JPG to JPEG XL

Why convert JPG to JPEG XL?

The main difference: JPG is a lossy format, while JPEG XL is a lossy or lossless format. JPEG XL can have a transparent background, JPG can't.

Supports transparent backgrounds

JPEG XL can hold a transparent background. Convert your image first, then cut out the background or place it on top of other designs.

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 a JPG file?

JPG (also written JPEG, from the Joint Photographic Experts Group that created it in 1992) is the most widely used photo format in the world. Phones, cameras, websites, email and social networks all handle it.

JPG uses lossy compression: it discards fine detail your eye barely notices, which makes photos 5-10 times smaller than an uncompressed copy. The trade-off is that every re-save loses a little more detail, and it can't store a transparent background.

How to open a JPG file

Every device opens JPG files out of the box: Photos on Windows and Mac, the Photos or Gallery app on iPhone and Android, and any web browser. To edit one, use Photoshop, GIMP, Canva or the free tools on ConvertPixels.

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.
