OGP Image Simulator

Preview how a title, description, and image will look as a shared link card before you publish.

Preview:
Add an image URL or upload a local image to preview the crop.
example.com · Facebook
A clear headline that describes the page
A short, compelling summary that gives readers a reason to click through and learn more.

Large-card crop simulation: 1200×630. Recommended source image: 1200×630. Actual previews vary by app, device, and cache.

Character counts: title 40/40, description 88/88. Social platforms may crop or truncate text differently; check each tab before publishing.

Automated checks

  • og:title is present — Pass
  • Title is 60 characters or fewer — Pass
  • og:description is present — Pass
  • Description is 160 characters or fewer — Pass
  • og:image is set — Fail
  • Image URL is an absolute HTTPS URL — Check
  • Image loads successfully — Check
  • Image is at least 1200×630 — Check
  • Image aspect ratio is about 1.91:1 — Check
  • Image file size is under 5 MB — Check
  • og:image:alt is present — Fail
  • og:site_name is present — Pass
  • og:url is an absolute HTTPS URL — Pass

What to fix

• Add an og:image — most platforms show no large card without one.

• Use the full https:// URL of the published image; relative or http:// image URLs are ignored by several platforms.

• Waiting for the image to load so its size can be checked.

• Load the image to check its dimensions.

• Load the image to check its aspect ratio.

• File size could not be read (the host may block cross-origin reads) — verify it is under 5 MB where the image is hosted.

• Add og:image:alt describing the image for screen readers and as a fallback caption.

Copy-ready fixed tags

How to use it

  1. Load sample data, type your card fields, or fetch a public page's tags.
  2. Choose a public image URL or test a local image without uploading it.
  3. Switch platform tabs and review cropping, dimensions, and text-length guidance.
What is OGP Image Simulator?

Preview how a title, description, and image will look as a shared social link card.

How it works

Enter social-card fields, load sample data, or explicitly fetch tags from a public URL. Preview common platform crops and inspect the source dimensions. Local image uploads use a browser object URL and are never uploaded; URL fetching uses SiteIndex's existing page-metadata service.

Common uses
  • Check whether a title or description gets truncated in a preview card.
  • Preview an OG image's crop and framing before publishing.
  • Compare a few title/description variations for a shared link.
Limitations
  • Results depend on the browser, network, input, and external service involved.
  • This tool is informational and does not replace specialist diagnostics or professional advice.
Frequently asked questions
Does this fetch the live page?
Only when you enter a public URL and choose Fetch page tags. Typed fields and local image previews do not require a page fetch.
Are local image files uploaded?
No. A local image is displayed using an object URL in your browser. No image-upload request is made.
What source image size should I use?
1200×630 is a common starting point. Check each simulated crop and test on the target platform because actual rendering varies.
