What is an OG Image Generator?

An OG Image Generator is a free online tool that creates 1200x630 Open Graph images: the preview images that appear when you share a link on social media platforms like Facebook, LinkedIn, and Twitter. These images are defined by the `og:image` meta tag and play a crucial role in attracting clicks and engagement. With our generator, you can customise the title, subtitle, background, layout, and text colour, all without any design skills.

The tool works entirely in your browser: no data is uploaded, so your content stays private. Just set your text, pick a template or customise, and download a polished PNG ready for your website’s meta tags.

How to Use the OG Image Generator

Creating your own Open Graph image takes only a few steps:

  • Enter your title and subtitle: Type the text you want to appear on the image. The title is limited to 100 characters, subtitle to 140: this ensures readability.
  • Choose a template or customise: Pick a quick-start template (Bold Statement, Minimal Dark, etc.) or manually adjust background (gradient, solid, or image), layout (centered, left, or bottom), and text colour.
  • Preview live: The image updates in real time as you change settings: you see exactly what you'll get.
  • Download or copy: Click “Download” to save the PNG, or “Copy” to copy the image to your clipboard for instant pasting.
