Key concepts
The OG image generator quickly makes Open Graph images for KakaoTalk, Facebook, and Slack link previews. Size is fixed at the recommended 1200×630. There is no logo upload or font-file picker—only background color and two lines of text. The canvas renders in the browser only.
Put the URL of this PNG on your site into the og:image meta tag. Long titles may clip, so keep core words only. Twitter large cards often use the same ratio. If you need a photo background, design it elsewhere and use this screen for text-style cards.
Example
Put the post title in Title, the site name in Subtitle, and press Preview for a dark card with white type. Host the PNG on a static path and fill og:image in a meta-tag generator to connect share previews. Keep the title short enough for one line and put the site or date in the subtitle so the card is readable. Low contrast buries type in messenger thumbnails—check contrast in Preview. Some platforms blank the card if the PNG URL is not https. When retrying the same inputs, reset first so old output is not mixed in. On a shared computer, clear the fields when you finish so the original text is not left on screen. Closing the tab drops the values; you do not need to send a delete request to a server. Button names and field labels match the tool at the top of the page, so you can follow the copy as you go.
