Lightroom Desktop incorrectly compresses images when exporting. "Original" export does not preserve the original file, and "Large JPEG" export has significantly reduced quality. Mobile exports work correctly.
Hello Adobe Support,
I am experiencing an issue with Lightroom Desktop when exporting photos, and I would appreciate your assistance.
The problem only occurs in the desktop version of Lightroom. Whenever I export an image using either the Original or Large JPEG export option, the exported file has noticeably reduced quality and does not match the original image.
In addition, every time I export, Lightroom displays the following warning:
"Warning: Some images may not be exported at the size you requested because we couldn't access the full-size original."
This happens even though the original photos should be available.
What is confusing is that the Lightroom mobile app works perfectly. Using the same photos, I can export both Original and Large JPEG versions without any quality loss or unexpected compression. The issue is only present on Lightroom Desktop.
Because of the warning message, I suspect Lightroom Desktop is somehow unable to access the full-resolution originals, even though they are available and the mobile application has no problem exporting them.
Could you please help me determine why Lightroom Desktop cannot access the full-size originals and why it exports lower-quality files instead? I can provide screenshots of the warning message, my export settings, and sample files if needed.
Thank you for your assistance.
Kind regards,
