How to Resize an Image Free and Online

Are you seeking to enhance minute details in a photograph? Do you require a larger-than-life image for a specific purpose? Whether it's for printing, digital media, or personal projects, resizing images accurately is paramount.

In this guide, we'll explore the art of resizing images effectively using AI-powered tools AI Image Enlarger. Additionally, we'll delve into specifications for common image sizes and techniques to amplify image dimensions without compromising quality.

1. What Is the Best Image Size?

To answer the question: it depends on what you’re using the photo for.

If you remember, pixels are tiny colored dots that form images. The higher your image's pixel density or resolution, the more detailed it is. With a smaller resolution, your image becomes blurry or pixelated.

If you’re printing an image, you want it to be at the right size. This should be at 300 dots per inch (DPI) at 100% size. Also, 300 DPI is the industry standard for quality photographs.

In the internet era, web images have much lower resolutions. If you’ve noticed, the images you download online often have 72 DPI. This is because computer monitors from the 1980s only had resolutions of 72 DPI.

The truth is the resolution of an image doesn’t have any connection to how you view the image on your screen. However, there is a huge difference between 72-DPI and 300-DPI resolution images on paper. In actuality, DPI is a guide for printers.

When you print an image, consider how large the print will be and the type of printer you’ll use. Use 200-225 DPI for laser printing, 267-300 DPI for commercial offset press, and 360 DPI for photo stylus inkjet. Also, a larger print needs a higher resolution.

It’s worth noting that prints will often need higher resolutions. If you’re building a website, it’ll be smart to use high-resolution images too. If need be, you can always enlarge an image.

2. How Resizing Photos Affect Them

Changing the dimensions of a photo often leads to a loss of quality, especially when you’re enlarging it. You won’t lose quality when you change the picture size to smaller unless you enlarge it back to a larger image again.

As you know, the pixels that form the image are already fixed to a specific location to create the image. When you enlarge the image, the pixels remain in the same places, so the image stays the same. The problem with enlarging images is you only end up enlarging the pixels that form them.

This is what creates the pixelated look on enlarged photos. Opening, editing, and then saving JPEG images also are cause for quality loss. This is why some people get frustrated when their images don’t look as good on paper after they edit them.

This is why you can get a smaller image of the mind-blowing 81-megapixel moon photo by Andrew McCarthy. However, you can’t get the same image details after you save it in a smaller resolution. The secret to having no regrets when resizing images is to edit a copy rather than the original image.

4. Tips on Resizing Images

If you’re resizing an image for your website, ensure it’s already in the correct dimensions. For example, a banner image is almost always wider than it is taller. If you don’t want the image to stretch out sideways or get cropped, ensure they’re already in the right dimensions.

If you’re one of the 81% of Americans who use smartphones, you might have also tried to get some of the photos you took from your phone printed.
