Can Lightroom export photos from the command line using current Develop settings?

I want to serve photos from my Lightroom catalog over a home network web server. Most originals are RAW, but browsers need JPEGs. Ideally, I’d generate JPEGs on demand so I don’t have to maintain a second exported copy of the whole catalog whenever I add or edit photos.

My main requirement is that the exported file should reflect the Develop adjustments already made in Lightroom. Is there any supported way to call Lightroom from the command line to export an individual image as JPEG (or TIFF), or otherwise trigger Lightroom externally for this workflow?

Long story short, NO.

The current stable release of Lightroom does not support command line usage and therefore can not be used from any external tools. Lightroom does provide a SDK for developers but that's mostly for writing plugins, not for utilizing its internal functionality. May be in future versions Adobe will incorporate this feature.

If you want to convert RAW files to JPEG without any human involvement, there are other engines available for this purpose, for example DCRAW which is open source and supports command line usage in linux, mac and windows.

No—Lightroom does not provide a supported command-line export workflow for this. Its SDK is aimed at plugins, not external command-line control of Lightroom’s internal export/develop engine.

So if your goal is to render JPEGs that use Lightroom’s existing Develop settings, Lightroom itself is not a good fit for an on-demand web-server pipeline.

Your practical options are:

  1. Export from Lightroom ahead of time and keep that output updated, or
  2. Use a different RAW processor that supports command-line processing.

Community suggestions included command-line-capable tools such as dcraw or RawTherapee. RawTherapee in particular can apply saved processing profiles from the CLI, which makes it more suitable for automated conversion.

But if the key requirement is specifically “use Lightroom’s edits/settings,” then the answer is still no: Lightroom doesn’t expose that capability via the command line.
