Frequently Asked Questions

A good all-around size is 1200 by 628 pixels. It usually fits most blog themes and also looks right when people share your post. Keep the main subject and any text near the center so it still looks fine if your theme crops the edges. If your theme recommends a different size, follow that and stay consistent with your featured image creator images.
If you want one ratio that works in most places, go with 16 by 9. It suits blog headers and social previews, and it is easy to reuse across posts. Try to export at least 1200 pixels wide so it stays sharp. Center the focus so your AI-featured image generator visuals do not lose the important part after cropping.
1200 by 630 is the size people use most often for share previews. It generally shows up well on platforms that use Open Graph-style cards. Leave a little breathing space around logos and text because previews can crop. Saving a simple template in your blog banner generator makes sharing smoother.
The easiest fix is to design with a safe center area. Put the main subject and the key words in the middle and leave extra padding on all sides. Different apps crop in different ways, so edge text is always risky. Once you have a layout that works, reuse it in your blog header image generator.
Most of the time it is not the image, it is how the site is displaying it. Your theme may be pulling a small thumbnail-sized image or stretching a smaller file to fit a larger box. Check your media settings, regenerate thumbnails if needed, and upload a higher resolution file. In Serplux, export bigger and let the featured image creator output scale down, not up.
Text can help, but only when it is truly needed. If you add it, keep it short, make it readable on mobile, and avoid placing it near the edges. If the headline already explains the post, a clean image often looks better. Many Serplux users keep it simple and rely on the blog banner maker mainly for layout and branding.
WebP is a practical choice because it loads faster while still looking good. If your site supports AVIF, that can be even lighter, but WebP is usually the easiest option. Export close to the final display size so your site does not have to resize too much. With Serplux, WebP from the blog post image generator is a solid default for speed.
Yes, especially the first big image people see. If that file is heavy, the page can feel slow even if the text loads quickly. Resize images to what you actually need, compress them, and use modern formats. A good blog image creator process also means lazy loading images that sit further down the page.
Write it like you are explaining the image to someone who cannot see it. Keep it clear, specific, and tied to the post topic. Do not force keywords into it. If the image is just decorative, you can keep alt text empty instead of writing something useless for your blog header image creator graphic.
Yes, if it is truly decorative and not adding information. Empty alt text helps screen readers skip it and focus on content that matters. Just be honest with the decision, because if the image contains meaning, it should have alt text. This applies even if you made it with a blog banner generator.
It is not a great habit. Repeating alt text does not help accessibility, and it also makes your content feel copy-pasted. Give each image a short description that matches what it shows and what the post is about. Serplux makes it easy to produce variations, so each featured image creator image can have better, more accurate alt text.
In many cases, yes, but you should still check the tool terms and be careful with what you generate. Avoid logos, brand characters, and real people unless you have rights. If you are using Serplux, keep your prompts and edits saved so you have a clear record of how the AI-featured image generator visual was created.
