Prefer Large Image Cards
Use summary_large_image with a clean 2:1 crop when the image is important to the click and brand presentation.
Generate Twitter Card tags with a live X/Twitter-style preview for both small summary and large image cards.
Check out this page preview before you publish it.
<!-- Twitter Card --> <meta name="twitter:card" content="summary" /> <meta name="twitter:site" content="@gap3studio" /> <meta name="twitter:title" content="GAP3 Tools | Free Online Utilities for Developers" /> <meta name="twitter:description" content="Powerful free tools for developers: JSON formatter, UUID generator, color converter, and more.

Use summary_large_image with a clean 2:1 crop when the image is important to the click and brand presentation.
Twitter can fall back to Open Graph tags, but dedicated twitter:* tags give you more predictable previews.
Validate or rescrape card output after deployment so cached previews update with your newest title, text, and image.
