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
PNG (Portable Network Graphics) uses lossless compression and supports transparency. Ideal for logos and screenshots.
Pros
- ✓ Lossless compression
- ✓ Alpha transparency
- ✓ Great for sharp edges
Cons
- ✗ Larger file sizes
- ✗ Inefficient for photos
When to Convert JPEG XL to PNG
Convert JPEG XL to PNG as a fallback for apps that don’t support JXL. Good for editing and sharing.

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

PNG Technical Specifications
Technical details
PNG is a lossless raster format that preserves pixel data exactly. It supports alpha transparency, which makes it a common choice for logos and UI assets.
Good for
- Logos/icons: Assets that need transparency- Screenshots: Crisp text and line art
Notes
- Photos: Files can be large (WebP/JPEG may be a better fit)- Quality setting: Since PNG is lossless, “quality” controls may have little or no effect

Confirm output
Default is PNG. 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 is JPEG XL?
JPEG XL is a next-gen format by the JPEG Committee, supporting both lossless and lossy modes with high compression efficiency. Browser support is still limited.
Does converting to PNG cause quality loss?
No. PNG is lossless, so no additional quality loss occurs during conversion.
Which software can open JXL files?
GIMP 2.99+, darktable, and some ImageMagick builds support it, but most mainstream editors don't yet.
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.
