How do I get large (8MB+) JPEG files when exporting from lightroom?

I totally get all the reply's here, but I have been exporting at 100% for years always producing files that are about 29mb. All of a sudden all of my exports are 4.6mb. If this is correct ad no problem that's all good but I am so so so curious as to what has changed, either in my setup or with the latest update of Lightroom classic.

This is a cool request! Normally you will be asked to have less Mbs!

Now the trick is: If your picture exports at a quality of 100% and the image size is at 100%, the file you receive is the best possible quality, regardless of its size.

Files with great areas of a single colour (or a single shade of colour) compress very well, files with a lot of noise in (that can be camera noise, but that can be also natural noise) compress less, meaning that they generate a larger file size.

I limit my JPEG files to a max of 3Mb normally. We're telling people that files around 2 Mb are OK for printing purposes. That's our rule of thumb, just to avoid that people send in files of 20kb.

nathalieholland  wrote Hello! Hoping someone may be able to shed some light on this for me please...! I'm editing RAW files using LR, taking them into PS, then saving them back to LR and trying to export in sRBG. I'm not sure where i'm going wrong but my the exported JPEG's only come out at 3-5MB and I need them about double the size! I've checked all the export settings and even tried to export direct from PS but they still end up at only 3-5MB and I really don't know why!! Please can someone help??!! Thanks so much

Why do you need them at 6-10MB, don't you just need them at 100% quality?
