Social Preview Image

Create a 1200x630 Open Graph preview image from a headline, free.

Runs entirely in your browser — nothing is uploaded.

About the Social Preview Image

The Freemium.Tools social image generator creates a 1200×630 Open Graph preview image — or a square, story or banner version — from a headline and subtitle, rendered in your browser.

A link shared without a preview image is far easier to scroll past. Generating one takes a headline, an optional supporting line and a colour theme, and produces a crisp PNG at exactly the size Facebook, LinkedIn, X and Slack expect.

Because the image is drawn on a canvas in your browser, there is no design tool to learn, no watermark and no upload — the PNG downloads straight to your device.

How to use it

  1. 1Write the headline. The main line people will see; it wraps automatically.
  2. 2Choose a look. Pick a colour theme and the size you need — social preview, square, story or banner.
  3. 3Download the PNG. Save it and set it as your og:image, or post it directly.

Frequently asked questions

What size should an Open Graph image be?

1200 by 630 pixels is the standard, giving the 1.91:1 ratio that Facebook, LinkedIn, X and Slack all crop to cleanly.

Where do I put the finished image?

Upload it to your site, then reference it in an og:image meta tag with an absolute https URL. Our meta tag generator writes the tag for you.

Is there a watermark?

The image carries a small freemium.tools line in the corner, in keeping with the free tool. Everything else is yours.

Is anything uploaded?

No. The image is drawn on a canvas in your browser and downloaded straight from there.

Why is my preview not updating after I change the image?

Social networks cache previews aggressively. Use the platform's own debugger or sharing validator to force a refresh.
