Why do iPhones use HEIC instead of JPEG?

Apple introduced HEIC (High Efficiency Image Container) in iOS 11 as it produces files roughly half the size of JPEG at equivalent visual quality. The downside is that HEIC is not supported by Windows (without additional codecs), older Android devices, or many web platforms.

Does converting HEIC to JPEG reduce quality?

Minimal quality loss at 90%+ settings. HEIC and JPEG use different compression algorithms — the conversion involves decoding the HEIC and re-encoding as JPEG, which may introduce very slight quality differences at the pixel level, imperceptible at 90% quality.

Can I convert multiple HEIC files at once?

Batch HEIC conversion is coming in V2. Currently each file is converted individually.

Will it work on Windows?

Yes — the tool runs in your browser, which handles HEIC decoding on modern versions of Chrome and Safari. Full HEIC decoding via the heic2any library (supporting all browsers including Firefox) is being integrated in V1.1.

What is the difference between HEIC and HEIF?

.heic and .heif are different file extensions for the same High Efficiency Image File format. Both are converted identically by this tool.

Why HEIC photos need conversion

HEIC is Apple's proprietary image format, introduced in iOS 11. While iPhones use it by default because it produces smaller files than JPEG, it creates compatibility problems when sharing photos with non-Apple devices and platforms.

🖥 Windows compatibility

Windows 10 and 11 require a paid HEIC codec from the Microsoft Store to open HEIC files. Without it, HEIC photos appear as blank icons. Converting to JPEG ensures anyone on Windows can open your photos without additional software.

🌐 Web platform support

Most websites, web apps, and online tools do not accept HEIC uploads. E-commerce platforms (Amazon, Etsy, Shopify), social media schedulers, and email clients generally require JPEG or PNG. Converting before upload prevents upload failures.

📷 Older Android devices

Android devices prior to Android 12 cannot open HEIC files natively. Converting to JPEG ensures compatibility when sharing photos with Android contacts.

👔 Professional workflows

Design tools (older versions of Photoshop, Lightroom, Canva), document editors, and professional image processors often require JPEG or PNG input. Converting HEIC to JPEG integrates iPhone photos into professional workflows without compatibility issues.

Frequently asked questions

Why does iOS save photos as HEIC? ▼

Apple uses HEIC because it produces files approximately half the size of JPEG at equivalent visual quality — saving storage space on iPhones. The trade-off is reduced compatibility outside the Apple ecosystem.

How do I stop my iPhone from saving photos as HEIC? ▼

Go to Settings → Camera → Formats → Most Compatible. This switches the camera to save JPEG instead of HEIC. The downside is larger file sizes. Alternatively, continue shooting in HEIC and convert when sharing.

Is there quality loss when converting HEIC to JPEG? ▼

At 90%+ JPEG quality, the difference is imperceptible in normal use. Both are lossy formats, so re-encoding introduces a very small additional quality reduction. For archiving purposes, convert to PNG instead for lossless output.

Can this tool convert HEIC files from any device? ▼

HEIC files from iPhones, iPad, and Mac are all supported. Some newer Android devices and cameras also produce HEIC files — these should convert correctly. The full heic2any library integration in V1.1 will ensure universal HEIC support across all browsers.
