If you own an iPhone or iPad, your photos are most likely saved in HEIC format rather than the traditional JPG. Apple adopted HEIC as the default image format starting with iOS 11, and while it offers real advantages, it also creates headaches when you try to share photos with non-Apple devices. Here is a clear breakdown of the two formats and when each one makes sense.
What Is HEIC?
HEIC stands for High Efficiency Image Container. It is based on the HEIF (High Efficiency Image Format) standard and uses advanced compression algorithms derived from the HEVC (H.265) video codec. Apple chose HEIC because it delivers noticeably better compression without sacrificing visual quality. In practical terms, a HEIC photo takes up roughly 50% less storage space than an equivalent JPG at the same perceived quality.
What Is JPG?
JPG (also written as JPEG) has been the universal standard for photographs since the early 1990s. It uses lossy compression to reduce file sizes and is supported by virtually every device, browser, application, and operating system in existence. While its compression technology is older and less efficient than HEIC, its compatibility is unmatched.
HEIC vs JPG: Key Differences
- File size: HEIC files are approximately 50% smaller than JPG files at equivalent quality. A 3 MB JPG photo might be only 1.5 MB as a HEIC file.
- Image quality: At the same file size, HEIC preserves more detail and fewer compression artifacts compared to JPG. The newer codec is simply more efficient.
- Compatibility: JPG works everywhere. HEIC is natively supported on Apple devices, recent versions of Windows 10 and 11, and some Android devices, but many web platforms, older apps, and services still do not accept it.
- Transparency: HEIC supports transparency (alpha channel), while JPG does not.
- Color depth: HEIC supports 16-bit color depth, compared to JPG's 8-bit. This means smoother gradients and more accurate colors in HEIC files.
- Editing flexibility: HEIC stores edits non-destructively on Apple devices, so you can revert changes. JPG edits are permanent once saved.
When to Use HEIC
Keep your photos in HEIC if you primarily use Apple devices and want to save storage space. HEIC is ideal for keeping original photos on your iPhone, iPad, or Mac where the format is fully supported. It is also the better choice when you want to preserve the highest possible quality for later editing.
When to Convert to JPG
Convert to JPG when you need to share photos with people using non-Apple devices, upload to websites or platforms that do not accept HEIC, attach images to emails where compatibility is uncertain, or use images in applications that only support standard formats.
How to Convert HEIC to JPG
The fastest way to convert HEIC photos to JPG is with fileGOD's HEIC to JPG converter. Drop your HEIC files in, and the tool converts them to universally compatible JPG format right in your browser. No uploads to any server, no quality loss beyond normal JPG compression, and you can batch convert multiple files at once.
You can also use the universal image converter if you need to convert to formats other than JPG.
