Upload an image, enter an image URL, or render SVG and HTML/CSS code to compare link card layouts across KakaoTalk, Facebook, X, Threads, LinkedIn, Naver Blog, and Notion. Spot image cropping and truncated titles or descriptions before you publish: everything runs in your browser.
Uploaded images and entered content are not sent to or stored on a server. All previews are processed in your browser.
Platform previews simulate common link card layouts. Actual results may vary by app version, device, and cache status.

Share the same URL and it looks different in KakaoTalk, X, LinkedIn, Naver Blog and Notion. Image ratios differ, the number of title lines differs, and some services cut the description to a single line or push the image into a small thumbnail on the right. So OG tags tuned to look good in one place routinely end up with a title truncated mid-phrase somewhere else.
This tool exists to put a title, description, image and domain in one place and flip between platforms to see those differences. Checking before you ship lets you tune the copy against the tightest layout rather than discovering it after the fact.
For images, 1200×630 (1.91:1) is the safest default. X crops closer to 2:1 and Naver Blog closer to a square, so any critical text or logo belongs in a central safe area rather than near the edges, where it survives either crop.
Titles generally get two lines, but on narrow cards they break somewhere around 40 characters. Descriptions are cut to one line on X, Threads and LinkedIn, so lead with the point and put elaboration after it. Repeating the brand name up front means the actual content is what gets truncated.
This is a simulation of each platform's layout rules. Real cards are built by the platform crawling your URL, which is why an old image often keeps appearing after you have already fixed the tags: most platforms cache OG data.
The fix is to refresh the cache in that platform's own debugger, such as the Facebook Sharing Debugger, the X Card Validator, or Kakao's developer tools. Pages behind a login, or blocked from crawlers in robots.txt, will not produce a card at all.
Leading with the brand name means the brand name is all that survives truncation. Putting the page subject first and the brand last is safer.
A logo tucked into a corner disappears on one of them. Keep anything important within the central 60%.
Anything essential placed in the second sentence is invisible on major platforms.
What it is, who it's for, how it works and why you'd use it.
The Open Graph Preview Tester simulates how an image and metadata text may appear in link cards across major platforms.
It is designed for product managers, designers, and developers reviewing social sharing assets.
The tool accepts an uploaded image, a direct image URL, or SVG and HTML/CSS code, then applies the content to platform-specific preview layouts.
It helps identify image cropping, low resolution, and truncated titles or descriptions before a page is published.
