HEIC to JPEG XL

Why convert HEIC to JPEG XL?

The main difference: HEIC is a lossy format, while JPEG XL is a lossy or lossless format.

Transparent areas stay transparent

HEIC and JPEG XL both handle transparency, so anything see-through in the original is still see-through after conversion.

Lighter images for your website

At the same visual quality, JPEG XL files are noticeably smaller than JPG or PNG. Lighter images mean faster pages, better Core Web Vitals and a small boost for SEO.

What is an HEIC file?

HEIC (High Efficiency Image Container) is the photo format iPhones and iPads have used by default since iOS 11. It's Apple's flavor of the HEIF standard, compressed with the same HEVC technology used for 4K video.

A HEIC photo takes about half the space of a JPG at the same quality and can store extras like Live Photo frames and depth data. The catch is compatibility: Windows, many Android apps and most upload forms can't open it.

How to open an HEIC file

iPhone, iPad and Mac open HEIC natively. On Windows 10 or 11, install the free HEIF Image Extensions (and, on some PCs, the HEVC Video Extensions) from the Microsoft Store. Recent Android phones can view HEIC in their gallery. Anywhere else, convert it to JPG.

What is a JPEG XL file?

JPEG XL is a next-generation image format standardized in 2022 as a successor to JPG. It compresses better than JPG and WebP, supports transparency, HDR and animation, and can losslessly repack existing JPGs about 20% smaller.

Adoption is growing - Apple supports it across iPhone, iPad and Mac, and some cameras and photo apps can save it - but many browsers and programs can't open it yet.

How to open a JPEG XL file

Safari 17+, macOS Sonoma and iOS 17 and later open JPEG XL. Photoshop, GIMP, Affinity Photo and darktable support it. On Windows, and in Chrome, convert it to JPG or PNG to view it.

Extension: .jxl
Compression: Lossy or lossless
Transparency: Yes
Best for: High-quality photos in small files
