Overview

What the PDF API Hub Zapier integration actually does

It links your PDF API Hub account to Zapier so that documents get produced and reworked without you opening a single file. PDF API Hub only works as an action here: a step in another app's automation that turns a web page, some HTML, a picture or an existing PDF into the document you want.

Three jobs come up again and again. First, the archive copy: Convert URL to PDF snapshots a web page, so a quote page or a published report ends up as a file you can store. Second, the readable scan: Extract PDF Text (OCR) pulls the words out of scanned pages, so a supplier invoice that was only a picture becomes text the next step can use. Third, the protected handout: Lock PDF puts a password on a document before it leaves your hands, and Add Watermark stamps it with your own text.

Now the part the app page skips. PDF API Hub has no trigger at all, so nothing that happens inside it can start a Zap; the starting event always comes from another tool. It has no search step either, so a Zap cannot look up an earlier document there. And every action works on what you hand it (a link, some HTML, a password), which means the step before has to carry that value.

The same app also has a page on the Make side: PDF API Hub Make integration. For the wider picture, see Make vs Zapier.

Vocabulary

Zapier words in one minute

Eight terms come back all over this page. Here they are in plain English, once.

Zap
The automation you build on Zapier: one starting event, then one or more steps that run each time that event happens.
Trigger
The event in an app that starts the Zap. Once the Zap is on, Zapier waits for it. PDF API Hub has none.
Action
What the Zap does after it starts: the step that creates, converts or sends something on your behalf.
Task
The unit Zapier bills: one action your Zap completes successfully. The allowance on your plan counts these.
Polling vs instant
A polling trigger is checked on a timer by Zapier. An instant trigger is reported by the app itself, so nothing waits for a check.
Filter
A step that lets the Zap carry on only when the incoming item meets your condition, and stops it otherwise.
Connection
Your PDF API Hub account linked to Zapier once, then reused by every step that calls PDF API Hub.
Multi-step Zap
Any Zap beyond one trigger and one action. A second action or a filter makes one, and it then needs a paid plan.
Cost

What a PDF API Hub Zap really costs

PDF API Hub is not reserved to paid plans, so it runs on the free Zapier plan. The bill depends on how many of its actions finish.

  • Free plan100 tasks a month, unlimited Zaps
  • Free plan shape2 steps: one trigger, one action
  • PDF API Hub accessEvery plan, free included
  • What is billedEach action that succeeds

The trigger from the other app costs nothing, and neither do Zapier's checks for new items. Each PDF API Hub action that succeeds counts as one task; a failed one is not counted. Chain Compress PDF and Lock PDF and every run eats two tasks. That chain is also a multi-step Zap, as is any Zap with a filter, so it needs a paid plan, whatever the app: the free plan stops at one trigger plus one action.

Connect

Connect PDF API Hub to Zapier in 3 steps

  1. 01

    Open your connections

    In your Zapier account, go to the Apps page and click + Add connection. You need an existing PDF API Hub account, plus access to anything you do not own yourself but want the Zap to touch.

  2. 02

    Pick PDF API Hub

    Type PDF API Hub in the search box of the dialog, select it, then click Add connection. A new tab opens on the PDF API Hub side for the last part of the setup.

  3. 03

    Sign in and grant access

    Log in to PDF API Hub in that tab and allow Zapier to use the account. From then on every PDF API Hub step in any Zap reuses this one connection, so you set it up once.

First Zap

Your first Zap: compress then lock new files

GoalEach new file in a Drive folder comes out smaller and password-protected.

  1. 01

    Pick the starting event

    Since PDF API Hub cannot start a Zap, the trigger comes from Google Drive: choose the event that watches the folder where your PDFs arrive.

  2. 02

    Test the trigger

    Run the test. Zapier brings back the three most recent items of the connected account, so you map the next steps on a real file rather than on a guess.

  3. 03

    Add Compress PDF

    Add a PDF API Hub step, pick Compress PDF, choose your connection and map the file link coming from the trigger into it.

  4. 04

    Add Lock PDF

    Add a second action, Lock PDF, feed it the compressed result and fill the Lock Passphrase. Two actions make this a multi-step Zap on a paid plan.

  5. 05

    Test, then publish

    Test each step once and read what came back before moving on. When both look right, publish the Zap to switch it on; each run then costs two tasks.

Actions

The 20 PDF API Hub actions

PDF API Hub gives you 20 actions. For each one: what it does for you, when to reach for it, and what to watch out for.

1

Compress PDF

Action

In Zapier“Compress a PDF URL to reduce file size.”

Give it the link of a heavy PDF and it returns a lighter version of the same document.

When to use it
files that bounce off email size limits or eat storage, such as photo-rich inspection reports.
Watch out
it reads the file from a link, so the trigger app has to hand one over.
2

Convert URL to HTML

Action

In Zapier“Fetch rendered HTML content from a URL.”

Rather than a file, this action brings back the rendered HTML of a page, the code the browser ends up showing.

