SharePeak — Social Share Preview & Open Graph Checker

See how your link looks on X, Facebook, LinkedIn & 7 more before you post — and catch JS-injected tags that crawlers miss.

Ever shared a link and it showed up as an ugly blank box with no image or title? SharePeak shows you exactly how your page's link preview will look across every major social network and messaging app BEFORE you post it — and tells you exactly how to fix it when something's wrong. Click the icon on any page and instantly see: • PLAIN ENGLISH FOR NON-CODERS (Simple mode) — every problem is explained in plain words: what's wrong, why it matters, and exactly WHERE to fix it — with step-by-step guides for WordPress, Shopify, Wix, Squarespace, or raw HTML. Don't write code? You don't need to. One click flips to Developer mode for the raw tags and copy-paste fix. • ACCURATE PREVIEWS, PLATFORM BY PLATFORM — every major social network and messaging app crops images and truncates titles differently. SharePeak renders each preview the way that platform actually shows it, with a Desktop/Mobile toggle so you see both. • CRAWLER'S-EYE VIEW — SharePeak fetches your page the way social-media bots do (no JavaScript) and compares it to what's actually on the page. If your Open Graph tags are injected by JavaScript — the #1 reason previews show up blank on React, Next, Vue and other SPA sites — it flags them. Only a browser extension can see both versions at once. • REAL IMAGE VALIDATION — it actually fetches your preview image and checks the true dimensions, aspect ratio, file size and format against each platform's rules, then warns you when an image is too big, too small, or in an unsupported format. • A GRADE + A COPY-PASTE FIX — every page gets an A–D score, a clear list of issues (errors and warnings) separated from optional suggestions, and a ready-to-paste block of corrected meta tags. • WORKS WHERE OTHER TOOLS CAN'T — because it reads the page in your browser, it works on localhost, staging, and pages behind a login that public web-based debuggers can't reach. • ONE-CLICK DEBUG LINKS — jump straight to the official sharing debuggers and inspectors so you can re-scrape cached previews after a fix. PRIVACY: Everything runs locally in your browser. SharePeak reads the page you're on only when you click it (activeTab). It does not collect, store, or transmit any of your data, and it has no account, no tracking, and no analytics. Made for everyone who shares links — marketers, founders, and content creators who don't code (Simple mode explains everything), plus web developers and SEO pros who want the technical detail (Developer mode).
