All you need to do is open the image with Preview, select "Tools" and scroll down to "Adjust size". You can choose resizing parameters from predetermined dimensions or customize both the width and height using pixels or inches.


It's important to keep in mind that opting for higher resolutions will result in a larger file size of the final image. Lower dimensions can be beneficial when sharing images via email or online, as it reduces the time it takes to upload or send them.

What are the common units used for image dimensions?
Image dimensions are typically measured in pixels (px), but other units like inches or centimeters can be used, especially in print media.
What is aspect ratio in resizing?
Aspect ratio is the ratio of an image's width to its height. Maintaining the aspect ratio is crucial to prevent distortion when resizing an image.
What is interpolation in image resizing?
When you resize an image, especially when enlarging it, you are essentially creating new pixels to fill the increased space. Interpolation algorithms determine the color and intensity of these new pixels by considering the values of neighboring pixels in the original image.
What is the difference between upscaling and downscaling?
Upscaling involves increasing the size of an image, while downscaling reduces its size.


Resizing images is an essential skill in the digital era where visuals play a key role in communication. Whether you prefer the convenience of online tools or the power of offline software, these 5 image resizers are sure to enhance your image processing capabilities.

So, choose the one that suits you best and take your image resizing to the next level.
