By | 14/11/2022

If y’all like sharing your photographs online, whether on Facebook or on your own web log, you should learn how to properly resize your images in Lightroom. While your camera tin take very high-resolution photographs, you might sometimes need to downwardly-size or “downward-sample” those images, non only because most websites won’t accept large images, but also because making those images smaller might actually make them look better, if done correctly. In other cases, yous might need to upwardly-size your image resolution, say for printing purposes. In this quick tutorial, I volition show you the proper way to resize images in both Lightroom Archetype CC and Lightroom CC.

A separate article on how to do this in Photoshop can be found in my “how to properly resize images in Photoshop” commodity. I apply the below method when exporting images out of Lightroom. You tin utilize this technique to whatever photograph – whether information technology is a portrait or a sweeping landscape.

When I wrote about the benefits of a high-resolution sensor, I used the give-and-take “down-sampling” when talking virtually reducing noise and increasing sharpness in high-resolution images. While resizing generally refers to increasing or decreasing image resolution, downwardly-sampling only applies to image reduction.

When an epitome needs to be increased in resolution, the up-sizing process can exist referred to every bit “upscaling” or “upsampling” as well, although these terms aren’t used equally often.

Why Resize Images?

Why would you want to resize an paradigm? Your camera is a very advanced tool and information technology contains millions of pixels. This is skillful if you want to impress your images, but what if you want to share those photographs online? Many websites won’t fifty-fifty 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. Considering this automatic photoreduction process is often not optimized for the best quality, it can make your resized photo appear soft and might even upshot in a loss of colors (when using lossy JPEG compression). To forbid that, it is always a expert idea to properly resize your images earlier y’all use them online. This way, you are in full control of how your photograph looks.

Lightroom Image Resizing Workflow

Lightroom profoundly simplifies the image resizing process. Here is my simplified workflow process:

  1. Import images into Lightroom
  2. Make necessary adjustments to the image I want to resize
  3. Apply sharpening to the full-sized image via the Detail Sub-Module
  4. Export the prototype in sRGB color profile with specific sharpening settings

I employ the above process most of the time and resort to my much more complicated Photoshop resizing process just when working on select images that I want to showcase.

Lightroom Classic CC Image Resizing Process

  1. Select an image or multiple images you lot want to export out of Lightroom Classic CC, then either go to File->Export or press CTRL+SHIFT+East (CMD+SHIFT+Due east on Mac) on your keyboard. The export window will come up up that looks similar this:

    Lightroom Classic CC Export File

    Let’s me go over each section.

  2. Start out from “Export Location” and choose “Specific binder” from the drib-down. Next, click the “Choose” button and select a folder on your computer where yous desire the exported files to go. I set mine to a folder called “Lightroom Export”, but you can choose whatever you lot want. Some people consign to their Desktop and so check “Put in Subfolder” and type a unlike name every time they export. Any works for you. For “Existing Files”, I have set up mine to “Enquire what to do”, so that the system asks me what to do if a file is already present in my consign binder.
  3. Under “File Naming”, if yous check “Rename To”, your exported files will be renamed to something dissimilar. I usually rename my files during the import process and I don’t touch this setting. This way, the file names I have in my organization lucifer the export file names. If I need to re-excerpt an epitome for whatsoever reason, I will know which one I will demand. “Extension” does non affair – I set mine to “Lowercase”.
  4. The adjacent section is very of import. This is where you lot manage the file quality and set up some important parameters:

    Lightroom Classic CC Export File Settings

    When exporting images for the web, you should e’er choose “JPEG” equally the file format. Right next to it there is a “Quality” slider. I take seen some people slide it all the way to the right, thinking that it will preserve the best quality. Well, it does, but it also results in humongous image sizes! I typically have gear up mine betwixt 65 and 84. On rare occasions when I need to impress I might selection a higher value, simply never for the web. In case you are wondering how this value impacts the image size and quality, check out my commodity “JPEG compression levels for Photoshop and Lightroom“. Basically, these percentages work in ranges, so if you set information technology to 77% or 84%, the resulting file size and quality will be identical.

    Next, set “Color Infinite” to sRGB – that’southward what most devices on the Internet are able to come across properly. Go out “Limit File Size To” unchecked.

  5. Nether “Prototype Sizing”, brand sure to check “Resize to Fit” – this is what actually resizes the image to a smaller version for the web. I ordinarily set up mine to “Long Edge”, which limits the width or peak of the epitome (depending on whether it is horizontal or vertical) to a certain value. That value y’all ready right nether, in the first input field. I typically use “2048” pixels, which is a skilful size for the spider web, but it is up to you if you want to go smaller or larger. Don’t employ a high number here, because it will result in a huge file; plus, nigh websites won’t allow you to upload huge images anyway.

