JXL to WEBP Converter

1. Upload one or more JXL files (up to 50 MB total).
2. Click 'Convert to WebP' — finishes in under 3 seconds per image.
3. Download WebP files individually, or grab all as a ZIP.

WebP is supported by every browser since 2020 — while JXL browser support was removed from Chrome in 2023. Converting JXL to WebP trades 30-50% efficiency for near-universal browser compatibility.

JXL is one of the most efficient image formats ever created, but its browser support collapsed in 2023 when Chrome removed it. WebP has been supported by every major browser since 2020 and is used widely for web delivery. If you're publishing JXL images to the web, WebP is the best alternative: modern, efficient (25-35% smaller than JPG), and universally supported by current browsers.

The converter decodes the JPEG XL image and re-encodes it as WebP using libwebp at 85% quality. WebP's VP8-based compression is less efficient than JXL, so output is 30-50% larger. JXL's alpha channel is preserved as WebP's 8-bit alpha.

• Publishing JXL images to modern websites.
• Serving JXL images to Chrome users (which removed JXL support).
• Uploading JXL assets to CMS platforms that support WebP but not JXL.
• Optimizing images for CDN delivery with automatic WebP handling.
• Reducing JXL file size for web while maintaining broad compatibility.
• Preparing JXL images for e-commerce platforms.
• Serving JXL images with a widely-supported modern format.

WebP output uses 85% quality — visually indistinguishable from the source JXL at normal viewing distances. WebP is 30-50% less efficient than JXL, so the output is larger but still 25-35% smaller than JPG. Transparency is preserved. HDR data from JXL is not preserved (WebP is 8-bit).

• WebP output is 30-50% larger than the source JXL.
• HDR metadata from JXL is not preserved.
• Animated JXL sequences are converted using only the first frame.
• Some very old software (pre-2015) may not support WebP.
• WebP is less efficient than JXL for maximum compression.

• WebP opens natively in every browser since 2020.
• Supported by WordPress 5.8+, Shopify, Squarespace, Wix, Ghost.
• Native import in Photoshop 23+, GIMP 2.10+, Affinity, Figma.
• Works with modern CDNs (Cloudflare, CloudFront, Akamai).
• Ideal for web delivery where JXL support is uncertain.

• WebP is supported by every browser since 2020 — safe for most web projects.
• Keep JXL if your target supports it — it's 30-50% smaller.
• WebP preserves JXL transparency — good for logos and UI.
• For maximum compatibility, serve WebP with JPG fallback.
• Batch-convert up to 50 MB of JXL files at once.

WebP is 30-50% larger than JXL

Expected. JXL is significantly more efficient than WebP. The trade-off is broader browser support.

HDR data is lost in WebP

WebP is 8-bit and doesn't support HDR. For HDR, use AVIF or keep the JXL.

Very old software won't open WebP

Software released before 2015 may not support WebP. Convert to JPG for maximum compatibility.
