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
JPEG (Joint Photographic Experts Group) is the most widely used image format, ideal for photographs and images with gradients.
Pros
- ✓ Universal compatibility
- ✓ Adjustable compression
- ✓ Great for photos
Cons
- ✗ Lossy compression degrades quality
- ✗ No transparency support
When to Convert JPEG XL to JPEG
Convert JPEG XL to JPEG when you need maximum compatibility for sharing and uploads.

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

JPEG Technical Specifications
Technical details
JPEG is a lossy format optimized for photos. Lower quality settings reduce file size, but can introduce artifacts around edges and text.
Good for
- Photos: Natural images with gradients- Sharing: Maximum compatibility
Notes
- Re-encoding: Repeated saves accumulate artifacts (use PNG for editing intermediates)- Transparency: Not supported

How to Use
Add files
Drop or click to select your JPEG XL files (multiple supported)
Confirm output
Default is JPEG. You can change to another supported output format if needed.
Adjust options
Set quality, resize, and metadata options only if you need them.
Convert & download
Download each file, or download everything as a ZIP for batch outputs.
FAQ
What happens to quality in JXL to JPEG conversion?
Re-encoding to a lossy format causes some degradation. Quality 90+ keeps it at a practical, acceptable level.
Why hasn't JPEG XL gained widespread adoption?
Chrome dropping support was a major factor.While technically superior, WebP and AVIF gained adoption earlier.
Is metadata preserved?
With the "Keep Exif" option ON, metadata like capture date and camera info is carried over.
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.
What happens to transparency?
JPEG doesn’t support transparency, so transparent areas will be flattened to a background. If you need transparency, choose PNG/WebP/AVIF/JXL instead.
Why do colors sometimes shift after conversion?
Differences in decoding/encoding and color handling can cause small shifts. For critical images, compare the output against the original.
