Every issue you ship deserves a click-worthy social preview. Generate professional 1200×630 OG images in seconds — free, no Canva, no subscription.
Generate Your OG Image Free →No login required · Works with Substack, Beehiiv, Ghost, Kit & more
You spend two hours crafting the perfect issue — sourcing the best AI tools, writing sharp takes, structuring the sections. Then you hit publish. Your Substack or Beehiiv post goes out. On LinkedIn it renders as a grey box. On X it's a plain text link. On Slack previews it shows your newsletter's generic logo from 2022.
That blank preview is costing you clicks. Studies consistently show that social posts with rich images get 2–3× more engagement than text-only links. For newsletter writers, that means fewer referral clicks, slower subscriber growth, and lower sponsor visibility.
Generate a unique OG image for each issue with the date, issue number, and headline. Paste into Beehiiv or Substack's "cover image" field before publishing so every share looks intentional.
Running a weekly AI tool roundup? Generate a branded card per tool spotlight — tool name, one-line description, your newsletter logo. Share each card as a thread teaser on X to drive full-issue clicks.
Create sponsor-co-branded OG images with the sponsor's product name baked into the preview. LinkedIn posts with sponsor logos in the image get 40–60% more impression shares than plain-text sponsored posts.
"Just hit 10,000 subscribers!" posts without a visual get buried. Generate a celebration card with your subscriber count, newsletter name, and a bold gradient. Milestone posts with visuals convert 3× more follows from impressions.
AI newsletters that lead with data ("GPT-4o is 47% cheaper than Claude 3.5 for RAG workloads") get shared more when the stat is prominent in the OG image preview rather than buried in the body copy.
No account needed. Go to /og-image-generator/ — it loads instantly in your browser.
Paste your issue headline as the main title. Add a short tagline — your newsletter name, the issue date, or a hook like "The 5 AI tools everyone missed this week."
Enter your newsletter's primary hex color. Pick from a dark gradient, clean light, or bold full-bleed layout. Preview updates in real time.
Export as PNG at 1200×630. In Beehiiv: Settings → Post settings → Cover image. In Substack: the cover photo upload. In Ghost: the feature image field. Done — every share of your issue now shows a proper preview.
