Generate SEO, Open Graph and Twitter card meta tags. Free, runs entirely in your browser — no signup, and nothing you paste in is uploaded.

The title and description are the two that do real work, and both are budgeted in pixels rather than characters — roughly 60 characters of title and 155 of description before truncation, less if your text is full of wide letters. The description is not a ranking factor, but it is the sales copy under the link, and a good one changes whether the click happens.

Open Graph and Twitter tags exist because social platforms do not read the standard ones. Their crawlers also do not run JavaScript, which is the detail that catches single-page apps: tags injected at runtime are invisible to them, so the preview falls back to whatever is in the served HTML.
