HTMLCSStoImage generates images but can't deliver them. cloudlayer.io generates images AND PDFs with webhooks, S3, and GCS delivery built in.

HTMLCSStoImage generates images but has no webhooks, no S3 forwarding, and no GCS integration. You have to download and distribute files yourself.
While HTMLCSStoImage can output PDFs, it's designed as an image API. cloudlayer.io treats both PDFs and images as first-class outputs.
HTMLCSStoImage has limited SDK coverage. cloudlayer.io offers SDKs for Node.js, Python, PHP, Ruby, Go, Java, C#, and F#.
Create your cloudlayer.io account and get an API key in under a minute. No credit card required. Full API access from day one.
Bring your existing HTML templates or build new ones with the visual editor or Nunjucks. Upload fonts and assets to our CDN.
Swap the HTMLCSStoImage endpoint with cloudlayer.io. Our REST API accepts HTML, template IDs, or URLs — most migrations take minutes.
Generate both PDFs and images from the same templates. One API, one account, one integration for all your document needs.
Webhook notifications, direct S3/GCS upload, CDN-hosted URLs, and base64 responses. Documents go where they need to go.
SDKs for Node.js, Python, PHP, Ruby, Go, Java, C#, and F#. Install from your package manager and start generating.
