How to Resize a Photo. Available Settings

Watermarkly has several options that you can make use of if you need to resize photos. Let’s take a closer look at them:

Exact Width

This option allows you to change the width of your image by entering a specific number of pixels. The original aspect ratio of your image will be maintained, so the height will be changed automatically.

Exact Height

This works just like the width option - but for height. Enter the desired height in pixels, and the photo resizer will handle the rest by adjusting the width proportionally to keep your image looking sharp.

Not Larger Than

Here, you will also be able to enter values for both the height and the width. But your resized image won’t have these exact pixel dimensions. This is due to the fact that with this option the original aspect ratio doesn’t change. The pixel dimensions of your resized image will be no larger than the values that you entered. It’s quite a convenient option if you need to resize your image, but you don’t want the original aspect ratio to be changed.

Percentage

What if there are no specific requirements for pixel dimensions and you simply want to make your image smaller or bigger? If that’s the case, this option is for you. Here, you will need to enter a number of percent. By default, your original image is 100%. Thus, if you enter 80%, your image will get smaller by 20%.

Flexible Resizing Tools That Preserve Image Quality

We designed our app to preserve the highest possible quality, no matter how you choose to resize your image. It offers all the tools that can help you optimize photos for the web.

If you need to resize and change the aspect ratio

Choose one of these three options:

  • crop an image
  • generate pixels based on the already existing pixels
  • add white pixels to reach the desired size.

Please note that with the first option, the cropping area is always fixed in the center. You won’t be able to change it. So, to achieve the best result, you’ll need to decide what matters more - preserving only the central part of your image or adding new pixels to keep the entire photo intact.
