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

Source code for this example on CodePen.

Highlighted Text Shots

Generate images from your users comments. Add the ability to highlight and share.

Source code for this example on CodePen.

Auto Generated Job Listing

Generate images from job listings for sharing in emails, ads or social media.

Source code for this example on CodePen.

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:
