Every iPhone photo taken since 2017 is saved as a .heic file. That's fine until you try to open it on a Windows PC, share it in an email, or upload it to a website that only accepts JPG. The file just doesn't work.
This guide explains what HEIC is, why your iPhone uses it, and how to convert HEIC to JPG in three steps — without installing software or uploading your photos to anyone's server.
What is HEIC and why does the iPhone use it?
HEIC stands for High Efficiency Image Container. It's a format built on the HEVC (H.265) video codec that compresses images to roughly half the size of a JPEG at the same visual quality. Apple adopted it as the default camera format in iOS 11 because it saves storage space — important when phones ship with 64GB or 128GB of storage and users take thousands of photos.
The tradeoff: HEIC isn't universally supported. Windows Photo Viewer can't open it. Chrome on Android can't display it. Many web forms reject it. Even some professional print services don't accept it. JPG, by comparison, works everywhere — every operating system, every browser, every image viewer built in the last 30 years.
HEIC vs JPG: quality comparison
HEIC produces smaller files than JPG at equivalent visual quality. A 12-megapixel iPhone photo might be 1.5 MB as HEIC and 3 MB as JPG. When you convert HEIC to JPG, the file gets larger but the image looks identical to the human eye. You aren't losing quality — you're trading compression efficiency for universal compatibility.
HEIC also supports features that JPG doesn't: 16-bit color depth, transparency (alpha channel), depth maps from Portrait Mode, and Live Photo sequences. When converting to JPG, Morph extracts the primary image at full resolution. Depth maps and Live Photo data are discarded because JPG has no way to store them.

That's it. No account, no watermark, no file size limit, no daily cap.
Why most HEIC converters are a privacy risk
Search for "HEIC to JPG" and you'll find dozens of online converters. Almost all of them work the same way: you upload your photo to their server, their server converts it, and you download the result. Your personal photo — your kids, your home, your vacation, your ID scan — sits on a server you don't control.
Some services claim to delete files after conversion. Some delete after an hour. Some don't say. The point is: you're trusting a stranger with your photos for no reason, because the conversion can happen entirely on your own device.
Batch conversion
Got a folder of HEIC files from a trip? Morph supports batch conversion — drop multiple files at once, pick JPG as the output, and download them all. Each file converts independently in your browser. This is especially useful when transferring an entire iPhone photo library to a Windows machine or uploading an album to a service that doesn't accept HEIC.
Other formats you can convert HEIC to
JPG is the most common target, but Morph can also convert HEIC to:
- PNG — lossless, supports transparency, larger files. Good for screenshots and graphics.
- WebP — modern format with excellent compression. Smaller than JPG. Supported in all current browsers.
- PDF — wraps the image in a document. Useful for sending photos as attachments that preserve formatting.
How to stop your iPhone from saving HEIC
If you'd rather avoid HEIC altogether, you can change your iPhone's camera settings. Go to Settings → Camera → Formats and select Most Compatible. This switches the default format to JPG. The downside: your photos will be roughly twice as large, so you'll fill up your storage faster.
For most people, the better approach is to keep shooting in HEIC (smaller files, same quality) and convert to JPG only when you need to share with a device or service that doesn't support it.
