You AirDrop or email a batch of iPhone photos to your Windows laptop and they show up as IMG_4821.HEIC. The photo viewer won't open them, the job application site rejects them, and the online printing service says "unsupported format."
The quick fix most people find is an online converter. But those photos are of your kids, your house, your car, your passport. Uploading them to a site you've never heard of, just to change the file format, means trusting that site with the pictures and the hidden details inside them.
This guide shows how to convert HEIC to JPG inside your browser, in bulk, without uploading anything.
What HEIC is, and why some places can't open it
Since iOS 11, iPhones save photos as HEIC (High Efficiency Image Container). It keeps the same visual quality as JPG in roughly half the space, which is why Apple made it the default.
The catch is compatibility. Many Windows PCs need an extra codec to open HEIC, older Android phones and photo frames don't support it, and countless websites — job portals, government forms, print shops, marketplaces — accept only JPG or PNG. JPG works absolutely everywhere.
HEIC vs JPG at a glance
| HEIC | JPG | |
|---|---|---|
| File size | Smaller (about half) | Larger |
| Opens on Windows without extras | Often not | Yes |
| Accepted by websites and print shops | Rarely | Almost always |
| Best for | Storing photos on your iPhone | Sharing, uploading, printing |
There's no need to convert your whole library. Keep HEIC on your phone, where it saves space, and convert only the photos you need to send somewhere that doesn't accept it.
Why not just use an online converter
Photos carry more than pixels. An iPhone photo usually includes metadata — the exact GPS location where it was taken, the date and time, and the phone model. When you upload a photo to a converter, all of that goes along with it, to a server you can't inspect.
A client-side converter keeps everything on your device: the web page loads the decoder into your browser, converts the photos in memory, and hands the JPGs straight back to you.
How NoUpload converts HEIC
NoUpload's HEIC to JPG tool reads each photo on your device and redraws it as a JPG:
- In Safari (on iPhone, iPad and Mac), it uses the browser's own built-in HEIC support.
- In Chrome, Edge and Firefox, which can't open HEIC natively, it loads an open-source HEIC decoder (libheif) — served from lunibyte.com and run locally in your browser.
Either way, your photos never leave your device. And because each image is redrawn from scratch, the resulting JPGs contain no location, camera or date information — a privacy bonus that makes them safer to share.
Step-by-step
- Open the tool: lunibyte.com/noupload/heic-to-jpg.html.
- Add your photos. Drop HEIC or HEIF files into the box, or click (tap) to choose them. Add as many as you like.
- Choose a quality. The slider defaults to 92%, which looks identical to the original for almost every photo. Lower it if you need smaller files.
- Tap Convert. Each photo is converted in turn; the first HEIC can take a few seconds while the decoder starts.
- Download. A single photo downloads straight away. For several, download them one by one from the list, or tap Download all (.zip) to get them in one file.
On Windows
Drag HEIC files from File Explorer straight into the box, convert, and save the JPGs or the .zip to your Pictures folder. No codec or app install needed.
On iPhone
Open the page in Safari, tap the box and choose Photo Library or Browse (Files). After converting, tap the download in Safari and save it to Files, or share it directly.
Prefer to avoid HEIC altogether?
Two iPhone settings can save you the conversion step:
- Shoot JPG from now on: Settings → Camera → Formats → Most Compatible. New photos are saved as JPG (files are larger, and some features like 48 MP ProRAW don't apply).
- Auto-convert when copying to a computer: Settings → Photos → Transfer to Mac or PC → Automatic. Photos copied over a cable arrive as JPG.
Neither setting changes the photos already on your phone — that's where a converter helps.
When converting makes sense
A few everyday situations where a quick conversion saves the day:
- Job and rental applications that ask for a photo of your ID or a document and accept only JPG or PNG.
- Online print orders — photo books, canvases and prints — where HEIC uploads are rejected.
- Sharing with family on Windows PCs or older Android phones, so they can simply double-click to open.
- Marketplace listings, where photos must be JPG and, ideally, free of location data.
In each case, converting locally means the original photos — and the personal details inside them — stay on your device.
Tips
- Very large photos: iPhone Safari limits images to about 16 megapixels in the browser. Larger photos (for example 48 MP shots) are resized slightly so every browser can handle them; the tool tells you when that happens.
- Need a PDF instead? Convert to JPG, then combine them with JPG to PDF.
- Sharing location-sensitive photos that are already JPG? Use Remove Photo Location — see our guide to removing GPS from photos.
Frequently asked questions
Will the quality drop? JPG is a compressed format, but at the default 92% the difference is invisible for everyday viewing, sharing and printing.
Is EXIF data kept? No. The JPGs NoUpload creates contain no location, camera or date information, so they are safer to share. Keep the original HEIC if you need that information.
Can I convert many photos at once? Yes — drop in as many as you like and download them all as a single .zip.
What about HDR photos? They convert fine. The result is a standard JPG, so the extra HDR brightness some iPhones show on supported screens isn't kept — the photo looks like it does on any ordinary display.
Will my photos be rotated correctly? Yes. NoUpload reads the orientation your iPhone stored with each photo, so portrait shots stay portrait in the JPG.
What about Live Photos? You get the still photo as a JPG. The short video part of a Live Photo isn't included.
Can I convert to PNG instead? This tool creates JPGs, which are smaller and accepted almost everywhere. If a site insists on PNG, Remove Photo Location keeps PNG files as PNG.
How many times can I use it? Your first 3 uses of any NoUpload tool are included — no signup, no watermark. After that, NoUpload Pro unlocks unlimited use of every tool.
