You took a photo of your marksheet with your iPhone, sent it to your laptop and Windows refused to open it. Or a government portal rejected your photo with "invalid file type". The reason is almost always the same: the photo is in HEIC format. This guide explains what HEIC is, why so many websites still do not accept it, and how to convert HEIC photos to JPG quickly, in bulk and without uploading them anywhere.
What is HEIC?
HEIC (High Efficiency Image Container, also called HEIF) is the default photo format on iPhones and iPads since iOS 11. It stores photos at roughly half the size of a JPG of similar quality, which saves storage space on your phone. It can also hold extras such as Live Photo data and depth information for portrait mode.
The problem is compatibility. JPG has been the universal image format for decades, and almost every system understands it. HEIC is newer and uses patented compression, so many programs do not support it out of the box:
- Older Windows versions need an extra codec from the Microsoft Store to show HEIC files.
- Many online forms, including exam, job and government portals, accept only JPG/JPEG, and sometimes PNG or PDF.
- Some Android phones, older photo editors and printing shop computers cannot open HEIC.
Convert HEIC to JPG in your browser
- Open HEIC to JPG on your iPhone, Windows PC, Mac or Android phone.
- Select one or many .heic files. You can select a whole folder of holiday photos at once.
- Choose JPG (smallest files, best compatibility) or PNG (lossless, larger files).
- Convert and download. With many files, download them all together as a ZIP archive.
The conversion runs on your device using JavaScript, so your personal photos are not uploaded to any server. This matters for photos of documents such as Aadhaar cards, passports and cheques.
Getting HEIC files off your iPhone
Depending on how you transfer photos, the iPhone may convert them automatically or keep them as HEIC:
- Sharing to apps or websites from the Photos app often converts to JPG automatically. Uploading straight from the Files app keeps the original format.
- USB cable to Windows: on the iPhone go to Settings → Photos → Transfer to Mac or PC. "Automatic" converts to JPG during transfer; "Keep Originals" copies HEIC files.
- AirDrop to a Mac: keeps HEIC, which macOS can open but other systems may not.
- WhatsApp, Telegram, email: sending as a photo usually converts and compresses it; sending as a document keeps HEIC.
- iCloud Photos on the web: lets you download either the original or a "Most Compatible" version.
Stop the iPhone from creating HEIC files
If you often need JPGs, you can switch the camera to JPG: open Settings → Camera → Formats and choose Most Compatible. New photos will be saved as JPG and take about twice the storage space. Existing photos are not changed, so convert those with the tool above.
Quality and size after conversion
Converting HEIC to JPG keeps the same resolution. Because JPG is less efficient, the file size grows, often from 1.5 MB to 2–4 MB per photo. That is fine for printing or sharing, but too large for many online forms. After converting:
- Use Compress JPG to reduce general file size, or Compress Image to 50 KB for strict limits. Our guide to compressing images to 20 KB or 50 KB explains how to keep text and faces sharp.
- For exam photographs, follow our photo and signature resize guide and the official notice for exact dimensions.
- For documents, combine the converted photos into one file with JPG to PDF.
Other formats you might meet
HEIC is not the only newer image format. Some websites deliver images as WEBP and some phones and apps use AVIF. They have the same advantage (smaller files) and the same disadvantage (patchy support). Ocr4you has converters for these too: AVIF to JPG and Image to JPG, which accepts WEBP, PNG, BMP and more.
Troubleshooting
The converted photo is rotated
Phones store orientation as a tag rather than rotating the pixels. Most viewers respect it, but some forms do not. Fix it with Rotate Image.
Conversion is slow on my phone
HEIC decoding is demanding. Converting 100 photos on an older phone can take a few minutes. Convert in batches of 20–30, or use a computer.
Live Photos lose the motion
JPG is a still image format, so only the key photo is kept. The video part of a Live Photo is a separate file.
Is any metadata kept?
Basic image data is converted; location and camera details may not all be kept. If you share photos publicly, removing location data is generally a good thing for privacy.
Summary
HEIC saves space on your iPhone but causes trouble with forms, Windows and older software. Convert to JPG in your browser with HEIC to JPG, compress if a size limit applies, and switch the camera to "Most Compatible" if you need JPG every day.
