HEIC vs JPG: What's the Difference and How to Convert

What Is HEIC?

If you have ever transferred photos from an iPhone to a Windows PC or tried to upload a photo to a website only to get an error, you have run into the HEIC problem.

HEIC stands for High Efficiency Image Container. It is the file format Apple introduced in iOS 11 (2017) as the default format for photos taken on iPhone and iPad. The image coding standard inside HEIC is called HEIF (High Efficiency Image Format), developed by the Moving Picture Experts Group — the same organization behind MP4 video.

When you take a photo on a modern iPhone, it is saved as a .heic file unless you have specifically changed your camera settings.

Why Does Apple Use HEIC?

The answer is simple: HEIC photos are roughly half the file size of equivalent JPG photos at the same or better visual quality.

A photo that would be 4MB as a JPG might be 1.8MB as a HEIC. Multiply that by thousands of photos and the storage savings become significant — especially on iPhones with fixed storage.

HEIC also supports features that JPG does not:

• Live Photos (the short video clip paired with each iPhone photo)
• Image sequences (multiple frames in a single file)
• 16-bit color depth (vs. 8-bit in JPG)
• Non-destructive editing metadata

For Apple users staying within the Apple ecosystem, HEIC is superior in almost every way.

The Problem: HEIC Does Not Open Everywhere

The efficiency advantage of HEIC comes with a major compatibility problem. Because HEIC is a newer format controlled by Apple, support outside the Apple ecosystem is inconsistent:

• Windows 10/11: Does not open HEIC by default. Requires a paid codec from the Microsoft Store (or the free workaround via the HEIF Image Extensions app).
• Android: Most Android devices and apps cannot open HEIC files.
• Web browsers: Chrome, Firefox, and most browsers do not support HEIC for display.
• Social media and web services: Instagram, Facebook, most e-commerce platforms, and web forms reject HEIC uploads.
• Photo editing software: Older versions of Photoshop, Lightroom, and other tools do not support HEIC.

In practice, HEIC is a format that works perfectly inside the Apple world and causes frustration everywhere else.

When to Keep HEIC vs. When to Convert to JPG

Keep HEIC when:

• You are staying within Apple devices (iPhone, iPad, Mac)
• You are backing up photos to iCloud (which handles HEIC natively)
• Storage space is a priority and you never need to share outside Apple ecosystem

Convert to JPG when:

• You need to share photos with Windows or Android users
• You want to upload photos to a website, social media, or e-commerce store
• You are sending photos to someone else and do not know their setup
• You want to edit photos in software that may not support HEIC

The general rule: HEIC for personal storage on Apple devices, JPG for sharing.

How to Convert HEIC to JPG Without Installing Software

The easiest way to convert HEIC to JPG is directly in your browser — no software download, no app install, no account required.

Step 1: Open the PicTools HEIC to JPG converter.

Step 2: Drag and drop your HEIC file, or click to select it from your device. You can convert multiple files at once.

Step 3: The conversion happens instantly in your browser. Click Download to save the JPG file.

Your photo stays on your device throughout the entire process — nothing is sent to any server. The converted JPG will look identical to the HEIC original at standard viewing sizes.

This works on any device with a modern browser: Windows, Mac, Linux, Android, or another iPhone.
