Hi there,
I have issues with exportation with Lightroom, here my issue:

My partner has a MacBook Pro, she use Lightroom's, edit the photo + preset and she export everything on her desktop with these stats:

- JPEG , Quality: 100
- Resize to fit: Long Edge, 1 080 Pixels and Resolution: 72 pixels per in
- Sharpen for: Screen and Amount: Standard

Photos export and bang, everything is perfect. Photos are around 2.8-3.2 mb and perfect shape and look.

Now on my side with my iMac 5k retina, same thing, I import, edit, preset and now with the same settings to export.

My photos are 578kb, looks awful and I have no clue what to do.

Any help could be nice.
Thanks

A 1080 pixel long edge image file viewed at 1:1 (100%) view will only fill about 1/5 of your Retina 5K screen width (5180 x 2880). If you're viewing it at a Zoom size larger than that it will look pixelated and "awful."

When you import jpegs and then export jpegs, you are seeing the result of the image being compressed twice. That is the reason for the loss of quality.

For this process, your partner should export tiffs for you to import.

Perfect, How can I make sure that the size and quality are the best?

What do I change in the Long Edge, my 1080 pixels? But will it be the same view on a not retina screen?

-_- Beginner having issues here.

The size in pixels that you choose to export is basically all about the use of the exported image.

1080 - that sounds like Instagram

900 to 1200 - a good size of websites and email

not resized - good for printing

When exporting full-size images, I use a JPG quality setting of 90%, which is good compression at a great visual quality (100% does not buy you anything).

When exporting web-sized images I use a quality setting of 80%.

(There is only 12 different quality levels even though the scale does 1-100.)

Show us a screen capture of one that "looks awful". What software are you using outside of Lightroom where it looks awful?

What zoom level are you using when it "looks awful"? if you are blowing up the 1080 pixel on the long side export to fill up a 5K screen, I would expect it would look awful.

Are you using smart previews and exporting without the original being available?

This is a ''Test'' photo exported with all my settings.
Size: 598kb .

Suppose to be 2.8mb

The image file looks perfectly fine on my display at 1:1 Zoom View (100%) inside LR. JPEG file size is dependent on numerous factors such as image detail, noise, and sharpening amount.

If you want to display the image file so it fills your (and other's) 5K Retina screen you need to increase the Long Edge setting to 5120 pixels.
