CldOgImage Configuration
The CldOgImage component is built on top of the same APIs used for CldImage, giving you the ability to apply the same transformations to your social cards as you can any image.
See CldImage for all image transformations.
General Props
Prop Name | Type | Example |
---|---|---|
alt | string | "Svelte Cloudinary" |
excludeTags | array | ['twitter:title'] |
keys | object | {'og:image': 'my-og-image'} |
twitterTitle | string | "Svelte Cloudinary" |
Image Size
By default, the image canvas is based upon 2400x1254, but resized down to 1200x627, meaning, you can design the image as if it were a 2400x1254 image, but the resulting image will be sized down to 1200x627 to avoid an overly large image.
627 (with a canvas of 1254) is used to satisfy the 1.91:1 ratio requirement and minimum size requirement from linkedin.
The resizing mechanism provides backwards compatibility for existing usage as well as a way to maintain a consistent “canvas” size when designing a social image card.
You can use the width
and the height
to control the canvas and widthResize
to change the final size the image is scaled to.
The height is ultimately calculated using the width
value and the widthResize
values to maintain the correct ratio.
Image Format
While Cloudinary’s f_auto
parameter (format of auto) is great for websites and mobile apps, having more control over the format helps to reduce initial encoding time, which is more critical for a social network to recognize the image and load it on first share.
The default format for most use cases is then jpg, as webp does not have broad support (likely nor does AVIF).

However, Twitter does support webp, so we’re able to customize the format using the Twitter specific tag, and generally a separate webp version for that platform to optimize where we can.
Excluding Tags
The summary_large_image
Twitter card type requires the inclusion of a twitter:title
card. Because of this, the component includes it by default for simplified use along with a prop to change the value.
To exclude this tag to manage it on your own, use the excludeTags
prop:
excludeTags={['twitter:title']}
Keys
By default, CldOgImage includes static keys on each meta tag rendered to help avoid duplication in the DOM.
To allow customization and control in the event you want to minimize duplication with existing meta tags, you can specify custom keys for each tag.
For instance, by default og:image
tag will effectively render with:
<meta key="og-image" property="og:image" content="..." />
Where if you pass in the keys
prop with the following:
keys={{'og:image': 'my-og-image'}}
The tag will render with:
<meta key="my-og-image" property="og:image" content="..." />
