What is the right resolution for your images? - Concept C, Agence Web

What is the right resolution for your images?

An image makes text easier and more pleasant to read, it’s that simple! Why? Well, because a picture is worth a thousand words! We like to rest our eyes on something visual in a massive block of text.

It is also necessary that these images are readable and of good quality. No one likes to look at images that are too dark or poorly calibrated. This is true for all types of reading material, and websites are no exception. Read on to understand why Concept C uses high quality images and why you should too.

High quality images make any content more interesting, especially when trying to convey important information. Like proving the existence of UFOs for example.


Resolution and size

cercles_resolution_Plan de travail 1

A digital image is made up of a mass of small colored dots called pixels. Resolution is calculated based on the number of pixels (dots) that are in a square inch. The more dots, the higher the resolution.


Printed: DPI : Dots Per Inch

Web: PPI : Pixels Per Inch

** BUT: you will most often hear DPI for print AND web. We will only use DPI in this text to keep it simple.



The resolution and size of an image depend on the media (where your image will appear: web or print). Each media has its optimum resolution and minimum size. For example, web images should be as light as possible to not slow down the page.

Your graphic designer will ask you for a minimum of 300 DPI. This is a standard that can be easily declined. Whether for the web or in print, we can generally do anything with an image at 300 DPI.

You don’t need to understand quantum mathematics to assess whether an image is suitable. If you take your photos yourself with a real camera (not a Nokia 2004 phone please…) you should be okay.

JUST A TIP: If you’re opening a photo that looks crisp AND large, that’s already a good sign, but it’s always best to confirm with your graphic designer.

Put your cursor over the image file, and right-click on your mouse. Go to properties in the drop-down menu. You will then see the size, weight, resolution and aspect ratio of the image.

For print:

A minimum of 300 DPI at actual image size required. Example: A magazine with an 8 x 12 inch cover image. The image must therefore be 8 x 12 inches AND be at 300 DPI.

For the web:

Your screen is made up of pixels and the dimensions of the images are calculated in the same way. Resolution and dimension are determined by the total number of pixels that make up your image. Ex: 1200 pixels wide x 900 pixels high.


When you stretch an image to make it bigger, you cannot add pixels (dots). So when you enlarge the square inch, you also enlarge the individual points. They become much more noticeable and the image becomes pixelated (blurry).

The format :

The format is what will determine where and how it can be viewed or edited. These are the extensions at the end of your image name: example_image.jpg.

The types of extensions (formats) are:

Native: which originates from and interacts with a particular software. Ex: .AI, .PSD, etc.

Compressed: whose resolution has been flattened to reduce weight. Photos are generally in these lighter formats. Ex: .pdf, .jpg, .png, etc.



It is a UNIVERSAL format. This means that it can be opened on all devices. It offers good quality and is not too heavy. It can be printed as is.


Allows the background to be transparent. Great for logos, lightweight graphics, perfect for web or PPT presentation.


Most common, web format or print. It is highly COMPRESSED. It’s lightweight and that’s why it’s prioritized on the web. This is the format in which your images will be requested the most often.


The more you compress an image, the lower its quality. If you save a good quality .jpg in a Word document, and then save it as a .pdf, it counts as double compression. It’s kind of like putting a Neon engine in a Mustang and trying to make the car look like a real Mustang … Don’t do that.

Choose the right image

No matter what medium you use to promote your business or your services, it is essential that the image is of good quality. Then choose an image that speaks in the same direction as you. Choose images that represent the spirit of your business and don’t try to show it all. (If you sell kitchenware, we don’t need to see a kitchen overloaded with colanders of all colors.) What is important is to give the right feeling, to make the viewer feel the mood. Because a consumer doesn’t just buy a product, he buys an emotion, an impression.

In conclusion, before selecting an image, keep in mind: the format, the dimension and the resolution necessary to obtain the desired result. Still unsure? Consult your graphic designer, she will be able to guide you!
