OGImage

Complete Open Graph Toolkit for Social Previews

OGImageSize is a comprehensive web application that helps developers, marketers, and SEO professionals create, validate, and optimize Open Graph images and meta tags for social media sharing. The platform ensures your shared links display correctly across Facebook, Twitter/X, LinkedIn, Slack, Discord, and other social platforms.

What It Solves

When you share a URL on social media, platforms crawl your page for Open Graph metadata to generate a preview card. Missing tags, wrong image dimensions, HTTPS issues, or stale platform caches can result in broken or unprofessional-looking previews. OGImageSize consolidates the entire social preview workflow—from image sizing to final validation—into one accessible toolkit.

Core Features & Tools

• OG Image Size Guide: Reference the recommended 1200×630px baseline, platform-specific dimensions, safe zones, and common cropping mistakes
• OG Image Generator: Create production-ready 1200×630px PNG images from fixed templates with proper aspect ratios for social cards
• Open Graph Preview: Test how your URL will appear when shared, with live checks for Open Graph tags, Twitter Cards, HTTPS compliance, and image availability
• OG Image Tester: Run diagnostic passes for og:image tags, dimensions, HTTPS enforcement, image response codes, and common preview blockers
• Meta Tags Generator: Generate copy-ready HTML meta tags, Twitter Card markup, and Next.js metadata configurations from a single form

Integrated Workflow

The platform follows a sequential validation chain: check size → generate image → copy tags → preview URL → fix issues. Each tool entry point connects to the next step, so a size lookup naturally progresses to image generation, valid markup, and final URL validation before publishing.

Platform Compatibility

OGImageSize validates against the specific requirements of Facebook shared link cards, X/Twitter large summary cards, LinkedIn article previews, Slack workspace unfurls, Discord link embeds, and generic Open Graph crawlers. The toolkit surfaces platform-specific cropping rules, absolute URL requirements, and cache refresh needs.

Who It's For

Built for developers implementing social sharing, SEO teams optimizing link previews, marketers preparing campaigns, and content creators who need professional social cards without design tools or logins. The first version is entirely free, indexable, and requires no account creation.
