A Guide to Resizing Photos: Online or with Photoshop (Without Losing Quality)

Editorial team Published on 2/16/2024

Let’s start with the basics: to maintain a professional online presence, it’s crucial to take care of the quality of the photos you use for communication. And by “taking care,” it’s not just about using images with extremely high resolution.

Keep in mind that when it comes to the images you upload online, overly large photos can appear pixelated and blurry (in addition to slowing down page loading and causing SEO optimization issues), just like low-resolution images. For each intended use, the right format, size, and weight are essential.

Today, we will focus on a crucial aspect: how to resize images. Here, you will find:

– A simple guide on resizing photos with Photoshop.

– 3 free online image resizing tools.

Why Are Images So Important?

The first impression people have of a brand is determined by the visual impact for 55% (Source: US Chamber of Commerce). The images you use in your communication play a significant role in the impression the audience forms about you or your business. To avoid negatively impacting your company, it’s crucial, if not vital, to present yourself well.

A Warning About Resizing Photos While Maintaining Quality

Our goal is to resize images without losing quality. To do so, having the right tools isn’t enough: when working with photos (rather than vector images), we can only maintain quality if we start with a very large image that we want to shrink. If we try to enlarge a small photo, it will likely become blurry. We can make slight adjustments, but to maintain quality, we cannot enlarge it too much.

Only vector images (such as logos and illustrations) can be resized without limits.

How to Resize Photos with Photoshop

Do you have the Adobe package installed on your computer? Then you can’t go wrong: use Photoshop to resize your images. It’s the best tool at your disposal.

Here’s what you need to do:

1. Open the image you want to resize with Photoshop.

2. From the menu, click on “Image” and then “Image Size.”

3. Set the height, width, or resolution and choose the unit of measurement (pixels, centimeters, etc.). An important thing: to maintain aspect ratios, make sure the “Constrain Proportions” button is active.

4. Once you’ve set the parameters, click “OK” to apply the chosen dimensions and save the resized image.

Stop. You’re done. And for those who don’t have the Adobe package?

We’ve already talked about Adobe Express in our article on background removal in images. Well, this Adobe tool, 100% free, also allows you to adjust the dimensions of any photo in just a few seconds, making it smaller, vertical, horizontal, square, or tailored to your specific use—whether it’s for the web, a LinkedIn profile picture, a Twitter banner, or a YouTube thumbnail. Alternatively, you can set custom dimensions.

To resize or shrink a photo, follow these steps:

1. Upload the JPG or PNG file to the platform.

2. Choose your intended use or set custom dimensions.

3. Download the resized image or continue to edit it. At this point, if you haven’t already, you’ll be asked to register (registration is free).


BeFunky is also a very intuitive program that allows you to resize images online for free. The tool also offers photo editing, the ability to create graphic projects, or make photo collages (not all of these functions are available in the free plan).

Here’s how it works:

2. From the menu on the left, select “Resize.”

3. Set the desired dimensions, ensuring the “Lock Aspect Ratio” option is checked, so the image maintains the correct proportions.
