FAQPage Schema

How do I regenerate banner PNGs from HTML after updating my site design?▼

Regenerate banner PNGs from HTML by re-rendering the updated source files using Chrome DevTools MCP. This captures the new design from your site HTML files and outputs fresh PNG assets.

Can I generate OpenGraph images at 1200x630 from HTML sources?▼

Yes, you can generate OpenGraph images by capturing HTML sources at a 1200x630 viewport setting. Chrome DevTools MCP renders the HTML and exports the result as an OG PNG asset.

How do I keep OpenGraph images in sync with light and dark mode HTML changes?▼

Keep OpenGraph images in sync by re-rendering both light and dark banner variants after editing the corresponding HTML files. The capture process updates all four PNG assets to match the latest HTML design.

What do I need to capture OG images from HTML using Chrome DevTools MCP?▼

You need control of your site HTML files in the site directory, the Chrome DevTools MCP workflow configured, and correct viewport settings set to 1200x630 to capture OG images from HTML.

Why are my regenerated banner PNGs not reflecting HTML updates?▼

Banner PNGs may not reflect HTML updates if the viewport settings are incorrect or the HTML files in the site directory were not saved before running the Chrome DevTools MCP capture process.

When do I need to re-render banner and OG image PNGs?▼

Re-render banner and OG image PNGs whenever you change site HTML files like site/readme-banner-dark.html. This ensures consistent previews and branding across the site after design updates.
