Resizing Photographs

There are websites online that allow you to resize your photos for free such as imageresize.org and resizeimage.net. There are many reasons to resize an image; perhaps for uploading to social media, emailing to friend(s) or family, or for submitting to the clubs slideshow. Why would you want to resize an image? Your camera is a very advanced tool and it contains millions of pixels. This is good if you want to print your images, but what if you want to share those photographs online? Many websites won’t even let you upload high resolution images, while others like Facebook will down-size them for you, automatically lowering the resolution and quality of those photographs. Because this automated photo reduction process is often not optimized for best quality, it can make your resized photo appear soft and might even result in loss of colors. To prevent that, it is always a good idea to properly resize your images before you use them online. This way, you are in full control of how your photo should look.

How do you resize an image in Lightroom?

Step 1 go to File-> Export or press CTRL+SHIFT+E on your keyboard. The export window will come up

Step 2 Start out from “Export Location” and start out by choosing “Specific folder” from the drop-down. Next, click the “Choose” button and select a folder on your computer where you want the exported files to go. I set mine to “Lightroom Export” but you can choose whatever you want. Some people export to their Desktop and then check “Put in Subfolder” and type a different name every time they export. Whatever works for you. For “Existing Files”, I have set mine to “Ask what to do”, so that the system asks me what to do if a file is already present in my export folder

Step 3 Under “Image Sizing”, make sure to check “Resize to Fit” – this is what will actually resize the image to a smaller version for the web. I usually set mine to “Long Edge”, which limits the width or height of the image (depending on whether it is horizontal or vertical) to a certain value. That value you set right under, in the first input field. I typically use “1024” pixels, which is a good size for the web, but it is up to you if you want to go smaller or slightly larger. NOTE: The part that many people seem to be confused about, is “Resolution” under “Image Sizing”. That setting has absolutely no meaning when exporting your photos for the web. You can set it to any number you want, 1 being the smallest and 65000 being the highest numbers you can use. Whatever number you type in, Lightroom will simply write that number into the file as a reference for printing purposes. If anybody decides to print your image, their printer will most likely default to this resolution / DPI setting. But it really doesn’t matter, because DPI can be changed at the time of printing anyway. I leave mine at 72 pixels per inch.

Step 4 If you have a watermark you want to use, pick the right one under “Watermarking”. If you want to find out how to add a watermark in Lightroom, see our how to watermark a photo in Lightroom page. That's it! You're done. The good news is, once you set the settings in this window, Lightroom will always remember them, so you can reuse the settings without having to modify them each time.
