An LRWEBENGINE folder is part of Adobe Photoshop Lightroom, the photo-management and editing application from Adobe. Despite its file-extension-like name, it is a folder rather than a conventional document.
The folder contains the files that define a web gallery engine, including the template resources Lightroom needs to generate a gallery. It works with Lightroom's Web module and is used when generating web galleries.
This format is associated with the Mac version of Adobe Photoshop Lightroom, running on Apple macOS and earlier Mac OS X systems. It is intended for Lightroom's web-gallery feature rather than for direct use as an independent file.
On a Mac, open the .lrwebengine item in Finder to view it as a folder. Its contents are intended to be read by Adobe Photoshop Lightroom, not opened as a normal document.
Install or keep the folder in the Lightroom location where web gallery engines are stored, then use Lightroom's Web module to use the gallery engine. The exact contents should not be edited unless the user understands Lightroom web-gallery templates.
An .lrwebengine folder is not normally converted to another file format. It is a set of Lightroom web-gallery resources, not an image or document.
To create files in a usable format, open the gallery in Adobe Photoshop Lightroom and export or publish the resulting web gallery. This produces the gallery output rather than converting the engine folder itself.
