iPhones have saved photos in HEIC format since iOS 11. The format is more efficient than JPG, but it causes friction the moment you try to share or open photos on Windows, email them to someone, or upload them to a service that expects standard formats.
Most HEIC converters online work by uploading your photos to a server. If those photos contain your family, your home, or anything private, that's a bigger trade-off than it looks. ConvertForge converts HEIC to JPG entirely in your browser — no upload, no account, no data leaving your device. Single-file conversion is included in Free; Pro adds unlimited batch conversion.
Quick answer: open ConvertForge, drop in a .heic or .heif photo, choose JPG, set the quality, and select Convert. The JPG is created and downloaded on your device.
Why iPhones Use HEIC
Apple switched to HEIC (High Efficiency Image Container) as the default photo format because it compresses images roughly 2× better than JPG at the same visual quality. A 4MB JPG photo might be 2MB as HEIC with no visible difference.
The problem is compatibility. Apple uses HEIC as its default photo format, but many Windows installations, websites, and older image editors still need additional support to open it. JPG remains the more widely accepted format for sharing and uploading.
The Problem With Most HEIC Converters
Search for "convert HEIC to JPG" and you'll find dozens of web tools. They all work the same way: you upload your file, their server converts it, you download the result.
For a product photo or a stock image, that's fine. For personal photos — your kids, your home, your ID documents, your medical records — sending them to an unknown server is a privacy risk that most people don't think about until it's too late.
ConvertForge takes a different approach: all conversion happens in your browser, using your device's processing power. Your files never leave your machine.

When You Need to Convert HEIC Files
The most common situations where HEIC causes problems:
Sending photos by email. Many email clients and recipients can't open HEIC attachments. Converting to JPG before sending saves everyone the trouble.
Uploading to websites or forms. Most web forms only accept JPG, PNG, or PDF. If you took a photo with your iPhone and need to attach it to an official form or a service, you need JPG.
Editing in software. Older versions of Photoshop, Lightroom, or other editors may not read HEIC. Converting first lets you open the file in any tool.
Sharing on Windows. Windows 10 and 11 can open HEIC with a codec from the Microsoft Store, but many users don't have it installed. JPG works without any extra setup.
Archiving or backing up. JPG is a safer long-term format if you want to ensure compatibility with future devices and tools.
HEIC vs JPG: What's the Difference?
| HEIC | JPG | |
|---|---|---|
| File size | ~50% smaller at same quality | Larger |
| Compatibility | Apple devices | Universal |
| Color depth | 16-bit | 8-bit |
| Transparency | Yes | No |
| Browser support | Limited | Full |
For storage on an iPhone, HEIC makes sense. For sharing, editing, or archiving, JPG is the safer choice.
