How to Change Pixel Size in Lightroom Mobile: An In-Depth Guide

While Lightroom Mobile is primarily known for its superior photo editing capabilities, it also possesses a robust set of export settings that can be used to control the size and quality of your photos when you're ready to share them with the world. One such setting is the ability to change the pixel dimensions of your photo, effectively resizing it. This guide will take you through the process step by step.

Step-by-Step Guide to Changing Pixel Size in Lightroom Mobile

Step 1: Open Your Photo in Lightroom Mobile

Start by launching the Lightroom Mobile app on your device. If you've not yet imported the photo you want to resize, do so by tapping the blue plus icon at the bottom right of the screen and selecting your photo. Once your photo is imported, tap on it to open it in the editing workspace.

Step 2: Open the Export Menu

Now, you'll want to bring up the export menu. You can do this by tapping the share icon in the upper-right corner of the screen. In the dropdown menu, select 'Export As.'

Step 3: Adjust the Pixel Dimensions

After selecting 'Export As,' a new menu will appear with several options. One of these options is 'Dimensions.'

Tap on 'Dimensions' and you'll see two boxes - one for width and one for height. You can tap on these boxes to type in the specific pixel dimensions you want for your photo. Remember that changing the pixel dimensions will change the size of your photo, so ensure that the dimensions you choose are suitable for how you plan to use the image.

Please note that the aspect ratio (the ratio between the width and height) of your photo will remain the same, to prevent the image from becoming distorted. If you want to change the aspect ratio, you'll have to do so before this step by using the crop tool.

Step 4: Export the Photo

Once you're satisfied with your settings, tap on the checkmark in the upper-right corner to save your changes.

Then, in the 'Export As' menu, tap 'Export' at the bottom. Lightroom Mobile will now export your photo with the new pixel dimensions. The newly exported photo will appear in the photo library on your device.


Lightroom Mobile provides a robust set of tools for not just editing your photos, but also controlling how they're exported and shared. By understanding how to change the pixel dimensions of your photos, you gain more control over how your images appear in different contexts, whether that's on social media, a personal website, or printed out.

Always remember to be mindful of how changing the size of your photo can affect its quality. Reducing the pixel dimensions can make the photo appear pixelated if it's viewed or printed at a large size. Conversely, increasing the pixel dimensions too much can lead to a loss of sharpness. It's all about finding the right balance for each individual photo and its intended use.
