Convert JPEG XL locally: lossless JPEG to JXL, batch image to JXL, and JXL export to JPG, PNG, or GIF.
Image2JXL is a local JPEG XL image converter. Everything runs on your device, with no uploads or cloud processing.
What you can do:
1. Convert images to JXL: JPEG, PNG/APNG, GIF, TIFF, BMP, NetPBM (PPM/PNM/PGM/PAM). JPEG can use lossless transcoding.
2. Export JXL to JPEG, PNG, or GIF. JXL files created from lossless JPEG transcoding can be restored to JPEG.
3. Convert batches and folders by drag and drop, with per-file status.
4. Control output folders, save beside the source, ask before saving, and preserve folder structure with Pro.
5. Tune quality, distance, and effort, and preserve EXIF/XMP metadata when the target workflow supports it.
Image2JXL does not provide online compression, cloud processing, or file uploads.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Recent updates:
- Improved source file protection to prevent converted files from overwriting originals or other source files in the batch.
- Fixed an issue where the app could keep retrying after failing to create an output file.
- Improved EXIF metadata preservation and compatibility with older files, and corrected image dimension and orientation metadata in exported files.
- Improved importing large numbers of files and folders, added an import progress indicator, and reduced interface freezes.
- Fixed issues with conversions starting more than once and not running again after changing the output format or save location.
- Added a clear message when an original file cannot be moved to the Trash, while keeping the converted file.
- Fixed messages disappearing too soon and improved accessibility labels for sliders.
- Updated the bundled JPEG XL codec library to libjxl v0.12.0, including upstream security fixes.

- Added pause and resume buttons for more flexible batch conversion control.
- Improved VoiceOver support.
- Improved the UI and interactions.
- Fixed cases where animation could be lost when exporting JXL to GIF/PNG, while preserving frame and loop information.
