Image Examples
Your imagination is the only limit. We render HTML/CSS just like Google Chrome. Here are a few examples of ways people have used the API to automate their image generation.
Social Images: Dev.to
Dev.to uses the API to autogenerate thousands of custom images for Twitter and Facebook.
To see how they do it, take a look at their code (it’s open source!).
Product Hunt Makers Social Cards
Product Hunt uses HTML/CSS to Image to dynamically generate social cards for Maker Goals.

Auto Generated Job Listing

Full Webpage Screenshots
Pass a URL or entire webpage to the API to generate a full page screenshot. Here we passed stripe.com’s to the API.
Screenshot part of a page
Use the selector
param to focus on a specific part of a page.
Resize on the Fly
Once an image is generated, you can adjust its size using query parameters:
- width: Set the image width (e.g.,
?width=400
) - height: Set the image height (e.g.,
?height=300
)
When only one parameter is specified, the API maintains the original aspect ratio automatically.
Example with width=400:
Example with height=300:
