Alternative to iLovePDF API

iLovePDF API vs TemplateFox

iLovePDF API is a broad PDF toolkit — merge, split, compress, OCR, convert, sign, and HTML-to-PDF in one service. TemplateFox is focused on template-based HTML-to-PDF generation. If you need the broader toolkit, iLovePDF is probably the right call. If your core use case is generating documents from templates with data binding — here's how we compare.

What is iLovePDF API?

iLovePDF API — marketed today as iLoveAPI — is the developer-facing product from the team behind iLovePDF.com, the well-known consumer PDF tools site. It packages the same toolkit that powers the consumer site into a REST API, with official SDKs in PHP, .NET, Ruby and Node.js.

It covers a wide surface: merge, split, extract, compress, OCR, convert Office and images, protect/unlock, watermark, rotate, repair, page numbering, PDF/A conversion and validation, digital signatures, and HTML-to-PDF. If you need “a PDF API” in the general sense — a Swiss-army backend for whatever arrives in your inbox — this is one of the broader offerings on the market.

The HTML-to-PDF tool is one slot in that toolkit rather than its focus. The public API reference notes that HTML-to-PDF has no extra parameters — you send HTML and get a PDF. There's no template storage, no visual editor, no variables-loops-conditions layer: that logic lives in your code. For teams whose main job is generating documents from structured data, that's where TemplateFox takes a different shape.

Pricing

iLovePDF API uses a credit-based model. New accounts get 2,500 free credits per month. Each tool has its own credit cost per file: HTML-to-PDF and most PDF operations run ~10 credits per file, merge is 5, OCR is 5 per page, digital signatures 80 per envelope. Unused subscription credits expire monthly; prepaid packages don't expire. Annual subscriptions are 20% off. Concrete dollar tiers aren't listed as a fixed table — the site surfaces prices through a pricing calculator based on which tools you plan to call. Fair model if you're spread across many tools; noisier to reason about if your only job is generating 1,000 HTML PDFs a month.

Feature comparison

Honest side-by-side. We don't overlap on most of what iLovePDF does — that matters more than any individual cell.

1. Product scope

Feature
iLovePDF API
TemplateFox
HTML-to-PDF generation
Yes (thin wrapper, no extra parameters)
Core product (templates + data binding)
Merge / split / extract pages
Yes (core strength)
Not supported
Compress PDF
Yes
Not supported
OCR (scanned PDFs → text)
Yes
Not supported
Office / image conversion
Yes (Word, PowerPoint, Excel, images)
Not supported
Digital signatures, watermarks, repair
Yes
Not supported

iLovePDF wins breadth, clearly and honestly. Merge, split, compress, OCR, Office conversion, digital signatures — TemplateFox does none of that. If your workload mixes those operations, iLovePDF is the right pick. TemplateFox is narrower and deeper on one axis only: template-based HTML-to-PDF with stored templates and data binding.

2. HTML-to-PDF rendering

Feature
iLovePDF API
TemplateFox
Modern CSS rendering
Supported
Flexbox, Grid, modern CSS
PDF/A output
Yes (separate PDF/A tool)
PDF/A-1b, A-2b, A-3b
PDF/UA accessibility
Not documented
Supported
Headers, footers, page numbers
Via separate page-numbers tool
Native in template editor

On the dimension where we actually overlap, iLovePDF's HTML-to-PDF is documented as a thin wrapper — no extra parameters, no template-level options. It does support PDF/A via a separate conversion step. TemplateFox exposes PDF/A, PDF/X and PDF/UA directly on the generation call, plus native headers, footers and page-number controls inside the template.

3. Templates & developer experience

Feature
iLovePDF API
TemplateFox
Visual template editor
None (send raw HTML per request)
Drag-and-drop editor
Stored, reusable templates
None (no template storage)
Templates with versioning
Variables, loops, conditions
Manual (bring your own templating)
Built-in
Built-in barcodes & QR
Not available
Code128, EAN-13, QR…
SDK languages
PHP, .NET, Ruby, Node.js (4)
7 languages
No-code integrations
None (official)
Zapier, Make, n8n, Airtable, Bubble

This is the clearest product-shape difference. iLovePDF sends raw HTML per request with no concept of a stored, reusable template. TemplateFox is template-first: design once in the visual editor, call the API with JSON data, and the layout, barcodes, variables and loops are already wired. If your documents are generated repeatedly from structured data, that saves the templating and HTML-stitching work entirely.

