I shared my invitation link on KakaoTalk but no thumbnail shows.

Usually one of: (1) the OG image URL is not HTTPS, (2) the image is too large, or (3) KakaoTalk has cached an old empty page. Click "Re-scrape" in the Kakao Debugger to force a refresh.

The image looks cropped.

KakaoTalk crops the standard 1200×630 OG image at a 1.9:1 ratio. Place important text in the center, or prepare an 800×400 version.

How do I use the OG image generated here on my own wedding invitation?

Upload the generated PNG to a hosting service (Imgur, GitHub Pages, your own server), then set that URL as the og:image tag. Use the "Copy Meta Tags" button to get the full snippet.

Does this work with HappyMillie, Oply, or other invitation platforms?

Those platforms generate their own OG. This tool is designed for self-hosted wedding invitations or for downloading card images.

Korean fonts look broken in the OG image.

This tool automatically applies Pretendard and Apple SD Gothic Neo. If you use your own template, font embedding is required.

Do you support the 1080×1080 square for Instagram Stories?

Yes. Select "Square 1080×1080" in the download section to get the OG image for Stories or feed posts.

How do I get a large image on X (Twitter)?

Add ` `. It is already included in the meta tag code generated by this tool.

Can I paste a URL and have the OG auto-loaded?

Due to CORS restrictions, the client cannot directly read arbitrary URLs' HTML. The MVP supports generation mode only. A serverless function may be added in the future.

Is my personal information stored?

No. All input is stored only in the browser's localStorage and never sent to a server. OG image generation also runs entirely locally via the Canvas API.

I also want to generate a payment (cash gift) link.

A separate tool — Wedding Invitation QR Bank Transfer Generator — is planned. This tool is specialized for OG thumbnail optimization.
