as JPG. Existing HEIC photos are not converted — you will need to convert those separately. Furthermore, choosing Most Compatible slightly increases photo file sizes, but ensures universal compatibility with all devices and platforms.
You can also configure your iPhone to automatically convert HEIC to JPG when transferring photos to a PC. Go to Settings → Photos → Transfer to Mac or PC → select "Automatic". This converts photos to JPG during transfer without changing the format stored on your iPhone.
How to open HEIC files on Windows
There are three main ways to open HEIC files on Windows without converting them first:
Does converting HEIC to JPG reduce quality?
Converting HEIC to JPG does involve some quality trade-off, but at quality settings of 85% or above, the difference is essentially invisible on screen. Here is what actually happens during the conversion:
HEIC uses more advanced compression than JPG. As a result, when you convert HEIC to JPG at equivalent visual quality, the JPG file will be larger than the original HEIC. In other words, HEIC is more efficient — the same visual quality takes up less storage space in HEIC than in JPG.
However, the quality loss from converting HEIC to JPG at 85–90% quality is negligible for most practical purposes — viewing on screen, printing at standard sizes, or sharing on social media. The difference only becomes apparent at very high zoom levels or when printing very large format prints.
Keep your original HEIC files as backups before converting. HEIC stores more image data than JPG — including colour depth and dynamic range information — that cannot be recovered after conversion to JPG. For archival purposes, always keep the original HEIC.
Frequently asked questions
Why does my iPhone save photos as HEIC instead of JPG?
Apple switched to HEIC as the default iPhone camera format in iOS 11 because HEIC files are approximately 50% smaller than equivalent JPG files at the same quality. This allows iPhone users to store roughly twice as many photos in the same storage space. However, you can change this in Settings → Camera → Formats → Most Compatible to switch back to JPG.
Is HEIC better quality than JPG?
HEIC achieves better quality than JPG at the same file size due to its more efficient compression algorithm. Furthermore, HEIC supports 16-bit colour depth compared to JPG's 8-bit, which means HEIC can capture more subtle colour gradations in photos. However, for most practical viewing purposes, a high quality JPG at 90%+ looks identical to HEIC on screen.
Can I convert HEIC to JPG on iPhone directly?
Yes — when you AirDrop or share a HEIC photo from iPhone to a Mac, it is automatically converted to JPG. When you email or message a HEIC photo, iPhone often converts it to JPG automatically for compatibility. Furthermore, you can use our mobile-compatible converter — open it in Safari on your iPhone, upload your HEIC files, and download the converted JPGs directly to your Photos app.
How do I convert multiple HEIC files to JPG at once?
Our free image converter supports bulk conversion — upload as many HEIC files as you need, select JPG as the output format, and convert them all at once. All files are processed simultaneously and you can download them all with the Download All button. There are no limits on the number of files you can convert.