When to use it
you want the content of a page as material for a later step, for instance to rebuild it as a PDF with your own styling.
Watch out
the URL field is required and nothing gets saved as a document on its own.
3

Convert HTML to Image

Action

In Zapier“Generate an image from HTML and CSS.”

This one renders your HTML and CSS as a picture instead of a document, handy when the result goes into a chat message or a social post rather than a folder.

When to use it
producing a visual card, such as a certificate preview, from data your Zap already holds.
Watch out
HTML Content is required here too.
4

Convert HTML to PDF

Action

In Zapier“Generate a PDF from HTML and CSS.”

Hand it a block of HTML and CSS and it builds a PDF from that markup, which is how a templated quote or receipt becomes a proper document.

When to use it
your form tool or CRM already holds the layout and you want a file to attach to an email.
Watch out
HTML Content is required, so an earlier step has to produce the markup.
5

Extract Image Text (OCR)

Action

In Zapier“Extract text from an image.”

Photos and screenshots go through the same character reading, without converting them to PDF first.

When to use it
business cards snapped at an event, whose details you want in your contact list.
Watch out
the output is plain text; splitting it into name or email needs another step.
6

Convert JPG to PDF

Action

In Zapier“Convert JPG image URLs to a PDF.”

Feed it links to JPG pictures and it bundles them into a single PDF, the usual fix for photos of receipts sent from a phone.

When to use it
an accountant who wants one document per expense claim instead of a pile of images.
Watch out
it expects image links, so the trigger app must expose where the pictures live.
7

Lock PDF

Action

In Zapier“Protect a PDF with a password.”

Puts a password on a PDF, so only people who know it can open the file.

When to use it
payslips or medical forms that HR sends out and that should not be readable if forwarded by mistake.
Watch out
the Lock Passphrase field is required; store that password somewhere the recipient can get it.
8

Merge PDFs

Action

In Zapier“Merge multiple PDF URLs into one PDF.”

Several PDF links in, one combined document out.

When to use it
joining a signed contract, its appendix and the invoice into one file for the client folder.
Watch out
every part must already be reachable by a link, so collect them in earlier steps first.
9

Parse PDF

Action

In Zapier“Extract text or structured data from a PDF URL.”

Reads a PDF from its link and returns the text, or structured data, that later steps can map into fields.

When to use it
order forms generated as PDFs whose content should end up as rows in a spreadsheet.
Watch out
a scanned page is a picture, not text; use the OCR version for those.
10

Extract PDF Text (OCR)

Action

In Zapier“Extract text from scanned PDF pages.”

OCR (reading characters off a picture) is what this action does on scanned PDF pages, turning images of paper into words.

When to use it
paper invoices scanned at the front desk that need their text in your accounting tool.
Watch out
on a PDF that already holds real text, Parse PDF is the simpler route.
11

Convert PDF to JPG

Action

In Zapier“Convert PDF pages to JPG images.”

Going the other way, this splits a PDF into its pages and turns each one into a JPG picture.

When to use it
showing the first page of a brochure as a preview in a newsletter or a team chat.
Watch out
one PDF gives several images, so plan what the next step does with more than one result.
12

Convert PDF to PNG

Action

In Zapier“Convert PDF pages to PNG images.”

Same split as the JPG version, but each page of the PDF comes back as a PNG image instead.

When to use it
a design team that needs each page of a spec as a clean image for a review tool.
Watch out
plan what the next step does with several images, one per page.
13

Convert PDF to WebP

Action

In Zapier“Convert PDF pages to WebP images.”

Pick this when the pages of a PDF are headed for a website: it outputs WebP images, the format many websites serve.

When to use it
publishing the pages of a monthly report as images in your content system.
Watch out
check that the destination accepts WebP before you build around it.
14

Convert PNG to PDF

Action

In Zapier“Convert PNG image URLs to a PDF.”

Same idea for PNG files: links to those images go in, a PDF comes out.

When to use it
screenshots or exported diagrams that a client wants as one document rather than separate attachments.
Watch out
mixing formats needs the matching action for each, since this step only takes PNG links.
15

Split PDF

Action

In Zapier“Split a PDF into pages, ranges, or chunks.”

The reverse of merging: one PDF goes in and comes out cut by pages, by ranges or by chunks.

When to use it
a batch of scanned delivery notes arriving as one file that you want to file note by note.
Watch out
Split Type is required, so decide how the cut is made before the test.
16

Unlock PDF

Action

In Zapier“Remove password protection from a PDF.”

Removes the password protection from a PDF so the next steps can read or rework it.

When to use it
bank statements that arrive locked and need text extraction before they reach your bookkeeping.
Watch out
without the right Unlock Passphrase, which is required, the step cannot open anything.
17

Convert URL to Image

Action

In Zapier“Capture a website URL as an image.”

A screenshot step: give it a site address and it captures the page as an image you can pass along.

