How to Convert HEIC to JPG — Open iPhone Photos on Windows and Upload Forms (Free)

You've received a photo via KakaoTalk or email on your iPhone, tried to open it on a PC, and hit a wall: the file has a .HEIC extension and Paint, Hangul, and your company's upload form all say "unsupported format." iPhone cameras have shot in HEIC — a high-efficiency image format — by default since iOS 11, but Windows, Android, and most web upload fields still can't read it. The usual workarounds involve asking the sender to resend, or screenshotting and losing quality. This guide shows you how to convert HEIC to a universally readable JPG in under a minute — including batch conversion of multiple photos and bundling them into a single PDF. No installation, no sign-up.

What Is HEIC and Why Won't It Open?

HEIC (High Efficiency Image Container) is the image format Apple adopted by default starting with iOS 11 in 2017. It stores the same image quality as JPG at roughly half the file size — great for saving storage space, but compatible with far fewer applications. The Windows default photo viewer (before a separate codec is installed), older Android devices, and most file upload fields on job application, government, and shopping sites all reject HEIC. Converting to JPG before sending or uploading is the easiest way to avoid these problems.

How to Convert — 2 Steps

1. Upload your photos — Go to HEIC → JPG Convert and select or drag your HEIC files. You can upload multiple photos at once.
2. Download JPGs — Once conversion is complete, download your JPGs. Multiple photos are automatically packaged as a ZIP. Enable "Bundle into one PDF" to receive all the photos as a single PDF document instead.

Uploaded photos are used only for conversion and are not stored on the server.

Especially Handy In These Situations

• Company or school upload forms that only accept JPG — convert HEIC in advance so your upload isn't rejected.
• Organizing multiple photos into one document — use "Bundle into one PDF" to collect receipts or contract photos into a single file.
• Sending photos to Android users or older PCs — convert so the recipient can open the file immediately.

Shooting in JPG Directly on iPhone

If you'd rather skip the conversion step altogether, change your camera format. Go to iPhone Settings → Camera → Formats → Most Compatible and your iPhone will shoot JPG from that point on. Note that existing HEIC photos already on your device stay as HEIC — use the tool above to convert those in bulk.

Tools That Pair Well with This

If you're combining multiple photos into a single document, consider running them through Image Compress first to reduce their size, then bundle into a PDF. This is particularly useful when files are hitting upload size limits.

Frequently Asked Questions

Q. Can I convert multiple photos at once?
Yes. Upload multiple photos at once and they'll be packaged as a ZIP. Enable "Bundle into one PDF" and all photos will come back as a single PDF file.

Q. Will the image quality suffer?
The JPG output is saved at a quality level virtually indistinguishable from the original. For everyday use and uploads, you won't notice any difference.

Q. Is it free? Are my photos stored?
It's free. Uploaded photos are used only for the conversion process and are not saved on the server.

Q. Does it work on Android?
Yes. The tool runs in the browser, so it works on iPhone, Android, and desktop — any device with a browser.
