Convert PowerPoint to image with Nutrient Document Web Services API on Zapier

In this tutorial, you’ll learn how to convert PowerPoint presentations into images using the Nutrient Document Web Services API on Zapier. You’ll trigger the workflow when a PPT or PPTX file is uploaded to Google Drive and automatically convert it into high-resolution images.

What is Zapier?

Zapier(opens in a new tab) 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 automate PowerPoint-to-image conversion using Nutrient’s API.

What is Nutrient DWS Processor API?

Nutrient Document Web Services API is a powerful platform for document automation. With your free account(opens in a new tab), you get 50 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

What you’ll need

A Zapier(opens in a new tab) account (a pro plan is necessary for multistep Zaps)
A Google Drive account
A PowerPoint file (PPT or PPTX) stored in Google Drive
A Nutrient DWS Processor API key — sign up here(opens in a new tab)
