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.
Source code for this example on CodePen.
Remote Stories Social Cards

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, use query params to adjust to any size you need with the width and height params. When only one param is passed, the API will maintain the aspect ratio of the original image.
?width=400
?height=300
