Frequently Asked Questions — OG Image Generator
What is an OG image?
An OG (Open Graph) image is the preview image shown when you share a link on social media platforms like Facebook, Twitter/X, LinkedIn, or messaging apps. It's specified using the og:image meta tag in your HTML and should be 1200×630 pixels for best results.
Is the OG image generator free?
Yes, completely free. No registration, no hidden charges, and no watermarks. All processing happens locally in your browser.
What is the recommended image size?
The standard OG image size is 1200×630 pixels (a 1.91:1 aspect ratio). Our tool generates images at exactly this resolution, which is optimized for Facebook, Twitter/X, LinkedIn, and most other platforms.
How do I use the generated OG image?
Download the PNG image, upload it to your website, and add the following meta tags to your HTML <head> section: <meta property="og:image" content="URL_TO_YOUR_IMAGE"> and <meta property="og:image:width" content="1200"> <meta property="og:image:height" content="630">.
Can I use a custom background image?
Yes! You can upload any image as the background. The tool will automatically scale and center it to fit the 1200×630px canvas. Images with good contrast work best for text readability.
Do OG images affect SEO?
While OG images don't directly impact search rankings, they significantly improve click-through rates from social media shares. Higher engagement on social platforms indirectly benefits your SEO by driving more traffic to your content.
What font is used in the generated image?
The tool uses the system's default sans-serif font for text rendering. This ensures compatibility and reliable text display across all devices. The text is rendered directly onto the canvas, so the final image looks the same everywhere regardless of installed fonts.
