What's the best Lightroom export settings for web?

August 9th, 2012
I've been using Lightroom 4 ever since I got my camera, and while learning how to use Lightroom I came across a video on YouTube which gave me export settings. These settings were fantastic! I LOVED the settings. The file size of the images were just right. They usually ranged from 66kb to 250kb. But the pictures were of great quality. I've never had a problem with the way my pictures came out after exporting. The settings have always stayed the same!

That is, until today. I just got a new Macbook Pro. I'm moving from a Windows PC to a Mac, and I'm loving it. But anyways, I moved my Lightroom catalog and everything, but the export settings didn't stay the same as they were on my PC. So that means I had to find new settings. I've been trying to find the right settings, looking on YouTube videos and searching on the web, trial-and-error. My pictures still aren't coming out like they used too. :(

I mainly use my pictures to post on the web and to send to my phone (by text message). So I like small file sizes. What settings can I use?

You dont like the file size? or the image quality? both?

@agima I don't like anything about the export settings! Ummm.. I just want to hear other people's settings. At first it was making my pictures smaller (visually). And, I don't want my pictures to look smaller, I want them to stay the same size they appear in Lightroom. So then I changed image sizing settings to Long Edge with 1024 px and 75% quality. It made one picture bigger (visually) and it made the picture look really low quality. But I noticed on a different picture, it did fine. Maybe it was just that one picture.

Here is a rule of thumb.

Have quality set to 90% and leave it there and only change it when you want the highest quality. The difference between 90% and 100% is almost un-noticeable but it will reduce your files size.

by setting the quality at 75% will effect the image depending on the image so keep it at 90% or above.

By setting your long edge only you will keep the aspect ration of your image and how it is cropped. I only ever use long edge when resizing.

When you set long edge it will stay at that size on the longest side but if your crop is a 1-1 crop (ie square) then it will have a image size of long edge = short edge.

@agima Ohhh, that makes sense. The picture was a 1-1 crop and I was thinking that that's what it was. I haven't done any other 1-1 cropped pictures, so that would make sense.

But what did you mean when you said you only use long edge when resizing? If I don't use the Image Sizing section, then the picture comes out too big looking and the file size is really big. And also, I'm afraid to keep 90% quality because I prefer file sizes 250 and below. I didn't think 90% quality would do that for me, but I'll try next time and see.

what camera are you shooting with?

What @agima is suggesting is that most of us shoot with a camera that has quite high megapixels... I dont know the number exactly but my 7D has a long edge WAY above 1024. This is more than is generally needed to view an image. So by cutting the image size down, we save space. BUT, what happens if you 1/2 the length but the width stays the same? obviously bad right

So, set the long edge only to be resized 1024 or 768 or whatever you want and it will resize the short edge appropriate to maintain the aspect ratio. Incidentally, I defo agree wtih @agima RE the quality, 90% is the sweet spot that i've found through the past couple of years

@toast Thanks for expanding on my post, I think you made it easier to understand what I was saying.

@emjay8 No problem.
