OG Image Maker

Free tool for link preview images

•

An Open Graph image (OG image) is the preview image people see when your link is shared on Twitter/X, Facebook, LinkedIn, Discord, Slack, iMessage, or in Google search snippets. It's the single biggest factor in whether someone clicks. A well-designed OG image can lift click-through rates by 40-100% versus a generic screenshot or no image at all.

The standard size is 1200×630 pixels. This works on every major platform without cropping. Twitter prefers 1200×628 and Threads 1200×600 — close enough that the same asset usually works. File size should stay under 5MB; 200-500KB is ideal so previews load instantly. PNG is best for graphics with text, JPEG for photographic content, WebP for both with smaller file sizes (modern platforms support it).

This tool runs entirely in your browser. Pick a size, type your title and subtitle, drop in a logo, choose a background (solid color, gradient preset, or upload your own image), and download. Settings are saved to your local storage so you can iterate over multiple sessions. Nothing is uploaded anywhere.

How to Use This Generator

  1. Pick a size: use one of the platform presets (Twitter, Facebook, LinkedIn, Discord, Threads, Telegram) or enter custom dimensions.
  2. Set the background: solid color, one of 8 gradient presets, custom gradient with direction picker, or upload your own image.
  3. Add your text: title and optional subtitle. Pick fonts, sizes, colors (solid or gradient), and shadows.
  4. Add your logo (optional): upload PNG/SVG/JPG, scale it, position it relative to the text (above, left, or right).
  5. Polish with overlays and borders: dot patterns, grid, lines, drop shadows, or framed borders.
  6. Export: click Download to save as PNG, JPEG, or WebP. Click Copy to put the image directly on your clipboard.

Pro Tips

  • Test before publishing: drop your URL into opengraph.xyz, Facebook's Sharing Debugger, or Twitter Card Validator. Cache stale OG images aggressively, so refresh after each change.
  • Keep titles short: Twitter and Slack truncate around 60-70 characters. Facebook and LinkedIn allow more, but the first 4-5 words do most of the work.
  • High contrast wins: social feeds compress images aggressively. Light text on a dark gradient or dark text on a bright background reads better than subtle two-tone designs.
  • Use absolute URLs: always reference OG images with the full https://yoursite.com/path.png URL. Relative paths break in scrapers.
  • Set width and height in meta: add og:image:width and og:image:height tags so platforms reserve the right space and don't stretch the image.

Frequently Asked Questions

What is an OG image?
An OG (Open Graph) image is the preview image that appears when you share a link on social media platforms like Twitter/X, Facebook, LinkedIn, Discord, and Threads. It's defined using the og:image meta tag in your HTML.
Where do OG images appear?
OG images show up in link previews on social media feeds, messaging apps (Slack, Discord, iMessage), and search engine results. They're the first visual impression people get of your content before clicking.
What size should my OG image be?
The recommended size is 1200×630 pixels, which works well across most platforms. Twitter/X uses 1200×628, LinkedIn uses 1200×627, and Threads prefers 1200×600. Use PNG or JPG under 5MB.
How do I add an OG image to my website?
Add this meta tag in your HTML : . Also add og:title and og:description for complete previews. Use absolute URLs, not relative paths.
Why isn't my OG image showing?
Common issues: using relative URLs instead of absolute, image file too large (>5MB), incorrect meta tag syntax, or cached old data. Use Facebook's Sharing Debugger or Twitter Card Validator to test and refresh cache.
Does this tool save my work?
Yes. Your settings are saved automatically to your browser's local storage so they survive a page reload. Click the Reset button to clear them. Nothing is sent to any server — all rendering happens locally in your browser.
