The Nitro connector for Zapier brings Nitro Automate’s document processing and eSignature capabilities to the apps you already connect with Zapier, with no code required. Pick up a file from Google Drive, Dropbox, Box, or an email attachment, run it through Nitro, and send the result wherever the rest of your Zap goes — no HTTP requests, no token handling.
This section documents the Nitro PDF Services app in the Zapier app directory. If you cannot add it to a Zap yet, ask your Nitro contact for an invite link.eSignature steps come from the separate Nitro Sign app on Zapier.

What you can do

Conversions

Convert between PDF and Office formats (Word, Excel, PowerPoint) in either direction, plus images, CSV, XML and HTML to PDF and PDF to PDF/A for archiving.

Document generation

Fill PDF forms with data from your Zap or a data file, or turn a flat PDF into a fillable form automatically.

Data extraction

Extract text, tables, invoice data, form fields and metadata from documents and pass them to downstream apps.

Document manipulation

Merge, split, compress, optimize, OCR, rotate, flatten and watermark PDFs as a step in any Zap.

End-to-end eSignatures

Send signature requests from a template and act on completed signatures with the Nitro Sign app.

Security and compliance

Password-protect documents, manage permissions and redact sensitive data to keep your Zaps compliant.

Keep documents moving

Start document processing automatically from events in any connected app, such as a new file in Google Drive, a form submission, or a deal update in your CRM.

​
Typical Zaps people build with it

  • A new invoice is added to Google Drive → Parse Invoice → add a row to Google Sheets or Airtable.
  • A Typeform response is submitted → Fill PDF Form → send the completed form for signature with Nitro Sign.
  • A HubSpot or Salesforce deal moves to closed-won → send for signature with Nitro Sign → post a Slack notification when it is signed.
  • An email with an attachment arrives in Gmail → Smart PII Detection → Redact PDF → save the redacted copy to Dropbox.
  • A report is uploaded to OneDrive → Microsoft Office to PDF → Password Protect PDF → email it to the client.

How it works

Connecting to Nitro

The first time you add a Nitro step to a Zap, Zapier asks you to connect your Nitro account. Enter the Client ID and Client Secret from your API application, and optionally a connection name. The connection is saved to your Zapier account and can be reused across Zaps; the app obtains and refreshes access tokens for you.
Nitro actions accept files from earlier steps in your Zap — a file object or a file URL — and return the processed file for the next step to use, including another Nitro action. Files up to 100 MB and 500 pages are supported.
The PDF Services app provides actions only. There are no triggers or searches, so a Zap always starts with another app’s trigger and uses Nitro as a subsequent step. The Nitro Sign app adds a signature request completed trigger.

​
