Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

n8n-nodes-pdfops

n8n community node for the PDFops API — deterministic PDF operations for workflows: inspect and fill AcroForm fields, merge PDFs, and generate invoice PDFs from structured data. No headless browser, no native dependencies; PDF processing runs on the hosted API.

Works keyless out of the box (100 requests/IP/month). A free API key (250 requests/month, no card) raises the quota and unlocks usage introspection — get one in 60 seconds at pdfops.dev/docs/signup#n8n, which also has a credentialed example workflow.

Installation

This community node is verified by n8n (listed in n8n's verified community-node registry since 2026-08-13).

Self-hosted — Settings → Community Nodes → Install → n8n-nodes-pdfops, or from the CLI:

n8n community-node install n8n-nodes-pdfops

Operations

| Operation | What it does | | --- | --- | | Inspect Fields | Lists a PDF's AcroForm fields — names, types, options, current values — plus a paste-ready fill template. Use it first on unfamiliar PDFs. | | Fill Form | Fills AcroForm fields in a PDF (from a binary field) and outputs the filled PDF as binary data. Optionally Flatten the result to lock the values into the page (fields become non-interactive). | | Merge | Merges the PDFs from all incoming items (in item order) into a single output PDF. | | Generate Invoice | Turns structured JSON (from, to, items, tax, currency…) into a complete US-Letter invoice PDF — no template needed. | | Get Usage | Returns tier, quota, used, remaining, and reset date for your API key. |

Fill, merge, and invoice are deterministic: the same input produces a byte-identical PDF, so re-running a workflow never produces spurious diffs.

Credentials

Create a PDFops API credential with your API key (sent as X-API-Key). The credential is optional for every operation except Get Usage — without it, requests count against the anonymous per-IP quota.

Example: invoice on every Stripe payment

  1. Stripe Trigger (payment_intent.succeeded)
  2. PDFops — Generate Invoice, mapping customer + line items into the invoice JSON
  3. Write Binary File / email / upload the resulting PDF
