HTML/CSS to Image integration

Create Image

Create a hosted image from HTML/CSS or an internet-reachable webpage, including authenticated pages using request headers. Use GET_IMAGE afterward to download, resize, crop, or convert it.

Create Image from Template

Create an image from a reusable template using the latest version or an explicitly selected version.

Create Images Batch

Create 1 to 25 hosted images from HTML/CSS or internet-reachable webpages in one request, including authenticated pages using shared or per-image headers. Requires an account plan that supports batch creation.

Create Template

Create a reusable Handlebars HTML/CSS image template. WARNING: the template is persistent because the API exposes no delete operation, and a free account can hold only one template.

Delete Image

Permanently delete one generated image and clear its HCTI CDN cache. Copies previously written to external storage are not deleted.

Delete Images Batch

Permanently delete multiple generated images and clear their HCTI CDN caches. Copies previously written to external storage are not deleted.

Get or Transform Image

Download a generated image by ID, optionally converting its format, resizing it, or cropping it.

Get Usage

Return recent hourly, daily, monthly, and billing-period image usage for the connected account.

List Templates

List reusable image templates owned by the connected account, including their current version, source, and render settings.

Update Template

Create a new version of an existing template using replacement Handlebars HTML and optional CSS or render settings.
