The Share Preview Nobody Checks
Share a link on LinkedIn or Twitter right now. Paste one of your blog posts into the composer and look at the preview card.
If you see a gray box where the image should be, a title that got cut off, or your site description reading "just another WordPress site," you've got an OG image problem. I've checked hundreds of sites with the OG Image Generator and the majority have at least one issue.
OG images are one of the few things you can control about how your content looks everywhere else on the internet. A broken preview card kills click-through rates before anyone reads your headline.
The Most Common OG Image Problems
After scanning hundreds of URLs with the tool, these are the issues I see over and over:
- •No og:image tag at all. More common than you'd think. The result is a text-only preview card that gets scrolled past.
- •Image URL returns a 404. The tag exists but points to an image that's been moved, renamed, or deleted.
- •Wrong image dimensions. The recommended size is 1200x630 pixels (1.91:1 ratio). A 400x400 image gets awkwardly cropped.
- •Image is too large to load. Twitter's limit is about 5MB. High-res photos at 8MB won't render.
- •Missing og:title or og:description. Platforms fall back to your page's title tag, which might pull in something like "Page 1 | My Website."
- •HTTP vs HTTPS mismatch. Your site runs on HTTPS but the og:image URL still uses HTTP.
What the OG Image Tool Does
The tool has two modes: Preview and Generate.
Preview mode takes any URL, fetches its OG and Twitter Card meta tags, and shows you how your page looks when shared on Twitter, LinkedIn, Facebook, Slack, and iMessage. It also runs validation and flags issues: missing tags, wrong dimensions, broken URLs.
Generator mode lets you create new OG images from scratch. Pick from 13 templates (gradient, split, overlay, magazine, minimal, and more), customize colors and fonts, upload photos, and download a 1200x630 PNG.
Check how your pages look when shared on social, find what's broken, and generate polished OG images from 13 templates.

Running the preview check on your key pages tells you:
- •Which pages have no OG image. Fix these first. Text-only social cards get significantly lower engagement.
- •Which images are the wrong size. You want 1200x630. Anything else risks awkward cropping.
- •Whether your titles are getting truncated. OG titles should be under 60 characters.
- •If your descriptions are pulling correctly. Sometimes the og:description is missing and platforms fall back to a random paragraph.
- •How each platform renders your card. Twitter, LinkedIn, and Facebook all handle OG data slightly differently.
Tips for Better OG Images
A few quick wins that make a real difference:
- •Keep text on the image large and minimal. Readable in a thumbnail view. If you're squinting on your phone, it's too small.
- •Use high contrast. Dark text on dark backgrounds gets lost. Gold-on-dark or white-on-dark work well.
- •Don't rely on the image alone. The og:title and og:description text show below the image. Write them to drive clicks.
- •Test on multiple platforms. An image that looks great on Twitter might get cropped oddly on LinkedIn.
- •Use a consistent brand style. When all your OG images share the same colors and font, people start recognizing your content in their feed.
- •Update old posts. Popular content from years ago may have broken OG tags after theme updates and CMS migrations.
Frequently Asked Questions
1200x630 pixels at a 1.91:1 aspect ratio. This is the standard across Twitter/X, LinkedIn, Facebook, Slack, and iMessage. Some platforms will accept different sizes, but 1200x630 gives you the best results everywhere without awkward cropping. The OG Image Generator creates images at this exact size automatically.
You can set a separate twitter:image meta tag, but most people use the same image for both. The OG Image Generator creates images at the standard 1.91:1 ratio that works across all platforms. Where it really matters is the og:title and og:description text, which shows up differently on each platform. The tool previews how your card looks on Twitter, LinkedIn, Facebook, Slack, and iMessage side by side.
No. URLs you enter and images you create are processed in the session only. Nothing is saved to any server. Close the tab and everything is gone. Same privacy-first approach across all tools in the free suite.
Platforms cache OG data aggressively, sometimes for days. After updating your tags, you need to manually clear each platform's cache. Use the Twitter Card Validator, LinkedIn Post Inspector, and Facebook Sharing Debugger to force a refresh. Once the cache clears, your updated image and metadata will show up on new shares.
