Nitro PDF Services (Preview)

The Nitro PDF Services connectors provide end-to-end PDF and document processing: converting between formats (PDF, Word, Excel, images, HTML), compressing, merging, splitting, and editing files (rotate, delete pages, protect/unprotect, flatten, redact). They also extract structured data and insights from PDFs - text, tables, metadata, form data, and PII with locations - while supporting secure API access and document property management.

This connector is available in the following products and regions:

Nitro PDF Services Connector

Overview

The Nitro PDF Services connectors provide end-to-end PDF and document processing: converting between formats (PDF, Word, Excel, images, HTML), compressing, merging, splitting, and editing files (rotate, delete pages, protect/unprotect, flatten, redact). They also extract structured data and insights from PDFs—text, tables, metadata, form data, and PII with locations—while supporting secure API access and document property management.

Publisher: Nitro Software

Prerequisites

To use Nitro PDF Services through this connector, you will need:

Authentication

Nitro PDF Services uses machine‑to‑machine OAuth 2.0 with the Client Credentials grant to generate access tokens for API requests.

How it works

  • You create an API application in Nitro’s self‑service portal and obtain the associated Client ID and Client Secret.
  • The connector authenticates by exchanging these credentials for a Bearer access token.
  • The token is then used to authorize subsequent Nitro PDF Services API calls.

Create credentials & read the detailed guide:
https://developers.gonitro.com/docs/authentication/credentials

Creating a connection in Power Automate / Power Apps

When adding the connector to a flow or app:

  1. Click Add a new connection.
  2. Enter your Client ID and Client Secret (issued in the Nitro developer portal).
  3. Save the connection — on first use, the connector exchanges your Client ID and Client Secret for a short-lived access token using the OAuth 2.0 Client Credentials grant, caches it, and renews it automatically. Your credentials are only used to obtain the token; subsequent API calls are authenticated with a bearer token on your behalf.

Note: No user-interactive sign-in is required; this flow is designed for server-to-server / app-to-app scenarios.

Supported Operations

1. Conversions

Convert between PDF and other document formats.

PDF to MS Office

  • PDF to Word
  • PDF to Excel

MS Office to PDF

  • Word to PDF
  • Excel to PDF
  • PowerPoint to PDF

Image to PDF

Convert common image formats (JPG, PNG, TIFF, etc.) into PDF.

PDF to Image

Convert PDF pages into various image formats.

HTML to PDF

Convert HTML content into PDF.

Output format:
Conversions return either JSON or binary output depending on the Accept header (default: application/octet-stream).

2. Transformations

Operations that modify or restructure PDF documents.

  • Compress PDF
    Reduce file size using compression levels.

  • Flatten PDF
    Convert interactive or layered content into static, non-editable elements. This process is irreversible.

  • Rotate PDF pages
    Rotate one or more pages using a rotation array (page index + angle).

  • Delete PDF pages
    Remove pages by index.

  • Split PDF document
    Split a multi-page PDF into multiple PDFs based on custom page ranges.

  • Merge PDF documents
    Combine multiple PDFs into a single document.

  • Redact PDF pages
    Add redaction boxes to hide sensitive content.

  • Set PDF properties
    Update standard PDF metadata fields.

  • Password protect PDF
    Add password protection and access permissions.

  • Unprotect PDF
    Remove passwords and restrictions.

Output format:
Transformations can return JSON or binary output depending on the Accept header.

3. Extractions

Retrieve structured or unstructured data from PDF documents.

Extract PDF Form Data

Automatically extracts all form field values.

Extract PDF Table Data

Identifies and returns table data from PDF files.

Extract Text from PDF

Extract text:

  • from the full document, or
  • from specific pages via the pageIndices parameter.

Additional optional params field: readingOrder (boolean, default false) — when true, reorders extracted text to match the visual reading flow (useful for multi-column layouts). Output quality varies by document: works best on well-tagged PDFs; on dense multi-column designs it can interleave sentences from adjacent columns.

Extract PII Location from PDF

Find bounding boxes for specific text values.
Input: list of strings (texts)
Output: bounding boxes containing those strings.

Extract PII from PDF

Extract Personal Identifiable Information (PII) bounding boxes from form fields.
Supports:

  • English
  • Spanish

Extract Properties from PDF

Extract PDF metadata properties.

Output format:
Extractions return JSON only.

Errors & Throttling

The Nitro PDF Services API may return the following errors:

  • 400 — Bad request
  • 401 — Unauthorized
  • 404 — Not found
  • 413 — Content too large
  • 422 — Unprocessable entity
  • 500 — Internal server error

Throttling

  • API calls per connection: 100 per 60 seconds.

Platform Limits

File Size

  • Maximum: 25 MB per request
    Applies to both single‑file and multi‑file operations.

    Total combined pages across multiple documents may exceed 250.

Retention Time

  • Input and output files are deleted ~15 minutes after operation completion.

Notes

  • Extraction connectors always return JSON.
  • Conversions and Transformations can output JSON or binary depending on the Accept header.
