Convert HEIC to JPG
Can’t open iPhone photos on Windows or in a web form? Turn HEIC files into JPG here – on your device, without uploading a single photo.
Source: ITU-T T.81 / ISO/IEC 10918-1 – JPEG. Updated: .
How it is calculated
Since iOS 11, iPhones save photos as HEIC by default (High Efficiency Image Container, part of the HEIF standard). At the same quality it needs much less storage than JPG. The catch: Windows PCs without an extra extension, many web forms, government portals and older apps can’t open HEIC. This tool converts your photos to JPG, which opens everywhere.
How it works
- Drag in or choose your HEIC photos (up to 20 at once).
- With the first photo, your browser loads a HEIC decoder once (about 2 MB, open source). Safari on Mac, iPhone and iPad reads HEIC natively and doesn’t need it.
- Download the JPGs one by one or all as a ZIP.
Quality and file size
JPG compresses less efficiently than HEIC, so the JPG is usually larger than the original. At 90% quality there is no visible difference; if you need smaller files, lower the quality or run them through the image compressor afterwards. Choose PNG if you need lossless quality (larger files).
Get JPG instead of HEIC on your iPhone
To shoot JPG from now on: Settings → Camera → Formats → “Most Compatible”. Photos then take up more space. When transferring to a computer, the iPhone can also convert automatically: Settings → Photos → “Transfer to Mac or PC” → “Automatic”.
Opening HEIC on Windows
Windows 10 and 11 only display HEIC photos after installing the “HEIF Image Extensions” and “HEVC Video Extensions” from the Microsoft Store. Converting here is the simpler option if you want to share or upload the photos.
What about Live Photos and metadata?
The main image is converted; the video part of a Live Photo is a separate file and stays untouched. Orientation is applied, while EXIF data such as location (GPS) and camera model is not written to the JPG – good for privacy when you share photos.
Privacy
Your photos never leave your device. The decoder (libheif, open source under LGPL-3.0) is loaded as program code; the photos themselves are processed locally only.
More image tools: convert WebP or AVIF with the image converter, shrink large JPGs with the image compressor, change pixel dimensions with resize image, and put several photos into one document with images to PDF.
Frequently asked questions
Is the conversion really done without uploading?
Yes. HEIC files are read by a WebAssembly decoder in your browser. No photo is sent to a server.
Why is the JPG larger than the HEIC file?
HEIC uses the more modern HEVC compression and is much smaller than a JPG at the same quality (Apple: “better compression than JPEG”). Lower the quality to 80% if you need smaller JPGs.
Can I convert several HEIC photos at once?
Yes, up to 20 photos per batch. “Download all as ZIP” gives you all JPGs in one file.
Does it work on iPhone or Android?
Yes, in any current browser. On iPhone, Safari reads HEIC natively, which makes it especially fast.
Are the capture date and location kept?
No, EXIF metadata is not carried over. The image itself, its size and its orientation are kept.
How do I switch my iPhone to JPG permanently?
Settings → Camera → Formats → “Most Compatible”. New photos are then saved as JPG but take up more space.
What’s the difference between HEIC and HEIF?
HEIF is the container format standard; HEIC is the variant with HEVC-compressed images that Apple uses. Both extensions are supported here.
How do I convert HEIC to JPG on Windows 11?
Open this page in Edge, Chrome or Firefox, drop in the HEIC files and convert – no extra software needed. To open HEIC files in Windows itself, install the HEIF Image Extensions from the Microsoft Store.
