Practical guide
How to create an Open Graph image that travels well
An Open Graph image is the visual asset referenced by a page’s og:image tag and used by many social networks, messaging apps, and link unfurlers. A clear 1200×630 image helps people recognize the topic, but it does not replace descriptive HTML or structured data.
Campaign sharing
Prepare a large link-card image for launches, guides, reports, and evergreen resources.
Platform variants
Export alternate aspect ratios for X posts or square social placements from the same editor.

Common questions
Frequently asked questions
What is an Open Graph image?
An Open Graph image is the image referenced by a page’s og:image metadata. Social networks and messaging apps can use it when someone shares the page.
What size should an OG image be?
1200×630 pixels, an aspect ratio of about 1.91:1, is a widely supported starting point for large link previews on Facebook, LinkedIn, and other platforms.
Should I export PNG, JPEG, or WebP?
PNG is a safe default for graphics and text. JPEG is often smaller for photo-heavy designs. WebP can reduce file size, but PNG or JPEG remains the more conservative choice for broad social crawler compatibility.
Are my images uploaded to Blogima?
No. The editor processes source images in your browser. Your draft can be stored in browser storage so it is available when you return on the same device.
Does text inside an OG image help AI SEO?
The image can improve recognition and social click-through, but text inside a raster image is not a substitute for crawlable HTML. Put the same core topic and context in the page title, headings, body, and appropriate metadata.
