What Does Resizing an Image Really Mean
The dimensions (height and width) of an image are measured in pixels: a pixel is the unit measure to identify the space an image takes up on the screen.
File size, on the other hand, is the amount of storage space your image will occupy: it’s measured in kilobytes (KB) and megabytes (MB), where 1MB = 1000KB.
Dimensions and file size are strictly related: the larger the dimensions of an image, the larger its file size will be.
Images for the web can also be defined by their pixel resolution, which is usually adopted to indicate the quality of an image. This measure is expressed by two numbers, for example, 1024 × 768 (where the first is the number of pixel columns, and the second is the number of pixel rows).
Resizing an image for the web means reducing its width and height, which will also end up reducing its file size.
When the size of an image is reduced, the photo editor of your choice will automatically remove the unnecessary pixel information and change the dimension of the file.
So we can define resizing as dealing with the physical dimensions of an image.
How to Determine the Right Size for an Image?
To get your images ready to be uploaded on the web, you should make sure they have the right height and width for the content area of the page where you’ll place them.
It’s very important to figure out in advance how wide the content area of your web page is: to save resources and page load time, always avoid uploading images wider than that portion of the page.
There are several tools that allow you to assess the right width of your content area. The quickest ones are the following:
- From the browser (be it Chrome, Firefox or Safari), you can right-click on any page element and choose Inspect Element to open Developers Tools. It will instantaneously indicate the dimensions of the content area of your interest:
- For Apple users, you can profit from Mac’s built-in capture tool, Grab: you can activate it with Command+Shift+4. When you draft an area on the screen, you will see the pixels of that area.
How to Resize an Image on a Windows PC
Probably one of the most versatile tools for image editing, a PC will usually come with programs that allow you to edit images. In addition, some of the best photo editing tools are available for PC. We’ll list a few programs along with some tips on how to reduce images:
All Windows versions below Windows 10 will come with MS Paint by default. Although quite basic as photo editing tools go, it can still resize pictures rather easily. To do so, follow these steps:
- Open the image by either right-clicking on it and selecting Open With, or clicking File, then Open on the Paint top menu.
- On the Home tab, under Image, click on Resize.
- Adjust the image size either by percentage or pixels as you see fit. Click on Maintain Aspect ratio to keep the image size constant when adjusting by percentage.
- Click on OK.
2. Paint 3D
Windows 10 comes with an updated version of the Paint app which has a lot more options than the original. The interface has been changed quite a bit though, so those familiar with the previous program may find themselves lost when trying to navigate the menus. To resize an image in Paint 3D, do the following:
- Open the image in Paint 3D.
- Click on the Canvas tool at the top menu.
3. Adobe Photoshop
Considered one of the best image tools around, you can not really think of photo-editing without mentioning Adobe Photoshop. Although not free as the others mentioned, this program’s versatility is well worth the price. To resize an image in Photoshop, follow these steps:
- Click on ‘Image’ in the top menu.
- Choose Image Size.
- Adjust the dimensions as you see fit the click on OK.
Batch resizing can also be done, though it will require recording Actions, then proceeding to choose File, Automate, then Batch.
A free and very popular image viewer, Irfanview also has the ability to resize images, both individually, and by batches without having to record program actions first. It is a very handy tool to have, and as it costs nothing to install, there really is not a reason not to give this program a try. You can resize images in Irfanview like so:
- Open the image by right-clicking and choosing Open With, or finding it through the Irfanview menu by clicking File, then Open.
- Click on Image on the top menu then click on Resize/Resample.
- Adjust the image values as you see fit, then click on OK.
Batch conversion of images located in one folder can be done by opening Irfanview, clicking on File, then choosing Batch Conversion/Rename. All images located in the folder will then be resized automatically.
Step 3 Class Skeleton
It’s Object-Oriented Programming (OOP) that makes this sense of ease possible. Think of a class like a pattern; you can encapsulate the data — another jargon term that really just means hiding the data. We can then reuse this class over and over without the need to rewrite any of the resizing code — you only need to call the appropriate methods just as we did in step two. Once our pattern has been created, we create instances of this pattern, called objects.
«The construct function, known as a constructor, is a special class method that gets called by the class when you create a new object.»
Let’s begin creating our resize class. Open your resize-class.php file. Below is a really basic class skeleton structure which I’ve named ‘resize’. Note the class variable comment line; this is were we’ll start adding our important class variables later.
The construct function, known as a constructor, is a special class method (the term «method» is the same as function, however, when talking about classes and objects the term method is often used) that gets called by the class when you create a new object. This makes it suitable for us to do some initializing — which we’ll do in the next step.
Note that’s a double underscore for the construct method.

Get to know social media sizes so your posts look their best wherever they are displayed. To make sure your photos look drop-dead gorgeous on all of your social media channels while avoiding the dreaded “file too small” or “file too large” messages, visit our chart of common social media image sizes, then crop and resize away.
Don’t feel like thinking about it? Use the Crop tool to quickly find the correct aspect ratio for your desired social channel. You can also start with a pre-sized social media template or blank canvas so that you never have to worry about sizing-gone-wrong. If you’re on PicMonkey mobile, scroll through the carousel under Start a new design to select the correct social size.
Of course, if you need to size an image for multiple channels, then meet.

At the bottom of the menu, click Resize to simply alter the current image to the new size, or Copy & resize if you want to keep the original as is while creating a resized version as well.
It’s done! Check Hub to see all your new sizes.
Did We Miss Any Tools?
Even though image size and quality are important for websites and blogs, remember that image SEO is just as important for maximizing the amount of search engine traffic you capture. Don’t neglect that aspect.
Note that if you’re using one of these tools as a photographer and you have aspirations to be professional or semi-professional, we recommend learning to use something like Photoshop or Lightroom instead.
If we missed any other batch resizers, optimizers, or converters, please let us know in the comments below! Otherwise, tell us which ones are your favorite and what you used these tools for. We’d love to hear from you!
