HEIC vs JPEG: Why Your iPhone Photos Need Converting and How to Do It

If you own an iPhone, your photos are probably saved in HEIC format by default. Apple adopted HEIC (High Efficiency Image Container) starting with iOS 11 as a replacement for the aging JPEG standard. HEIC offers better compression and smaller file sizes, but it comes with a major drawback: compatibility. Windows, Android, and many web services struggle to open HEIC files natively. This guide explains the differences between HEIC and JPEG, why you might need to convert, and how to do it for free in your browser.

HEIC vs JPEG: Key Differences

Why Convert HEIC to JPEG?

Despite HEIC being technically superior, JPEG remains the most widely supported image format in the world. Every device, operating system, and web browser can display JPEG images. Here are the main reasons to convert HEIC to JPEG:

Cross-Platform Compatibility

When you share HEIC photos with friends and family who use Windows PCs or Android phones, they may not be able to open them. While Windows 10 and 11 can handle HEIC with additional codec installations, many users do not have these installed. Converting to JPEG ensures everyone can view your photos without hassle.

Web Upload Compatibility

Many websites, including social media platforms, e-commerce sites, and online forms, expect JPEG uploads. While some sites accept HEIC and convert it server-side, others reject it outright. Converting to JPEG before uploading eliminates compatibility headaches.

Printing and Editing

Most photo printing services and image editing software work best with JPEG files. HEIC support in third-party software is inconsistent. Converting to JPEG before printing or editing ensures a smooth workflow.

Convert HEIC on Any Device

Converting HEIC to JPEG does not require expensive software. Our free online Image Converter tool runs entirely in your browser. Here is how it works: Upload your HEIC file, select JPEG as the output format, and click convert. The conversion happens locally on your device using WebAssembly, so your photos never leave your computer. You can convert single files or batch process multiple images at once. The tool also supports converting back from JPEG to HEIC if you want to save space on your Apple devices.

Frequently Asked Questions

Is HEIC better quality than JPEG?

At the same file size, HEIC offers better image quality than JPEG because it uses the more modern HEVC (H.265) compression algorithm. HEIC files can be up to 50% smaller than JPEG files while maintaining equivalent visual quality. At maximum quality settings, the difference is less noticeable, but HEIC still produces smaller files.

Does converting HEIC to JPEG lose quality?

Any conversion between lossy formats results in some quality loss due to re-compression. To minimize this, use high quality settings (90-100%) when converting. If you need to preserve the original quality, consider converting to PNG instead, which is lossless. Our tools use optimized encoding to minimize quality degradation during conversion.

Can I change my iPhone camera settings to shoot in JPEG instead of HEIC?

Yes. On your iPhone, go to Settings > Camera > Formats and select 'Most Compatible' instead of 'High Efficiency.' This will save photos as JPEG instead of HEIC. However, this also affects video recording (it switches from HEVC to H.264, producing larger files). Many users prefer to keep High Efficiency for storage and convert select photos as needed.
