An AI-generated cover can look excellent inside a tool and arrive on the website far too heavy. It can also lose its subject in a mobile crop or contain strange details that only appear when enlarged. Publishing requires preparation beyond generation.
Choosing between WebP, AVIF and other formats belongs to that process, but the decision should not depend on the file extension alone. The goal is to preserve the necessary visual information in a file appropriate to its placement. Start with the image’s role in the content.
Separate the master from the published version
Keep the original file in an identified production folder. The version delivered to the browser may be smaller, cropped and compressed for its purpose. This separation lets you repeat an export without needing to generate a similar illustration again. Record the article or section it belongs to.
For an abstract cover, preserve the relationship between elements that expresses its topic. For an image of a product or environment, check whether editing preserves an appropriate representation. A photograph of real work and a conceptual illustration serve different purposes; provide the corresponding context.
Compare formats using the same image and dimensions
The web.dev guide includes WebP and AVIF among modern image formats used on the web. They offer compression alternatives without making either one mandatory for every file. Visual content and export settings influence the result.
Export candidates at matching dimensions and compare the files in their actual presentation. Look for bands in gradients, broken edges, blurred textures and unexpected transparency. A cover with smooth surfaces may require a different choice from an interface screenshot full of detail. Do not promise a fixed reduction without measuring that particular file.
Choose the framing before compression
A large empty area can be useful behind an overlaid heading but look accidental when the image stands alone. Check its final use before exporting. In an article listing, the subject should remain recognisable at a small size. The article opening may allow more room to examine details.
Crop with important areas in mind, rather than only the frame ratio. If the subject disappears in a thumbnail, adjusting composition may work better than increasing sharpness. For AI-generated covers, a clear initial description often helps more than trying to rescue a confused concept with filters.
Review what the AI drew before optimising
Look at the image as part of a company publication. Check malformed objects, meaningless lettering, unwanted brands and potentially misleading interpretations. A visually appealing scene can communicate something different from the article. Approval should consider the topic, rather than appearance alone.
Use illustration to support an idea and avoid presenting it as documentation of a project that never happened. For an article about a process, a visual metaphor may work better than an invented interface. Covers feel more coherent when they share direction without repeating exactly the same scene.
- Check the subject at card size and article-opening size.
- Remove rejected versions from the publishing package.
- Use clear filenames related to the content.
Include the image in the publishing review
Open the page with its final image, rather than only viewing the exported file in a folder. Review occupied space, cropping and behaviour while content appears. Check the sharing card too: a cover that works in the article may need another composition for a social preview.
Alternative text should follow the image’s editorial purpose. Describe what it adds when needed, without stacking keywords. If an image simply repeats a card link visually, implementation can avoid redundant reading. Make that decision for the complete component.
Make visual quality support the presentation
A coherent cover collection unifies the blog and helps identify its publisher. Materials, lighting, colours and framing can create that unity without forcing every topic into the same drawing. Editorial work still means choosing a relevant image.
In MissaciWeb projects, content presentation should connect to identity and navigation. When planning a blog linked to a business website or store, organise image production and updates too. That makes it easier to maintain visual care after the initial publication.
For a concrete example of images working with a brand, explore the Gráfica Jobi website case. If you are planning a company presentation, compare the content and image requirements in the business website plan.
A checklist to take away
- Keep a master and export versions for each purpose.
- Compare formats at matching dimensions in their real context.
- Review artefacts and interpretations in AI-generated images.
- Check cropping, cards and sharing previews.
- Match filenames and alternative text to editorial purpose.
