• Social Protocol Compliance: Output meta tags follow OpenGraph Protocol (ogp.me) and Twitter Developer Documentation for maximum fidelity across Facebook, LinkedIn, X, Slack, Discord, and Telegram.
• Image Dimensions: High-resolution banners should use 1200 × 630 pixels (1.91:1 ratio) to avoid automatic cropping on Retina screens.
• Multi-Platform Fallbacks: When specific Twitter tags are omitted, social crawlers seamlessly inherit primary OpenGraph values.
• 100% In-Browser Privacy: All meta tag assembly and live card simulations execute strictly in local browser memory.
Overview
What does OpenGraph Preview Generator do?
Open Graph tags control how your page appears when shared on social media — the title, description, and image in a link preview. This tool formats your title and description to the sizes those platforms display.
The title is capped at 60 characters and the description at 160 — the approximate lengths at which social platforms truncate preview text. The output shows both with their character counts, ready to paste into your Open Graph tags.
It is a sizing and formatting helper, not a full preview renderer: it gets your text to the right length and shape; the actual visual rendering happens on the platform when the link is shared.
Under the hood
How does it work?
The tool reads your input line by line: the first line becomes the Open Graph title, the second becomes the description, each truncated to the display length social platforms use.
The formatting is local string handling — no request is made to any server, and your input never leaves your device.
The output shows the formatted title and description with their character counts, ready to copy into your og:title and og:description tags.

Technical information
How the details work
Open Graph is a protocol that lets pages declare how they should appear when shared: og:title, og:description, og:image, and og:url are the core tags. When someone shares a link, the platform reads these tags and renders the preview from them.
Display limits matter because platforms truncate: a title longer than roughly 60 characters gets cut, and a description beyond roughly 160 characters is truncated with an ellipsis. Text within the limits displays in full.
The OG tags should match the page's actual content — the title and description you declare are what people see, so accurate, compelling text performs better than generic or mismatched copy. Testing tools from the platforms themselves show exactly how your tags render.

Frequently asked questions
Common questions about OpenGraph Preview Generator
What are Open Graph tags?
Open Graph tags are meta tags that tell social platforms how to render your page in a link preview — title, description, and image. They control what people see when they share your URL.
How long should an OG title be?
Around 60 characters or fewer. Longer titles are truncated in social previews, so keeping the important words early ensures they display.
Does this render the actual preview?
No. This tool sizes and formats your title and description text. The visual preview is rendered by the platform when the link is shared — use the platform's own testing tools to see it.
What about the OG image?
This tool handles title and description. The og:image tag is set separately in your page's head — most platforms recommend a 1200×630 image.
Is my input private?
Yes. Formatting happens locally in your browser and nothing you type is sent anywhere.
