How to Use OG Image & Tag Preview Online Free
Using the simulator is incredibly easy, and honestly, a lot of fun. You get to play graphic designer and copywriter at the same time. Here is the step-by-step process:
- Draft Your Content: In the input panel, type out the title and description you want people to see when they encounter your link on social media.
- Add Your Image URL: This is the most crucial step. You need to upload your thumbnail image to your website or an image host, and then paste the direct URL to that image (e.g.,
https://yourwebsite.com/images/thumbnail.jpg) into the tool. - Check the Live Previews: Look at the visual previews generated below. We simulate the exact rendering engines used by Facebook, X (formerly Twitter), and LinkedIn.
- Notice how Twitter puts the URL at the bottom left, while LinkedIn puts it at the top?
- Notice how Facebook truncates descriptions differently than LinkedIn? This allows you to tweak your text until it fits perfectly across all three ecosystems without getting cut off.
- Copy the Code: Once you love how your cards look, scroll down to the dark code box. Click “Copy HTML”. We have automatically generated the flawless
<meta>tags required for both standard Open Graph and Twitter Cards. - Paste and Publish: Paste that code block into the
<head>of your webpage. You’re done!
Stop Guessing What Your Links Look Like
Hey there! We’ve all been there. You spend forty hours writing the most incredible, well-researched blog post. You hit publish, grab the URL, and excitedly paste it into a LinkedIn post or a Slack channel to show your friends.
And then… disappointment.
Instead of a massive, eye-catching image with a punchy headline, the app just spits out a plain blue hyperlink. Or worse, it randomly grabs your website’s tiny logo, crops it horribly, and uses your boring navigation menu text as the description.
In a world where people scroll at lightspeed, a bad link preview is a death sentence for your Click-Through Rate. If your link doesn’t visually pop, nobody is stopping to click it.
That is exactly why we built the OG Image & Tag Preview Simulator. We want to take the guesswork out of social sharing. Before you ever share a link publicly, you can use this tool to see exactly how it will look on the biggest platforms on the internet, and generate the bulletproof code needed to make it look perfect.
The Magic of Open Graph
The technology that powers those beautiful link cards is called “Open Graph” (often abbreviated to OG). It’s a protocol originally invented by Facebook, but it was so good that practically every platform on the internet adopted it. Twitter, LinkedIn, Slack, Discord, iMessage, WhatsApp—they all rely on Open Graph tags.
These tags live in the invisible <head> section of your website. They explicitly tell social networks:
- “Hey, use this specific image.”
- “Use this punchy title.”
- “Use this specific description.”
When you take control of these tags, you take control of your marketing. You can write a totally different headline for your social media audience than the one you use for Google Search.

The “Summary Card with Large Image” Secret
If you take nothing else away from this guide, remember this: Always force a large image card on Twitter.
By default, if you don’t specify what kind of card you want, Twitter might just show a tiny square thumbnail next to your text. That tiny thumbnail is incredibly easy to scroll past.
Our generator automatically includes the code name="twitter:card" content="summary_large_image". This line of code is pure gold. It forces X to take your image and stretch it out into a massive, edge-to-edge billboard right in the middle of the user’s feed. It commands attention.
Pair that with a high-contrast image (using bright colors like yellow or neon blue) and bold, readable text physically drawn onto the image itself, and your Click-Through Rate will skyrocket. Happy sharing!
