What is HEIC format and why does my iPhone use it?

HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It uses the HEVC (H.265) codec to compress photos to roughly half the size of JPEG while maintaining the same visual quality. This saves significant storage space on your iPhone. However, HEIC is not universally supported — Windows, many web platforms, and older software cannot open HEIC files natively.

Will converting HEIC to JPG reduce image quality?

There is a minimal quality reduction because JPEG uses lossy compression. However, at the default quality setting (92%), the visual difference is virtually undetectable. HEIC files are already compressed, so converting to JPEG at high quality preserves nearly all detail. You can adjust the quality slider to find the right balance between file size and visual fidelity.

Can I convert multiple HEIC photos at once?

Currently, Convert Media processes one image at a time. Upload a HEIC file, convert it to JPG, download the result, then repeat for the next file. Each conversion takes less than a second, so batch converting several photos is still very quick.

Does this work with HEIF files too?

Yes. HEIC and HEIF are closely related — HEIC is technically a specific type of HEIF container. Convert Media supports both .heic and .heif file extensions. Whether your file comes from an iPhone, iPad, or a camera that shoots in HEIF format, it will convert to JPG without issues.

Are my photos uploaded to a server?

No. All conversion happens entirely in your browser. Your HEIC photos are decoded locally using a WebAssembly library, then converted to JPG using the Canvas API. No data leaves your device at any point — the process is completely private and works even offline after the page has loaded.

HEIC to JPG Conversion Guide

Everything you need to know about converting Apple HEIC photos to universally compatible JPG format.

What Is HEIC Format?

HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11 and macOS High Sierra. It uses the HEVC (H.265) codec to compress images, producing files roughly half the size of equivalent JPEGs while maintaining the same visual quality.

While HEIC is excellent for saving storage space on Apple devices, it is not universally supported. Windows applications, many web platforms, older image editors, and some social media sites cannot open HEIC files directly, making conversion to JPG necessary for sharing and compatibility.

HEIC vs JPG Comparison

Feature	HEIC	JPG
Compression	HEVC (H.265)	DCT-based
File Size	~50% smaller	Larger (baseline)
Quality	Excellent	Good to excellent
Compatibility	Apple ecosystem	Universal
Transparency	Supported	Not supported

When to Convert HEIC to JPG

Convert your HEIC photos to JPG when you need to share them on platforms that don't support HEIC, upload to websites or social media, open them in older image editing software, or send them to non-Apple users. JPG is the most widely supported image format — it works everywhere.
