A slide is designed to be seen while someone speaks. A blog graphic has to explain itself beside written text, often on a phone. That difference is why small labels, presenter shorthand, and crowded diagrams fail when a slide becomes a static article image.
Find the graphic’s one job
Open the source slide and its notes. Write a sentence naming what the reader should learn from the visual. If the slide contains several claims, split them: one may belong in a paragraph, another in a table, and only the spatial relationship may need a graphic. A blog image should not carry a paragraph of tiny text simply because it fit on a large presentation screen.
For an illustrative example, imagine a slide titled “Three parts of a usable page header” with separate bullets about logo, navigation, and a primary action. In a blog tutorial, the bullets can become page text. The graphic can show the placement and hierarchy of those three elements on a desktop and narrow layout. This is a proposed teaching example, not a reported redesign.
Translate slide elements into article elements
| On the slide | In the blog post | Check |
|---|---|---|
| Title and several bullets | Use a heading and short paragraphs or list in HTML. | Can the image still make sense without repeating all the prose? |
| Diagram with labels | Redraw the relationship with fewer, larger labels. | Are arrows, order, and labels correct at mobile size? |
| Chart | Recreate it from the original data and explain the takeaway in text. | Are values, units, source, and scale preserved? |
| Decorative photo | Use it only if it supports the article’s point and rights permit reuse. | Will the crop still work in the post layout? |
If you no longer have the chart’s source data, do not ask AI to rebuild its values from a screenshot. Find the data or remove the quantitative claim. An attractive redraw with guessed numbers is worse than no chart.
Give AI a bounded conversion task
Paste only the slide text and the presenter’s explanation you are entitled to use. Ask for a content plan, not a fabricated finished figure:
Turn this presentation slide and speaker note into a blog-graphic brief. State the single point the graphic needs to show. Separate text that belongs in HTML from labels that must remain in the image. Suggest a layout that will be legible at a narrow width. Preserve all names, numbers, units, and relationships exactly. Flag anything that cannot be determined from the source; do not fill gaps.
Check the proposed brief against the slide before you design. A model may simplify a diagram by dropping a necessary condition, or turn a cautious claim into a definite one. Keep the original source available during the rebuild.
Rebuild and preview at the final size
Set the canvas to the width and aspect ratio used by the article, not the slide deck. Make labels large enough for the rendered post. Leave breathing room around the important element so a responsive crop does not cut it away. Export the graphic and inspect it in the page preview rather than judging the editor canvas.
If the graphic conveys information, give it a text alternative that states its essential point. If a complex chart needs more explanation, provide that in the surrounding article. The W3C images tutorial explains how alternatives depend on an image’s purpose. A purely decorative image can be marked accordingly.
Keep the source trail
Save the original slide, the rewritten brief, and the final graphic. If the source is someone else’s presentation, check permission and attribute it as required. If the image changes a chart or quote, document the change in the article. The useful result is a graphic that supports the tutorial on its own terms, with no invented evidence hidden in a polished export.
