Twitter Card Generator — Q&A

A single-file, Blogger-ready web tool that helps you create twitter:* meta tags, preview how a Twitter card will look, and export a ready-to-paste HTML snippet or downloadable demo page.

The tool supports summary, summary_large_image, player, and app card types, with the specific fields shown dynamically for each type.

For summary_large_image use 1200×628 px (recommended). For summary cards a small thumbnail is fine. Keep file size reasonable (≤ 5MB suggested) and use common formats (.jpg, .png, .webp).

Player cards require additional fields: twitter:player (embed page), twitter:player:width, and twitter:player:height. The tool shows a mock preview (no real playback) and validates required player fields.

Open Blogger → Theme → Edit HTML, then paste the generated <meta name="twitter:..."> tags inside the <head> section of your template. If your Blogger theme strips scripts, host the generated file externally and embed via an <iframe> in a post.

The tool validates the image URL extension and attempts to load it to read natural dimensions. If the image is blocked by CORS, invalid, or the URL is incorrect, a placeholder appears. Ensure the URL is accessible and ends with a supported extension.

Yes. Use the "Download .html" button — the tool creates a small demo page containing the generated head snippet so you can test how Twitter or other crawlers see the page.

This tool can be used without jQuery if required; otherwise ensure jQuery is loaded before the script or use jQuery.noConflict() and call the code with jQuery(function($){ ... }). A pure-JS build is provided in the tool's options.