When to use it
a marketing team keeping a visual record of a landing page every time a project tool marks it as live.
Watch out
Website URL is required, and Full Page is the option to look at for long pages.
18

Convert URL to PDF

Action

In Zapier“Capture a website URL as a PDF.”

Point this step at a web address and you get that page saved as a PDF, a frozen copy that will not change when the site does.

When to use it
keeping an archive of a published offer, an article or a status page for your records.
Watch out
Website URL is mandatory, and the Full Page option is where you choose to capture the page in full.
19

Add Watermark

Action

In Zapier“Add text watermark to a PDF or image.”

Stamps a line of text over a PDF or an image, like a “draft” or “confidential” label.

When to use it
marking proofs sent to a client for approval so nobody prints the unpaid version.
Watch out
Watermark Text is required, and the watermark is text, not a logo file.
20

Convert WebP to PDF

Action

In Zapier“Convert WebP image URLs to a PDF.”

WebP, the image format many websites now serve, gets turned into a PDF by this step from the image links you give it.

When to use it
product pictures pulled from an online shop that need to land in a printable catalogue page.
Watch out
like its JPG and PNG siblings, it works from links, not from attachments typed into the step.
When it breaks

When a PDF API Hub Zap breaks

Zapier attaches no help article to PDF API Hub, and no limit specific to the app is documented. What breaks comes from how Zaps behave in general.

One reassurance first: an action that does not go through is not billed. The four cases below are the ones to keep in mind. For a step-by-step method, there is Zapier troubleshooting.

  • Old files are never processed

    A Zap only reacts to what happens after you switch it on. The PDFs already sitting in your folder stay untouched, and moving that backlog is a separate job.

  • The Zap feeds itself

    Save the compressed or locked PDF back into the folder your trigger watches and the Zap starts again on its own output, burning tasks run after run.

  • A bulk upload gets held back

    Drop a large batch of files at once, after a migration for example, and Zapier's flood protection can pause the trigger instead of running every item.

  • The same file does not run twice

    On a polling trigger Zapier remembers what it has already seen, so re-saving a known item does not normally start the Zap a second time.

FAQ

PDF API Hub Zapier integration: questions people ask

01Is the PDF API Hub Zapier integration free?
Yes, as far as Zapier goes: PDF API Hub is not reserved to paid plans, so it works on the free plan. That plan gives you 100 tasks a month and unlimited Zaps, but each Zap is limited to two steps, one trigger and one action. A Zap that compresses a file and then locks it has two actions, so it needs a paid plan. Your PDF API Hub account itself is a separate matter, and this page has no information about its own pricing.
02How many tasks does a PDF API Hub Zap use?
One task per PDF API Hub action that succeeds, and nothing else. The trigger in the other app is free, and so are the checks Zapier runs to spot new items. If an action fails, it is not counted. In a Zap that merges, then compresses, then locks, a successful run costs three tasks, three times what a one-action Zap costs. With 100 tasks a month on the free plan, that difference shows up quickly.
03Does PDF API Hub work in real time with Zapier?
It depends entirely on the trigger, because PDF API Hub has none and only runs as an action. If the app that starts your Zap has an instant trigger, it reports the event itself and the run starts straight away, whatever your plan. If it uses a polling trigger, Zapier checks on a timer: every 15 minutes on Free, 2 on Professional, 1 on Team and Enterprise. Pick the starting app with that in mind.
04What does it take to connect PDF API Hub to Zapier?
A PDF API Hub account, and read or write access to anything you do not own yourself but want the Zap to touch. The connection is made from the Apps page of your Zapier account with + Add connection: you pick PDF API Hub, sign in to it in the tab that opens and grant Zapier access. After that, every PDF API Hub step in every Zap reuses the same connection.
05Can PDF API Hub unlock a PDF without the password?
No. The Unlock PDF action has a required Unlock Passphrase field, so the step needs the right password to remove the protection. The same goes the other way: Lock PDF requires a Lock Passphrase. In practice that means the password has to be known when you build the Zap, either typed as a fixed value or carried by an earlier step. A Zap cannot guess it, so settle where that password lives before you promise anyone automatic handling of protected statements.
06What if the PDF action you need is not in the list?
Then the Zap cannot do it through PDF API Hub, because the list of 20 actions is closed: no trigger, no search, nothing hidden behind a menu. Check the names in the editor first, since several actions overlap (Parse PDF reads PDFs that already hold text, Extract PDF Text (OCR) reads scans). If none fits, the job belongs to another app with its own Zapier actions, placed before or after the PDF API Hub step, which turns the Zap into a multi-step one.
07Zapier, Make or n8n for PDF API Hub?
Decide on criteria rather than on a ranking. On Zapier, PDF API Hub offers 20 actions and no trigger, works on the free plan, and each successful action costs one task. The free plan stops at two steps, so a chain such as convert, then lock, then watermark needs a paid plan. If your documents go through long chains every day, compare that task count with how the other tool bills a run. PDF API Hub also has a Make page to check against.
