WebP to JPEG XL

Why convert WebP to JPEG XL?

WebP and JPEG XL are both lossy or lossless formats. JPEG XL is the usual choice for high-quality photos in small files, archiving JPGs losslessly.

Transparent areas stay transparent

WebP 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 a WebP file?

WebP is an image format Google introduced in 2010 to make websites load faster. It can compress photos lossily like JPG, or graphics losslessly like PNG - usually with 25-35% smaller files - and it supports transparency and animation too.

That's why so many images you save from websites, including Google Images, arrive as .webp files. Browsers love them; older software and many upload forms still don't.

How to open a WebP file

Chrome, Edge, Firefox and Safari display WebP directly - drag the file into a browser window. Windows 10/11 Photos and Paint and Mac Preview (Big Sur and later) open it as well. If an app or website rejects it, convert it to JPG or PNG.

Extension: .webp
Compression: Lossy or lossless
Transparency: Yes
Best for: Fast-loading website images

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