    The part that many people seem to be confused most, is “Resolution”. That setting has absolutely no meaning when exporting your photos for the spider web. You can set information technology to any number you want, 1 being the smallest. 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 information technology really doesn’t matter, considering DPI can be changed at the time of printing anyway. I leave mine at 72 pixels per inch, which is the default.

  6. The adjacent “Output Sharpening” department is very of import. This is where you set the amount of additional sharpening Lightroom should apply to images
    they are exported. If you have already applied sharpening in Lightroom’s Develop module, continue in mind that exporting your image at 100% resolution (without resizing) with the “Sharpen For” setting checked will issue in boosted sharpening applied to your image.

    Lightroom Classic CC Output Sharpening

    In this case, since you are reducing the resolution of the epitome, your Lightroom sharpening settings don’t really matter. When exporting landscape images, I typically set my “Output Sharpening” to “Screen” and I choose “Loftier” for Amount. For portraiture, I limit the amount to “Standard”.

  7. The final three sections are called “Metadata”, “Watermarking” and “Post-Processing”:

    Lightroom Classic Export Metadata Watermarking Post-Processing

    When exporting images for the spider web, it might be a good idea to limit the corporeality of metadata that gets extracted with your paradigm, so that sensitive data such as your photographic camera settings, Lightroom adjustments and your GPS location are excluded. My recommendation would be to merely include your copyright and contact information, while everything else is stripped out. If your intention is to get out some metadata / EXIF information for your viewers, and so see my “EXIF information” commodity – I show how to selectively strip EXIF information in that article.

  8. If yous have a watermark you desire to utilize, pick the right one nether “Watermarking”. If yous want to find out how to add together a watermark in Lightroom, see my “how to watermark a photograph in Lightroom” article.
  9. Lastly, leave “Practise nothing” under “Post-Processing” -> “After Export”.

In one case y’all are done, just click the “Consign” button at the very bottom of the window and the paradigm(s) will beginning exporting.

In one case you fix the settings in this window, Lightroom volition e’er remember them, so you can reuse the settings without having to modify them each fourth dimension.

Lightroom CC Image Resizing Process

If yous use the cloud version of Lightroom chosen “Lightroom CC” on your computer or your mobile device, the image resizing process is going to be different.

  1. Select an prototype or multiple images y’all want to export out of Lightroom CC, then either go to File->Export or press SHIFT+E on your keyboard. The export window will come up upward that looks like this:

    Lightroom CC Export Window

    Equally yous tin can see, the export window looks very different from the one in Lightroom Classic CC. The window is much more simplified and you only have a few settings to cull from.

  2. On the right side, you volition come across a “Preset” drop-downward with uncomplicated presets that set item consign sizes like “Export JPG (Small)”, “Export JPG (Large)” and “Export Original”. Don’t worry well-nigh these presets, since they don’t show the exact resolution and might change over time. Instead, get through each setting individually.
  3. Under “File Type”, make certain to select “JPG”:

    Lightroom CC Export Settings

    Set “Dimensions” to “Custom”, which will reveal an additional setting below where yous can enter the Long Side of the image. I set mine to 2048 pixels. Set “Quality” to something like 80%, but feel gratuitous to change this to a different setting, depending on your requirements. For spider web use, 80% is plenty, but if you need to print an image, I would recommend setting information technology to 100%. Get out “Include Watermark” unchecked, unless y’all want to add your watermark to the exported epitome(s).

  4. Click the “More Options” drop-down to reveal more than settings. To exclude all the camera and Lightroom settings, equally well as your GPS location, make sure to select “Copyright Just”. Nether “File Naming”, ready it to “Original” to preserve the original file proper noun:

    Lightroom CC More Options

    The near important setting hither is “Output Sharpening”. To brand certain that your image is properly sharpened, make sure to set “Output Sharpening” to “Screen”, with the corporeality set to “Loftier”. If y’all detect the exported image looking too precipitous for your gustatory modality, you tin can lower it here.

  5. Lastly, set the “Color Infinite” to “sRGB”.
  6. Click the “Consign Photo(s)” push on the top right of the window to export the selected prototype(s). Lightroom CC will prompt where you lot want these images saved, and so you can cull your export folder.

That’s all there is to it.

Why You Should Never Use Lightroom to Upsample Images

As you lot can see from this article, I only provided data on how to downwardly-sample images in Lightroom. You lot might be wondering why I did not provide any information on image upsampling – the process of increasing image resolution across the original. If yous fix the image resolution larger than what you have in the original file, you will end upwardly with a blurry photo. That’s because Lightroom does not accept any advanced features for proper image upsampling!

For this reason, you should never upsample / upscale images in Lightroom. Instead, utilise software like Adobe Photoshop or other third-political party software that is designed for being able to handle image upsampling.
