Open Graph Generator

Generate the four required Open Graph properties plus validated optional description, site name and locale with exact HTML escaping and no platform-specific guesswork.

Privacy: your files never leave your device. All processing happens locally in your browser.

How to use

  1. 1.Enter accurate object text, choose website or article, and provide public fragment-free page and image URLs.
  2. 2.Generate the required and optional Open Graph properties, then copy the protocol-only block into the canonical page head.
  3. 3.Inspect delivered source and use each target platform's current preview debugger to check crawl access, image handling and cache refresh.

About Open Graph Generator

Open Graph Generator creates protocol metadata that describes a web page as a shareable graph object. Enter a title, object type, canonical object URL and image URL, then optionally add a description, site name and locale. The tool returns property-based meta elements in stable order and performs all work in the browser.

The Open Graph Protocol defines four basic required properties: og:title, og:type, og:image and og:url. The generator always emits those first. Title names the object, type classifies it, image supplies a representative visual and URL identifies the permanent object. Missing any required value blocks output rather than creating an incomplete preview block.

The available object types are deliberately limited to website and article. The broader protocol ecosystem includes music, video, profile and other structured types with required or optional properties of their own. Exposing a generic free-text type would let the form produce unsupported combinations without the corresponding structured fields. Use a specialized implementation when the object needs a richer type.

Page and image values must be absolute HTTP or HTTPS URLs without embedded credentials or fragments. The browser URL parser normalizes them. A fragment-free object URL keeps shares of the same resource from splitting across client-side anchors, while credential rejection avoids copying user information into public metadata. The tool does not fetch either URL.

The image URL should point to a publicly reachable image that the target sharing service can crawl. This generator cannot verify HTTP status, MIME type, dimensions, byte size, aspect ratio, redirects, robots controls, authentication or platform cache state. Each social service applies its own image requirements and may continue showing an older cached preview after metadata changes.

Optional og:description summarizes the object, og:site_name names the larger site and og:locale uses language_TERRITORY form such as en_US. The locale validator intentionally accepts one conservative two-letter language and two-letter territory shape. Alternate locales and script subtags need additional protocol properties and editorial decisions outside this focused form.

Text is trimmed, length bounded, rejected when it contains control characters and escaped for an HTML attribute. Ampersands, quotes and angle brackets cannot break the generated meta element. The object type is checked again at runtime even though the interface uses a select control, protecting the pure logic entry from altered or programmatic input.

The output follows Open Graph property syntax, not name syntax. Put the meta elements in the HTML head of the canonical page. Do not place them as visible text, encode the whole block again or duplicate them through both a framework and plugin. Inspect delivered source because build tools can reorder, overwrite or add conflicting properties.

This tool does not generate Twitter Card metadata. Platforms can consume some Open Graph properties as fallbacks, but Twitter or other service-specific tags and validation rules remain separate concerns. Keeping the protocols separate makes the copied result auditable and prevents an assumed cross-platform field from masquerading as a standard requirement.

Eight protocol fixtures cover all four required properties, the three optional properties and the article type. Additional tests assert exact HTML escaping and stable property count, then reject credential-bearing URLs, non-web image schemes, malformed locale, altered object type and control characters. Browser verification fills the actual form and proves clipboard output.

A valid Open Graph block does not guarantee how a post appears. Sharing systems can crop images, truncate text, ignore fields, choose cached data or apply account-level policies. Use each platform's current debugger or share inspector after deployment and allow for cache refresh behavior. The public page must remain accessible to its crawler.

Write metadata that matches visible content. A misleading title, description or image can disappoint visitors and undermine trust even if it earns a click. After publishing, compare raw source, the fetched image response and live platform previews, and update all representations together when the page moves or changes identity.

Methodology & sources

Required Open Graph fields are runtime validated, page and image addresses are normalized as fragment-free credential-free HTTP(S), optional text and conservative locale are bounded, all attribute values are escaped, and properties are serialized in required-first stable order.
