How to choose the right images for your website
The right images explain your offer faster, support trust and help the website stay fast on mobile.
Images on a website are not only decorative. They can explain a service, show the result of a project and help visitors understand what you offer more quickly.
A good image should match the message, audience and place where it is used. A beautiful image that is too heavy or unrelated to the page can slow the site down and create confusion.
Choose images based on the page goal
Before looking for a photo, decide what visitors need to understand. A hero image can introduce the service, project images can show the result and an explanatory graphic can simplify a process.
- present the service
- show a concrete result
- explain a process step
- support proof or an example
- create the right atmosphere
Use images that relate to the business
Generic images can look polished but do not always say anything about how you work. Choose real projects, process details or scenes that reflect your audience and service.
If you use generated or library images, check that they do not contain elements that contradict your offer or brand style.
Design the composition for every device
An image that works on a monitor may be cropped on a phone. Keep the important subject in a visible area and check the image in portrait, square and landscape formats.
On responsive pages, the image should remain clear without pushing important content too far down. The right composition supports both design and the mobile experience.
Optimize files before publishing
File size and format directly affect speed. Use WebP or AVIF when appropriate, export the image at its real display size and avoid uploading a file much larger than the area where it will appear.
- resize images before uploading
- choose WebP or AVIF for photographs
- keep JPG when it is sufficient
- lazy-load images below the first screen
- check the result on a mobile connection
Do not forget alt text
Alternative text describes an image for people using assistive technology and for situations where the image cannot load. Describe what matters for the page, not a list of keywords.
Decorative images can use empty alt text so screen readers do not announce unnecessary information.
Connect images to content and SEO
The file name, alt text, page title and surrounding copy should support the same subject. A project image can link to that project, while an article image can lead to the service it explains.
Internal links between articles and services help visitors continue and give search engines clearer context.
Check everything before publishing
Review the page on desktop, phone and tablet. Check that the image loads quickly, the subject remains visible and the alt text describes its role correctly.
A coherent, optimized and relevant image library makes a website clearer without harming performance.
