Convert HTML files to images with Nutrient Document Web Services API on Zapier

What is Zapier?

Zapier is an automation platform that connects your favorite apps and services with no code required. You can build “Zaps” to automate repetitive tasks by setting up triggers and actions between apps like Google Drive, Slack, Gmail, and more.

In this tutorial, you’ll learn how to use Zapier to automatically convert HTML files into JPG, PNG, or TIFF images using the Nutrient API.

What is the Nutrient API?

Nutrient Document Web Services API is a powerful platform for document automation. With your free account, you get 100 credits, which you can use to perform various document operations. Each tool (e.g. conversion, signing, flattening) consumes a different amount of credits depending on complexity.

Nutrient offers more than 30 tools with the ability to:

• Convert images and documents to PDF

• Merge, split, or reorder pages

• Add digital signatures, watermarks, or annotations

• Run OCR, redact, flatten, and more

All you need is an API key from a free account to get started. You can chain these tools together in Zapier to build powerful, automated PDF workflows.

What you’ll need

• A Zapier account (a pro plan is necessary for multi-step Zaps)

• A Google Drive account

• A public HTML file stored in Google Drive

• A Nutrient Document Web Services API key — sign up here

Step 1 — Trigger a new file in a Google Drive folder

1. Select Google Drive as the trigger app.

2. Choose the New File in Folder trigger event.

3. Connect your Google Drive account.

4. Choose your drive and specify the folder containing your HTML files.

• Ensure that the option for Include Deleted Files? is set to Only return non-deleted files.

5. Test the trigger to confirm Zapier can detect the HTML file. You can use our sample file for testing this step.

Step 2 — Convert HTML to image action (Nutrient API)

1. Next, select Nutrient Document Web Services API as the app.

2. Choose the Convert HTML to Image action.

3. Connect your Nutrient API account using your API key.

You can find your API key in the Nutrient dashboard.

4. Fill in the required fields:

• HTML file — Choose the file from the Google Drive trigger.

• Output Format — Select from jpg, png, or tiff.

• Output File Name — Optional — Choose a file, e.g. web-preview.jpg.

5. Test the action step to confirm the conversion.

Step 3 — Upload the updated PDF to Google Drive

1. Now, add another step by selecting Google Drive as the app and Upload File as the action event. Connect your Google Drive account if needed.

2. Map the output from the previous step and select your target folder.

3. Test the Zap to confirm the image is saved in Google Drive.

Conclusion

With this workflow, you’ve automated the process of turning HTML files into image files using Zapier and the Nutrient API. This setup is ideal for visual snapshots of web content, HTML templates, or stored previews. Extend the flow by adding steps like emailing the image, compressing it, or organizing it in folders based on source.
