 # jxl for lightroom
- Add this tool to lightroom export to create jxl files
+Create JpegXl files from Lightroom with user export
+
+> This project is a proof of concept for a user export plugin for Lightroom.
+
+## Motvation
+
+I want to extend the popularity of the [JpegXl](https://jpegxl.com/) format, hopefully this format will be soon supported by OpenSource Community, Google, Apple and Microsoft.
+
+A Lightroom Plugin would be a better way to create JpegXl files out of Lightroom. But I currently have no resources to learn Lua. But this tool works fine and can be integrated into Lightroom.
+
+## What is Missing?
+
+A Lot, feel free to contribute! Or add issues.
+
+See: https://github.com/dhcgn/jxl-for-lightroom/issues
+
+## Install
+
+> Currently only works on Windows
+
+Just copy the file `jxl-for-lightroom.exe` to some location and add this location to your export profile.
+
+I prefer: `C:\Users\MyUserName\AppData\Roaming\Adobe\Lightroom\Modules\jxl-for-lightroom\jxl-for-lightroom.exe`
+
+1. Go to `File->Exports...`
+2. Create a new Preset with these settings:
+   1. `File Settings` to `PNG` (`JPEG` works too)
+   2. `Post-Processing` 
+      1. `After Export` set to `Open in Other Application...`
+      2. `Application` set to the file `jxl-for-lightroom.exe`
+3. Save the preset
+
+## How does it work?
+
+This project include the executable from the project https://github.com/libjxl/libjxl, which will be extracted at program start.
+Lightroom call this tool with all files to convert, then a webpage is opened in the standard browser.
+On the webpage you can select parameters for the encoding to jpegxl and start the encoding.
