Frequently asked questions
Is anything uploaded?
No. Every tag is generated in your browser from what you type, with nothing uploaded. It works offline once loaded.
What size should the social image be?
Use an absolute HTTPS image around 1200 by 630 pixels (a 1.91 to 1 ratio). That size looks right on Facebook, X, LinkedIn, Slack, Discord and most other platforms.
How long should the title and description be?
Aim for a title under about 60 characters and a meta description under about 155, so search engines do not truncate them. The counters turn red when you go over.
Do I need separate Twitter tags?
X and other platforms read Open Graph tags as a fallback, but adding twitter:card and the twitter tags gives you full control over how the card looks, so this tool includes both.
Where do I put the generated tags?
Paste them inside the head section of your page's HTML, ideally near the top, so crawlers find them in the initial response.
