ToolNestFree OG Image Generator
Last updated: October 19, 2026
Quick answer: When you share a link on Facebook, X, or LinkedIn, the platform shows a preview card — and the image on that card is the OG image (1200×630 pixels). Links with a custom preview image get far more clicks than the same link with a blank gray box. This free OG image generator designs that card right in your browser: type your headline, pick a template and colors, and download a pixel-perfect 1200×630 PNG to use as your og:image. No signup, nothing uploads — the image is drawn on a canvas in your browser.

Common Use Cases
- Blog posts: Give every article a branded preview card instead of the platform's auto-grabbed (often ugly) first image.
- Landing pages: Keep OG images consistent across campaigns so every shared link looks deliberate and on-brand.
- Newsletters: Reuse the 1200×630 card as the newsletter header image — one design, two jobs.
- Product launches: Announcement graphics at exactly the right size, made in a minute with no design tool.
- Fixing blank link previews: Replace the gray 'no image' box with a real card — the fastest CTR win in social sharing.
- Podcast episodes: One card template per show, swapped headline per episode — consistent art across the whole feed.
- YouTube thumbnails: Repurpose the card as a thumbnail base: the same headline-first layout works at 1280×720.
- Real estate listings: Branded property cards with the listing address and price baked in, ready to share anywhere.
OG Image Generator vs Alternatives
- Canva / Figma: Powerful design tools — but overkill for one card: accounts, template hunting, and export steps for a 60-second job.
- SaaS OG-image generators: Many put the good templates behind a signup wall, add watermarks, or cap free exports per month.
- Vercel og-image / code libraries: Excellent for developers — but they require code, hosting, and deployment for what is often a one-off image.
- Photoshop: The professional choice, and a paid subscription plus real skill for a single 1200×630 card.
- WordPress SEO plugins (Yoast / Rank Math): Auto-generate a basic card from your post title and featured image — fast, but generic-looking and limited styling control.
- GitHub repo social preview: GitHub makes a repo card automatically; for everything outside GitHub you still need your own 1200×630 image.
If you need a full design system, Canva or Figma is the right call. For a fast, free 1200×630 preview card with no account and no watermark, this page does it in under a minute.
Frequently Asked Questions
What size should an OG image be?
1200×630 pixels (a 1.91:1 ratio) — that is the size Facebook recommends, and X and LinkedIn both display it cleanly. Smaller images get upscaled and look blurry; larger ones just waste bytes.
Where do OG images appear?
On link preview cards everywhere links are shared: Facebook, X (Twitter), LinkedIn, Slack, Discord, iMessage, and WhatsApp. The og:image tag in your page's HTML tells each platform which image to show.
What is the difference between og:image and twitter:image?
twitter:image overrides the preview specifically on X; when it is absent, X falls back to og:image. One 1200×630 PNG set as og:image covers both — add twitter:image only if you want X to show something different.
Why is my link preview blank or showing the wrong image?
Platforms cache the first scrape of your URL. After adding or changing og:image, force a re-scrape with the Facebook Sharing Debugger or the X Card Validator. Also check that the og:image URL is absolute (https://…) — relative URLs silently fail.
Do OG images affect SEO rankings?
Not directly — Google does not rank pages on their OG image. But a good preview card raises click-through from social shares, and that traffic and the links it earns absolutely help.
What file format should the OG image be?
PNG for text-heavy cards (crisp letters), JPG for photographic cards (smaller file). Keep it under ~1 MB for fast loads — most platforms accept up to 8 MB, but smaller previews load and cache faster.
How do I add an og:image tag to my page?
Put this inside the <head> of your page, before the closing </head>: <meta property="og:image" content="https://yoursite.com/card.png" />. The URL must be absolute (full https:// address) — relative paths silently fail on most platforms.
Why is my X (Twitter) preview tiny even with an og:image?
X only renders the large card if you also set <meta name="twitter:card" content="summary_large_image" />. Without it, X falls back to a small thumbnail next to the text. Add that one line alongside your og:image tag.
Is there a text safe zone for OG images?
Yes — keep your headline and any important text inside the central ~1100×520 area. Facebook, X, and LinkedIn each crop the card slightly differently on mobile, so text near the edges can get clipped on some devices.
Should every page have its own OG image, or one for the whole site?
Per-page cards win. A card with the article's actual headline gets far more clicks than a generic site logo. Use one default sitewide image as a fallback, then set a custom og:image on every important page.
How do I preview my OG image before publishing?
Paste the page URL into the Facebook Sharing Debugger, LinkedIn Post Inspector, or X Card Validator — each shows exactly what the card will look like and lets you force a fresh re-scrape after you change the image.
What is the og:image:alt tag?
It gives screen readers and some platforms a text alternative for the preview image: <meta property="og:image:alt" content="Short description of the card" />. Good practice for accessibility, and it takes ten seconds to add.
