Reduce Size of a Photo on Windows [5 Methods]
Large photo files can quickly become a problem on any Windows PC. Whether you are trying to upload images to a website, send them via email, or save storage space, oversized photos can slow things down and even fail to upload due to file size limits. The good news is that Windows offers several built-in and third-party ways to reduce photo size without requiring advanced technical skills.
In this guide, I will tell you five practical methods to reduce the size of a photo on Windows.
Reduce the Size of a Photo on Windows [5 Methods]

There are various methods to reduce the size of a photo on Windows. You can use built-in tools like Photos, Paint, and File Explorer compression, or third-party tools. Open the image, resize its dimensions, adjust quality settings, or compress it into a ZIP file to reduce its overall file size quickly and effectively.
Let’s learn these methods in detail!
Method 1: Reduce Photo Size Using the Photos App
The Photos app in Windows is one of the easiest tools to resize images. It comes pre-installed and provides a quick way to reduce file size by changing dimensions.
Step 1: Open the Image in Photos
Right-click on the photo you want to resize and select Open with Photos. This will launch the default image viewer on your Windows system. Make sure the image loads completely before proceeding to the next step.
Step 2: Access the Resize Option
Click on the three-dot menu located in the top-right corner of the Photos app. From the dropdown menu, choose the Resize image option. This will open a new window where you can adjust the image size.
Step 3: Choose a Size Option
You will see preset options such as small, medium, and large. These options are designed for different use cases like profile pictures, emails, or viewing. You can also select the custom option to manually enter dimensions. Reducing the pixel dimensions directly lowers the file size.
Step 4: Save the Resized Image
After selecting the desired size, click Save resized copy. Choose a location where you want to save the new image. The resized version will have a smaller file size while keeping the original image intact.
Method 2: Reduce Photo Size Using Microsoft Paint
Microsoft Paint is another built-in tool that has been part of Windows for years. It offers a simple resizing feature that helps reduce image size effectively.
Step 1: Open the Image in Paint
Right-click on your photo and select Open with Paint. The image will open in the Paint workspace, where you can edit and resize it.
Step 2: Click on Resize
At the top toolbar, locate and click the Resize button. A small window will appear with resizing options based on percentage or pixels.
Step 3: Adjust Dimensions
Choose either percentage or pixel-based resizing. For beginner, percentage is easier. For example, setting the value to 50 percent will reduce both width and height by half, significantly lowering file size.
Step 4: Save the Image
Click File, then Save As, and choose your preferred format, such as JPEG or PNG. JPEG typically results in smaller file sizes compared to PNG, making it ideal for reducing photo size.
Method 3: Compress Photo Using File Explorer
Windows also allows you to reduce file size using built-in compression through File Explorer. While this does not change the image dimensions, it reduces the storage size by compressing the file.
Step 1: Locate the Image File
Open File Explorer and navigate to the folder containing your image. Make sure you can see the file clearly before proceeding.
Step 2: Right-Click the File
Right-click on the image file and hover over the Send to option. From the submenu, select Compressed zipped folder.
Step 3: Create the Compressed File
Windows will create a new ZIP file in the same folder. This file will have a smaller size compared to the original, making it easier to share or store.
Step 4: Use the Compressed Image
You can now attach the ZIP file to emails or upload it online. The recipient can extract the image easily without losing quality.
Method 4: Reduce Photo Size Using Online Tools
Online tools provide a convenient way to compress images without installing software. These tools often allow you to adjust compression levels and preview results.
Step 1: Open a Browser and Visit an Image Compression Website
Launch your preferred web browser and go to a reliable image compression website. These platforms allow you to upload and compress images directly.
Step 2: Upload the Image
Click on the upload button and select the photo from your computer. The tool will automatically begin processing the image.
Step 3: Adjust Compression Settings
Some tools provide sliders or options to control the compression level. Lower quality settings result in smaller file sizes, but you should balance size and clarity.
Step 4: Download the Compressed Image
Once the process is complete, download the optimized image. Save it to your desired location and use it as needed.
Method 5: Reduce Photo Size Using Third-Party Software
If you frequently work with images, using dedicated software can provide better results and more control. These tools often include batch processing, advanced compression, and format conversion.
This method is suitable for users who need professional-level optimization.
Step 1: Install Image Compression Software
Download and install a trusted image optimization tool such as TinyPng, CompressNow, ImageOptime, etc on your Windows PC.
Step 2: Import Your Photos
Open the software and import the images you want to compress. Many tools allow you to drag and drop files directly into the interface.
Step 3: Adjust Compression Settings
Set the desired compression level, output format, and resolution. You can also choose batch processing if you have multiple images.
Step 4: Export the Optimized Images
Click the export or save button to generate compressed versions of your photos. The new files will have reduced sizes while maintaining acceptable quality.
Faqs
What is the best format to reduce photo size on Windows?
JPEG is generally the best format for reducing file size because it uses compression that significantly lowers storage requirements while maintaining decent quality.
Does resizing a photo reduce its quality?
Yes, resizing can reduce quality, especially if you shrink the image significantly. However, if done carefully, the difference may not be noticeable.
Can I reduce photo size without losing quality?
You can minimize quality loss by using compression tools that optimize images intelligently. However, completely lossless reduction is limited.
Why are my photos so large in size?
Photos are large due to high resolution, detailed color data, and camera settings. Modern devices capture images in very high quality, which increases file size.
Is it safe to use online image compressors?
Yes, as long as you use trusted websites. Avoid uploading sensitive or private images to unknown platforms.
Summary
Reducing the size of a photo on Windows is easier than most people think. With built-in tools like Photos and Paint, you can quickly resize images without installing anything. If you need quick compression without altering dimensions, File Explorer ZIP compression is a handy option. For more flexibility, online tools and third-party software provide advanced features and better control over quality and size.
