Just about every day I read a comment from a photographer complaining about Facebook making their images look terrible. There are hundreds of websites that have done tests and posted results to show what they feel is the best resolution to post your images to Facebook. Rather than run a bunch of tests I am going to keep things simple and tell you exactly what has worked well for me. Feel free to check out the results on my Facebook Page of images I have posted there. Hopefully this article saves a few of you the grief of sharing beautiful images on Facebook only to have their compression formula ruin them.
I promised to keep it simple. So here you go. When posting to Facebook you have two options.
1. To show the images as large as possible on Facebook, make the long size of your image 2048px.
2. If you would prefer to keep your images looking nicely but in a smaller size make the long side 960px.
There are a number of ways to prep your photos for Facebook. Here are three simple options.
HOW TO RESIZE IN LIGHTROOM FOR FACEBOOK
In the Lightroom Export box. Go to the options under Imaging Sizing. Choose "Resize to Fit" then click the drop down box and choose "Long Edge." Type in 2048 and make sure pixels is selected. Once you have done that, save your settings as a User Preset for exporting images by clicking the "Add" button in the bottom left corner so you can easily use the same settings in the future.
HOW TO RESIZE IN PHOTOSHOP FOR FACEBOOK
In Photoshop after you have finished editing your image, go to File > Automate > Fit Image. When the dialog box pops up type in 2048px (or 960px) in each of the fields. Click OK. Once it finishes resizing I will often run another round of sharpening using the Unsharp Mask. Just as with the Lightroom preset, I would highly encourage you to make this into an "action" so that you can do this with a simple click of a button.
HOW TO RESIZE IN BLOGSTOMP FOR FACEBOOK
The third option is using a program called BlogStomp. It is a popular program to help get 2+ images combined together and resized quickly so they can then be uploaded to your Blog or Facebook. If you choose to use this program, click the drop down on the bottom to choose to "Edit (or create) Your Styles." When the settings box pops up just choose the Image Width to be 2048. Give your new style a name and save it. Then make sure to select your new style from the drop down box before choosing the images you would like to stomp.
I know some people will say that the quality is better when you save and upload your images to Facebook as PNG files. I have tried it and didn't notice a ton of difference. But the key is to make sure to use 2048px or 960px on your pixel dimension. By choosing either of those dimensions Facebook's compression formula should leave your images still looking crisp and clear for all your fans.
I promised to keep it simple. I realize there are quite a few different ways to resize your images and I would love to hear what has been working best for you in the comments.
