Compressing Images With Paint: A Step-By-Step Guide

how do i reduce image file size with paint

There are several ways to reduce the file size of an image using Microsoft Paint or Paint 3D. One way is to simply open the image in Paint and save a copy of the file, which will reduce the file size automatically. Another way is to change the image's resolution by opening the image in Paint, clicking on the “Resize and skew option in the Image menu, and selecting a new resolution. You can also change the file size by saving the image as a JPEG file, which will reduce the file size while maintaining its quality. It is recommended to work on a copy of the image rather than the original file.

Characteristics Values
Image Format JPEG
File Size Reduction 21% to 36%

Open the Paint app and your image

To reduce the file size of an image using Paint, you will first need to open the Paint app and your image. You can use the taskbar search box to open the Paint app.

Once the Paint app is open, you can open your image by clicking on the “File” menu and selecting “Open” or by using the Ctrl+O shortcut. You can also use the “Open” option in the “File” menu to select your image. It is recommended that you work on a copy of the original image file, rather than the original itself. To do this, simply right-click on the image, select "Copy", and then right-click on your desktop and select "Paste".

With your image open in Paint, you can now proceed to resize it. Click on the “Image” menu and select the “Resize and Skew” option. From here, you can select a new resolution for your image. You can change the dimensions by percentage or pixel. If you wish to change the image size by a certain percentage, ensure that “Percentage” is selected at the top of the “Resize” window. For example, changing the image's value to 75 will result in it becoming 3/4 of its original size.

If you are working with an image that contains text, you may not find a significant reduction in file size.

Use the 'Resize and skew' option

To reduce the file size of an image using Paint, you can use the "Resize and skew" option. This option is available in the "'Image' menu" of the Paint app, which can be found in the top left part of the window, just before the "Selection" menu.

Once you've opened the "Resize and skew" box, you can change the resolution of your image by increasing or decreasing the dimensions by a percentage or by specifying the exact pixel count. If you want to make your image smaller overall without needing exact pixel dimensions, select "Percentage" and enter a number less than 100. For example, changing the values to 75 will make your image three-quarters of its original size.

If you know the exact pixel count you want for your image, select "Pixels" and enter the desired height and width. You can also enter new values for both the width and height of your image, but if you do so, the original aspect ratio won't be maintained, and your image may end up stretched out or distorted.

Before applying your changes, make sure to check the "Maintain aspect ratio" box to ensure your image doesn't become distorted.

Finally, click "OK" to apply the changes, and then press "Ctrl+S" to save your resized image.

Change the resolution

To change the resolution of an image in Paint and reduce its file size, you can follow these steps:

First, open the Paint application on your computer. You can use the taskbar search box to find and open the Paint app. Once the app is open, you can open your desired image file by pressing the Ctrl+O hotkey or by going to the File menu and selecting the Open option.

After opening the image in Paint, you can access the image resizing options. Click on the Image menu and select the "Resize and skew" option. This will open a window where you can adjust the image's resolution. Make sure that “Percentage” is selected at the top so that your changes are measured in percentages. For example, changing the values to 75 will make the image 3/4 of its original size.

You can also choose to maintain the aspect ratio of the image by checking the "Maintain aspect ratio" box. This will ensure that your image is not distorted when you change its resolution. If you want to change the dimensions by a specific amount, you can uncheck the "Maintain aspect ratio" box and set your desired dimensions by adjusting the height and width separately.

Once you have selected your desired settings, you can enter the new resolution values in the “Horizontal” and “Vertical” text boxes. These values can be entered as a percentage or in pixels, depending on your preference. After entering the new values, click the "OK" button to apply the changes.

Finally, save your resized image by pressing Ctrl+S or by going to the File menu and selecting the "Save" option. Choose a location to save your file and compare the new file size with the old one to see the reduction in size.

Save as a JPEG

To reduce the file size of an image using Paint, you can save it as a JPEG file. Here's how you can do it:

  • Open the Paint application on your computer.
  • Create a copy of the original image file and open it in Paint. This step is optional but recommended to avoid altering the original image.
  • With the image open in Paint, go to the "'File' menu".
  • Click on the "Save As" option.
  • In the "Save as type" dropdown menu, select "JPEG" as the file format.
  • Choose a location to save the file and click "Save."

By following these steps, your image will be saved in JPEG format, which typically results in a smaller file size compared to other image formats. You can then compare the size of the new JPEG file with the original to see the reduction in file size.

Additionally, if you're using Paint 3D, there are a few extra steps you can take to adjust the image size:

  • Open the Paint 3D app and open your image.
  • Switch to the "Canvas" tab.
  • Choose whether you want to change the dimensions by percentage or pixel in the dropdown menu.
  • Set your desired resolution accordingly.
  • Save the file by pressing Ctrl+S or by going to the "'File' menu" and selecting "Save."

Remember that while reducing the image size can decrease the file size, it's important to strike a balance to avoid compromising the image quality.

Compare old and new file sizes

Comparing old and new file sizes is a crucial step in the image compression process. By evaluating the file size before and after compression, you can ensure that you've achieved the desired balance between image quality and file size reduction. Here's a step-by-step guide to help you compare old and new file sizes effectively:

Step 1: Note the Original File Size

Before proceeding with any resizing or compression, it's important to take note of the original file size. Right-click on the image file, select "Properties," and you'll find the file size information under the "Details" tab. Make a note of the file size, as this will serve as your reference point for comparison later on.

Step 2: Resize the Image Using Paint

Open the image in Microsoft Paint. Go to the Resize window, ensuring that "Percentage" is selected. Adjust the percentage to reduce the image size; for example, changing the value to 75% will make the image three-quarters of its original size. Remember to check the "Maintain aspect ratio" box to prevent distortion. Save your changes, and note the new file size by following the same right-click and "Properties" method as before. Compare the new file size to the original, and you should see a reduction in size.

Step 3: Compare the File Sizes

Now, you can directly compare the old and new file sizes. Subtract the new file size from the original file size to find the exact amount of reduction achieved. For example, if your original image was 2 MB and the resized image is 0.5 MB, the reduction in file size is 1.5 MB.

Step 4: Evaluate Image Quality

While reducing file size is important, you also need to ensure that the image quality remains acceptable. Open both the original and resized images side by side and visually inspect them. Look for any signs of blurriness, pixelation, or loss of detail. If the quality degradation is unacceptable, you may need to adjust the compression settings or try a different compression method.

Step 5: Repeat as Necessary

If you're not satisfied with the balance between file size and image quality, repeat the process with different settings. You can try using a different percentage for resizing or explore other image editing software that offers more advanced compression options, such as Adobe Photoshop or Lightroom, which provide both lossy and lossless compression methods.

Remember, the goal is to find the right compromise between file size and image quality. By following these steps, you can effectively compare old and new file sizes, make informed decisions about your compression settings, and achieve the desired outcome for your images.
