Format comparison
AVIF (AV1 Image File Format) is a modern image format that targets high compression efficiency while preserving quality. Depending on the environment, encoding/decoding can feel heavier than older formats.
Pros
- ✓ Strong compression efficiency
- ✓ Can support HDR / wide color in supported pipelines
- ✓ Transparency support
Cons
- ✗ Slow encoding
- ✗ Limited browser support
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
When to Convert AVIF to JPEG XL
Convert AVIF to JPEG XL when you want to compare behavior across next-gen formats or run compatibility tests.
Technical Format Details
AVIF Technical Specifications
Technical details
AVIF is a modern image format often used for web optimization. It can be very efficient for photos, but performance and support vary across browsers and apps.
Good for
- Web delivery: Smaller files on supported platforms- Photos: Keeping quality while reducing size
Notes
- Performance: Encoding/decoding can feel heavier (split large batches when needed)- Compatibility: Not every environment can open AVIF — keep WebP/JPEG fallbacks if required
Reference: AOM: AVIF Specification
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

Drop or click to select your AVIF files (multiple supported)
Confirm output
Default is JPEG XL. 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's the benefit of converting AVIF to JXL?
JPEG XL offers higher lossless compression efficiency than AVIF, plus HDR and progressive display support -- ideal for archiving.
Can browsers display JXL?
Safari supports it, but Chrome and Firefox don't. JXL is better suited for local storage than web display.
Is there re-encoding quality loss?
Lossy-to-lossy re-encoding causes some degradation. For archival purposes, use high quality settings.
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.
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.
