Format comparison
JPEG XL is a newer image format designed to support both lossless and lossy compression modes. Support can vary by browser and toolchain.
Pros
- ✓ Supports both lossless and lossy modes
- ✓ Designed for high compression efficiency across content types
- ✓ Suitable for archiving with metadata when supported
Cons
- ✗ Limited browser support
- ✗ Developing tool ecosystem
WebP is a web-focused image format that often achieves smaller files while keeping good visual quality.
Pros
- ✓ Often smaller for web delivery
- ✓ Transparency support (useful for UI assets)
- ✓ Broad browser support
Cons
- ✗ Some older browsers unsupported
- ✗ Limited editing software support
When to Convert JPEG XL to WebP
Convert JPEG XL to WebP for web delivery. WebP is widely supported and often keeps file sizes manageable.
Technical Format Details
JPEG XL Technical Specifications
Technical details
JPEG XL is designed to support both lossless and lossy compression. It can be attractive for experiments and archiving, but real-world support still varies by browser and app.
Good for
- Testing/archiving: Trying a next-gen format where supported- Fallback conversions: Converting back to PNG/JPEG for compatibility
Notes
- Compatibility: Confirm the recipient platform supports JXL- Publishing: WebP/JPEG/PNG is often the safer default for the web
Reference: JPEG XL (JPEG Committee)
WebP Technical Specifications
Technical details
WebP is a web-focused image format that supports both lossy and lossless modes, and it can store transparency.
Good for
- Web delivery: Balancing file size and visual quality- Transparent assets: Often lighter than PNG in many cases
Notes
- Editing: Support varies across software- Compatibility: Some older environments may not support WebP
Reference: Google Developers: WebP
How to Use

Convert & download
Download each file, or download everything as a ZIP for batch outputs.
FAQ
Which is better, JXL or WebP?
Technically, JXL has better compression and features, but WebP has broader browser support, making it more practical today.
Is transparency preserved?
Yes. If the JXL has transparency data, it's correctly preserved in the WebP output.
How fast is the conversion?
JXL decoding is somewhat heavy, but typical-sized images finish within a few seconds.
Will converting reduce image quality?
It depends on the output format. PNG is lossless, so quality stays the same. Lossy formats like JPEG/WebP/AVIF/JXL can change file size and appearance depending on the quality setting. Always verify with the final output before publishing.
Can I keep Exif metadata?
When "Keep Exif/Metadata" is ON, we try to carry over things like capture time, camera info, and GPS where possible. Some tags may be dropped depending on the input, output format, and browser environment. Turn it OFF if you want to remove location data before sharing.
Can I convert multiple files at once?
Yes. You can select multiple files, convert them in one run, and download each file individually. For multiple outputs, you can also download everything as a ZIP. For very large batches, splitting into smaller runs is more stable.
Are my images uploaded to a server?
No. Conversion runs locally in your browser, and your images are not sent to an external server.
What if conversion fails or is slow?
Some formats (like HEIC/HEIF) depend on browser support. If it fails, try another browser, reduce the number of files, or resize before converting.
