Compressing Images In Paint 3D: A Step-By-Step Guide

how to reduce image file size in paint 3d

Paint 3D is a simple and convenient image editing tool available on Windows computers. While it is a great choice for resizing images, it does not support image compression. This means that increasing the size of an image in Paint 3D may result in a blurry or pixelated look. To reduce the file size of an image in Paint 3D, you can open the image in the app, adjust the dimensions by percentage or pixel, and then save the image.

Characteristics Values

Image Size 2448 × 3264 pixels
New Image Size 71 × 95 pixels
Image Quality May become blurry or pixelated
Lock Aspect Ratio Checked to avoid distortion
Resize Image with Canvas Checked to resize image when canvas size is changed
Cropping Cut rectangles, squares or circles

Opening and resizing images in Paint 3D

To open and resize images in Paint 3D, follow these steps:

  • Open the Paint 3D app on your PC.
  • Open the image you want to resize by navigating to Menu > Open, then finding and selecting the image. Alternatively, you can right-click on the image and select "Edit with Paint 3D" from the context menu.
  • Once the image is open in Paint 3D, click on the Canvas button or tab at the top.
  • Check or uncheck the following options to maintain the aspect ratio and prevent distortion:
  • Lock Aspect Ratio: This ensures that the image is logically resized if you edit either the width or height, preventing it from becoming distorted or stretched.
  • Resize Image with Canvas: With this option enabled, the image will be resized when you change the canvas size.
  • Under the Resize Canvas section, you can adjust the width and height of the canvas. You can choose to change the dimensions by percentage or pixel.
  • Enter your desired dimensions. If you are working with specific size constraints, such as a maximum width or height, ensure that you do not exceed those values.
  • Finally, save your image by clicking on the Menu button and selecting "Save" or using the Ctrl+S shortcut.

It is important to note that increasing the size of an image in Paint 3D may result in a blurry or pixelated appearance. If you need to significantly increase the size of an image, consider using alternative tools or methods, such as AI upscaling, to maintain better image quality.

Changing dimensions by percentage or pixel

To change the dimensions of an image in Paint 3D, you must first open the Paint 3D app and open the image file. Then, switch to the Canvas tab, where you will find a drop-down menu. From this menu, you can choose to change the dimensions by percentage or pixel.

If you want to change the image size by percentage, make sure to check the Lock aspect ratio box. This will automatically adjust the width when you change the height and vice versa, preventing the image from becoming distorted or stretched.

If you want to change the image size by pixels, enter the desired height and width under Height and Width, respectively. The numbers are connected, so the ratio of width to height stays the same. If one exceeds your desired maximum size, switch to that dimension and enter the maximum value there.

After you have made your changes, save the image by selecting Menu > Save or using the Ctrl+S shortcut key.

Note that increasing the size of an image in Paint 3D may result in a blurry or pixelated image. If you are looking to significantly increase the size of an image, consider using alternative software or tools.

Saving resized images

To save a resized image in Paint 3D, you can follow these steps:

  • Open the Paint 3D app on your PC and open the image you want to resize.
  • Click on the Canvas button at the top of the screen.
  • Check the "Lock aspect ratio" box to ensure the image isn't distorted when you change the dimensions.
  • Decide whether you want to change the dimensions by percentage or pixel.
  • Enter your desired dimensions.
  • Click the Menu button and select "Save as".
  • Choose "Image" as the file format.
  • Select a location to save the file.
  • Choose "2D-JPEG" from the "Save as type" options.
  • Click the "Save" button.

Now, you can compare the size of the new file with the old one. It is important to note that increasing the size of an image in Paint 3D may result in a blurry or pixelated image. If you want to avoid this, you can use AI to "upscale" your photos instead.

Additionally, when saving resized images, it is recommended to save in the PNG format instead of JPG, as Paint uses very aggressive compression when saving as JPG, which can lead to a loss in image quality.

Using the Canvas options

To resize an image in Paint 3D, you need to open the image in the Paint 3D app. Once the image is opened, switch to the Canvas tab. Here, you will find a drop-down menu that allows you to choose between changing the dimension by percentage or pixel. Select your preferred method and set the resolution accordingly.

Under the "Resize Canvas" section, you will find the width and height of the current canvas. You can choose to lock the aspect ratio, which will automatically adjust the width or height if you edit one of the dimensions, preventing the image from becoming distorted. You can also choose to resize the image with the canvas, which will resize the image when you change the canvas size. It is recommended to keep both options checked for a proper resize.

If you want to focus your image before resizing, you can crop it into different shapes such as rectangles, squares, or circles. Check the "Lock aspect ratio" option under "Resize canvas" to ensure the image is not distorted. Select "Pixels" under "Resize canvas" and enter the maximum height or width. The width and height are connected, so changing one will automatically adjust the other.

After resizing, press Ctrl+S to save the file. You can also go to File > Save as and save the image in your preferred format, such as PNG or JPEG.

Avoiding image distortion

To avoid image distortion when resizing an image in Paint 3D, follow these steps:

Firstly, open the Paint 3D app on your PC and open the image you want to resize. You can do this by navigating to Menu > Open and selecting the image.

Next, click on the Canvas button at the top of the screen. Ensure that the Lock aspect ratio option is checked. This maintains the width-to-height ratio, preventing distortion. If you change the height or width, the other value will automatically adjust to maintain the correct ratio.

If you need to change the original aspect ratio, you may need to crop your image. You can do this by selecting the Crop tool in Paint 3D and choosing the area you want to keep.

After resizing and cropping, click on the Menu button and select Save. You can now compare the size of the new file with the old one.

It is important to note that simply saving a copy of the file in Paint or Paint 3D may reduce the file size, but this method is not suitable for images containing text, as the reduction may not be significant.
