Privacy-First Online Tools — ToolJutsu

A fast, free collection of developer and SEO tools that run entirely in your browser. Nothing you enter is ever uploaded.

Modern X also reads standard Open Graph tags (og:title, og:image and so on) as a fallback. Keeping both sets in your <head> gives the most reliable result across every platform.

How to use Twitter Card Generator

What this tool does

The Twitter Card Generator builds the <meta name="twitter:..." /> tags that control how your page looks when its link is shared on X (formerly Twitter). Choose a card type, fill in a title, description, image URL and the relevant @handles, and the tool assembles valid, copy-ready markup. A live preview updates as you type — showing the large-image layout or the compact summary layout depending on the card type you pick — so you can judge the result before the tags go anywhere near your site. One click copies the code into your page’s <head>.

X supports four card types. summary_large_image (the default) leads with a wide image and is best for articles, products and landing pages. summary shows a small square thumbnail for lighter links. app and player are specialised cards for mobile apps and embedded media.

Why it matters for SEO

Twitter Cards do not feed directly into Google’s ranking algorithm, but they shape the engagement that SEO ultimately depends on. A link that unfurls into a bold image with a clear headline stops the scroll; a bare URL does not. More clicks from X mean more sessions, more dwell time and more chances for someone to link to or re-share your page — the kinds of secondary signals that do influence organic visibility over time.

Cards also protect your brand. Left to guess, X will scrape whatever image and text it can find, which is often the wrong crop or a stray logo. Explicit twitter:* tags make every share look intentional and consistent, which matters when a single post can reach a large audience in minutes.

How to use it

  1. Pick a twitter:card type. Use Large image for most content; Summary for compact links.
  2. Enter a twitter:title of around 70 characters and a twitter:description of up to roughly 200 characters.
  3. Paste a twitter:image URL. Use a wide ~1200×628 image for large cards or a square image for summary cards, hosted on a public URL.
  4. Add twitter:site (the brand’s @handle) and twitter:creator (the author’s @handle). The tool adds the leading @ automatically.
  5. Review the live card preview, then copy the generated code into your <head>.

SEO best practices

Always use an absolute, publicly reachable image URL — X’s crawler must be able to fetch it from outside your domain. Match the image aspect ratio to the card type so nothing is cropped awkwardly. Front-load the title with the key idea, because long titles are truncated. Because modern X reads Open Graph tags as a fallback, keep both your og:* and twitter:* tags in place: that combination gives the most reliable preview across X, Facebook, LinkedIn and Slack alike. Validate important pages with X’s Card Validator (or simply paste the URL into a draft post) before you promote them.

Common mistakes to avoid

The biggest mistake is a missing or mis-sized image: no twitter:image yields a flat, text-only card, and a wrong aspect ratio gets cropped badly. Using a relative image path is another silent failure, since external crawlers cannot resolve it. Forgetting the @ on handles, or pasting a full profile URL instead of the handle, breaks attribution — paste just the handle and let the tool format it. Do not assume an updated tag is live immediately; X caches cards, so re-validate after changes. And avoid keyword-stuffing the title or description, which makes the card read as spam rather than a useful link.

Privacy & your data

This tool runs completely in your browser. It is plain JavaScript with no server component: the titles, descriptions, handles and image URLs you enter are processed on your own device and are never uploaded, logged or stored. The live preview loads your image URL straight from its host into your browser, just as any normal page would. There is no account, no tracking and no upload — once you close the tab, nothing you typed is kept anywhere.

Frequently asked questions

What is the difference between summary and summary_large_image?
A summary card shows a small square thumbnail beside the title and description — useful for quick links where the image is secondary. A summary_large_image card shows a wide, prominent image above the text, which earns far more attention in a busy timeline. For articles, products and landing pages, summary_large_image is almost always the better choice and is the default here.
What image size should a Twitter card use?
For summary_large_image, use roughly 1200×628 pixels (about a 2:1 ratio); X crops anything far from that shape. For a summary card, use a square image at least 144×144 pixels. Keep files under 5 MB and in JPG, PNG, WEBP or GIF format, and avoid placing essential text near the edges where cropping can clip it.
Do I need both twitter:site and twitter:creator?
Neither is required for the card to render, but both add useful attribution. twitter:site is the @handle of the website or brand publishing the page, and twitter:creator is the @handle of the individual author. Setting them lets X credit the right accounts and can surface an extra attribution line on the card.
Will my page still get a card if I only have Open Graph tags?
Usually yes. Modern X falls back to Open Graph tags, so a page with og:title, og:description and og:image will normally render a card even without twitter:* tags. Adding dedicated twitter:* tags still helps: it lets you set a card type explicitly and tailor the title, description or image specifically for X.
Is the information I enter kept private?
Yes. This generator runs entirely in your browser with JavaScript. The titles, descriptions, handles and image URLs you type are never uploaded, logged or saved on any server, and the preview loads your image URL directly from its host to your browser. Close the tab and nothing you entered is retained.
