HEIC vs JPG: Which Should You Use?

What Are HEIC and JPG?

JPG (or JPEG, short for Joint Photographic Experts Group) has been the standard photo format since 1992. It's the format that nearly every camera, website, and application in the world understands. Almost nothing will refuse a JPG file.

HEIC (High-Efficiency Image Container) is Apple's newer photo format, introduced with iOS 11 in 2017. It uses HEVC (H.265) compression — the same algorithm behind 4K video streaming — to store photos more efficiently than JPG. Apple chose HEIC as the default iPhone camera format because it halves the storage requirement without sacrificing visible quality.

Both formats serve the same basic purpose: storing a photograph. Their differences come down to efficiency, compatibility, and feature support.

File Size Comparison

The most compelling advantage of HEIC over JPG is file size. A 12-megapixel photo from an iPhone typically occupies 2–3 MB as HEIC and 4–6 MB as JPG at comparable quality. That's roughly a 50% reduction.

In practical terms, if you take 1,000 photos per year (not unusual for smartphone users), shooting HEIC instead of JPG could save 1–3 GB of storage annually on your device and iCloud account. Over several years, that difference is significant — especially on 64 GB iPhones where storage pressure is felt most acutely.

This size advantage comes from HEIC's more advanced compression algorithm, which is better at identifying and encoding patterns in photographic data. JPG was designed in the early 1990s, when processing power was limited. Modern compression like HEVC makes better use of today's hardware.

Image Quality

Comparing HEIC and JPG quality is more nuanced than it appears. At equivalent file sizes, HEIC consistently produces cleaner images than JPG — less banding, fewer compression artifacts around high-contrast edges, and better preservation of fine detail in skies, shadows, and foliage.

However, at very high JPG quality settings (90%+), the difference becomes difficult or impossible to detect without pixel-level inspection. For most practical use cases — sharing on social media, printing standard sizes, viewing on screens — a high-quality JPG looks identical to HEIC.

Where HEIC's quality advantage becomes visible is in HDR content and wide color (P3 gamut). iPhones capture photos with a wider color range than standard JPG can represent. HEIC preserves this extended color data; converting to JPG clips it to the standard sRGB color space. On HDR-capable displays, this difference can be noticeable in vibrant scenes like sunsets or bright flowers.

Platform and App Compatibility

This is where JPG is the undisputed winner. JPG works everywhere, without exception. HEIC has meaningful gaps:

When to Use HEIC

HEIC is the right choice in these scenarios:

• You're storing photos on an iPhone, iPad, or Mac and don't need to share them outside the Apple ecosystem.
• Storage space is at a premium. On devices with 64 GB or 128 GB of storage, the 50% size savings from HEIC is meaningful.
• You want to preserve Live Photo data, Portrait depth maps, or HDR tone mapping for future editing.
• You use Apple Photos or Lightroom 2020+ as your primary editing app and never export to Windows or older software.

When to Use JPG

JPG is the better choice in these scenarios:

• You're sharing photos with Windows or Android users who may not have HEIC support.
• You're uploading to websites, social media, or web services. Most platforms accept JPG without any conversion.
• You're ordering professional prints. Print labs universally support JPG; HEIC is rarely accepted.
• You're attaching photos to emails. JPG displays inline in Gmail, Outlook, and other clients; HEIC shows as a download attachment.
• You're using older software — any version of Photoshop before CC 2021, older Lightroom, or GIMP without plugins.
• You're uploading to a website or content management system that doesn't process HEIC server-side.

The Recommendation: Shoot HEIC, Share as JPG

The most practical approach for iPhone users is to keep your camera set to HEIC (which is the default) and convert specific photos to JPG only when you need to share them outside Apple's ecosystem.

This gives you the best of both worlds: maximum storage efficiency on your device, and universal compatibility when sharing. Converting HEIC to JPG takes seconds using Converter.Plus — just drag your files into the browser tool and download the converted JPGs. No software to install, no files uploaded to any server.

If you frequently share photos with Windows or Android users, you might also consider switching your iPhone camera to "Most Compatible" mode (Settings → Camera → Formats → Most Compatible). This shoots directly to JPG, eliminating the conversion step — at the cost of roughly twice the storage per photo.
