The OG Image Generator creates Open Graph preview images sized at 1200×630 pixels — the recommended dimension for Facebook, Twitter, LinkedIn, and other social platforms. When someone shares a link, the platform pulls the og:image to display a visual card alongside the title and description. A compelling preview image dramatically increases click-through rates. Instead of opening a graphics editor, simply type your title and subtitle, preview the result in real time, and download a high-quality PNG. The entire process runs in your browser using HTML Canvas — no uploads, no server processing, and no design skills required.
About OG Image Generator
Open Graph images are the visual cards that appear when you share a link on social media. Facebook, Twitter, LinkedIn, Slack, Discord, and many messaging apps all read the og:image meta tag to decide what image to display. The recommended resolution is 1200×630 pixels, which provides crisp rendering on both desktop and mobile. This tool generates a clean, professional card with your custom title and subtitle text, making it ideal for blog posts, landing pages, product announcements, or any page you want to look great when shared.
How to Use OG Image Generator
- Enter a Title — this is the main headline that appears on the preview card.
- Optionally add a Subtitle for additional context (e.g. your site name or a tagline).
- Preview the generated 1200×630 image in real time below the form.
- Click the download button to save the image as a PNG file.

Technical Details
The image is rendered on an HTML5 <canvas> element at 1200×630 pixels. The title and subtitle are drawn with web-safe fonts, centered and scaled to fit. The finished canvas is exported as a PNG using canvas.toDataURL() and offered as a download. Because all rendering happens in the browser, your text is never transmitted to any server. For best social media results, host the downloaded image at a publicly accessible URL and reference it via the og:image meta tag with an absolute URL.
