I don’t want to compress my Jpeg with Ios on LrM

How can I setup the Jpeg compression for export on LrM? I don’t want to use Ios compression because I loose to much quality with small size file

At this time, the ability to change it is not available to the user but it is in the works for a future update.

Hi Rikk, good to hear that Adobe has it in plan, because I fear that the compression percentage is currently under 75%
Have done some tests with Photoshop Express on my iPad and guessed it based on file size.

Thanks a lot for the reply. Glad to hear there will an update soon. And yes, it’s the same size with Photoshop Express.. So no way to get full size Jpeg on Ios for the time being?

In PS Express you can select the compression rate

Yes I know but even at 100% on export with a raw file, I get the same size (around 5Mo).
Maybe there will be full size jpeg on Ps for Ipad pro in few weeks?

Here an interesting test made by Jeffrey Friedl:

After reading this test I am very interested to know the compression factor Adobe LR CC is using.

Lightroom Desktop (formerly known as CC) uses an 80% (Lightroom Classic scale) compression on smaller than full-size. Full size are using 100%.

Thank you Rikk, that is very good to know. Is it the same for LR Mobile on iOS and Android?

Very interesting but the test has been made 9 years ago. A new one should be made because compression factor has certainly evolved since 2010.
Here is a test I’ve just made when you zoom in at 200%. On the left compression quality at 75 and on the right 100%. For Me it’s much sharper on fine detail like hair.
