Fetching your page and its share tags…

The first impression of every link you share

When you (or a customer) drop your link into a Facebook post, a text message, or a LinkedIn update, the title, blurb, and image that pop up are pulled from invisible meta tags in your page. Get them wrong and the preview is blank, cropped, or shows the wrong page. This tool reads the tags your site actually serves and shows you all three previews side by side, then hands you the corrected tags.

How it works

Enter a URL and we fetch the live page with a normal browser User-Agent, then parse the real <title>, meta description, every og:* and twitter:* tag, and the favicon. We render how the link looks on Facebook, in iMessage and on X (the Twitter card), and on LinkedIn, using only the values we found. Nothing is invented. If a tag is missing, we say so.

The corrected meta generator

Below the previews we build a copy-paste block of recommended og:title, og:description, og:image, og:url, twitter:card and friends. It reuses the good values we found and flags the ones you are missing, so you (or your developer) can paste a complete, correct set into your page head. We never make up a title, description, or image, the generator is grounded only in the tags that were actually fetched.

How we compare

Paid checkers like OpenGraph.io cap you at around 100 free requests a month before charging, and OpenGraph.xyz pushes a premium tier for more than the basics. Ours is unmetered, shows multi-platform previews on one screen, and adds a corrected-meta generator that is grounded only in your real tags. No account, no request quota, no upsell to see your own previews.

Pro tips

Use an absolute og:image URL (https://yourdomain.com/share.jpg), not a relative path, or some platforms show nothing.
Size your share image at 1200 by 630 pixels and keep text away from the edges so it is not cropped.
After changing tags, re-scrape your link in the Facebook Sharing Debugger and LinkedIn Post Inspector to clear the old cache.
Set twitter:card to summary_large_image if you want the big image on X and iMessage instead of a tiny thumbnail.
Keep og:title under ~60 characters and og:description under ~110 so nothing gets truncated.

Frequently asked questions

What are Open Graph (og:) tags?

Open Graph tags are meta tags in your page head (og:title, og:description, og:image, og:url) that tell Facebook, LinkedIn, iMessage, and most chat apps what title, summary, and image to show when someone shares your link. Without them, those apps guess, and the preview often looks broken.

Why does my link show no image when I share it?

Usually because there is no og:image tag, the image URL is relative or broken, or the image is too small. Add an absolute og:image URL that points to a 1200 by 630 pixel image, then re-scrape the link in the platform debugger.

What size should my share image be?

1200 by 630 pixels (a 1.91 to 1 ratio) is the safe standard for Facebook, LinkedIn, and X large cards. Keep important text away from the edges, and host the image over https so it loads everywhere.

Does this tool change my website?

No. It only reads the tags your page already serves and shows you how the preview looks. It never invents tags. The corrected meta block it generates is copy-paste HTML that you (or your developer) add to your page head yourself.