4. Pricing & commercial terms

Feature
iLovePDF API
TemplateFox
Free tier
2,500 credits/mo (~250 HTML PDFs)
60 PDFs/mo
Pricing model
Credit-based (cost varies per tool)
Flat per-PDF subscription
Starter plan
Credit packages / calculator-based
$19/mo flat
Credit expiry
Monthly credits expire at month end
Monthly quota (same)
Annual discount
20% off yearly
25% off yearly (3 months free)

Both have a meaningful free tier. iLovePDF's credit model fits teams spreading across many tools; it becomes harder to predict when your only job is one operation. TemplateFox's flat per-PDF subscription (Starter at $19/mo for 1,000 PDFs) maps cleanly to template-based generation workloads. At 1,000 HTML-to-PDF/month TemplateFox is usually the cheaper and simpler answer; at mixed-tool volume iLovePDF's shared credit pool may win.

Generating documents from templates, not manipulating arbitrary PDFs?

TemplateFox is built for that specific job — visual editor, stored templates, data binding. No credit card, 60 free PDFs per month.

When each tool is the right call

Two honest answers, depending on the shape of your workload.

Pick TemplateFox

When template-based generation is the job

  • You generate invoices, receipts, contracts, certificates or reports repeatedly from structured data
  • You want a visual template editor, not HTML string interpolation in your backend
  • Variables, loops, conditions and built-in barcodes should be template primitives, not extra libraries
  • Non-technical teammates need to edit templates without touching code or redeploying
  • You want to plug PDF generation into Zapier, Make, n8n, Airtable or Bubble
  • Flat per-PDF pricing is easier to model than credit-by-tool math

When you need the broader PDF toolkit

  • Your workload is PDF manipulation — merging batches, splitting long scans, extracting pages
  • You need OCR on legacy scanned documents, or compression for email attachments
  • You convert Office files (Word, Excel, PowerPoint) or images to PDF as part of the flow
  • Digital signatures, watermarks, protect/unlock are part of the product
  • You already have an iLovePDF account and integration in place and don't want to migrate

iLovePDF's breadth is a real strength. For a mixed PDF-manipulation workload behind one account and one credit pool, it's a strong pick — and genuinely not something we compete with.

Frequently asked questions

How does iLovePDF API pricing work?

iLovePDF uses a credit-based model. Every new account gets 2,500 free credits per month. Each tool costs a different number of credits per file: HTML-to-PDF and most PDF operations run around 10 credits per file, merge is 5, OCR is 5 per page, digital signatures 80 per envelope. Unused subscription credits expire at the end of the month. Prepaid credit packages don't expire. There's a 20% discount on annual plans. Specific dollar amounts are surfaced through their pricing calculator rather than listed tiers.

What is iLovePDF API best at?

Breadth. If your use case is PDF manipulation — merging a batch of supplier invoices, splitting a 500-page scan, OCR'ing legacy documents, compressing PDFs for email, converting Word/Excel to PDF, or handling digital signatures — iLovePDF is a strong fit. One API, one account, one set of credits for a very wide toolkit. That breadth is genuinely hard to match.

How does TemplateFox compare?

TemplateFox is focused on a single thing: generating PDFs from templates. You design a template in a visual editor, add variables, loops and conditions, then call the API with JSON data — the PDF comes back. iLovePDF's HTML-to-PDF endpoint, by contrast, takes raw HTML per request with no template storage and no extra parameters. For invoices, receipts, contracts, certificates and reports that get generated repeatedly from structured data, TemplateFox is the more direct tool. For merging, splitting, compressing or OCR'ing arbitrary PDFs, it's the wrong tool — we don't do those.

Can I migrate my iLovePDF HTML-to-PDF calls to TemplateFox?

Yes, and usually it's a simplification. If you're currently generating HTML server-side, interpolating variables into a string, and POSTing it to iLovePDF per request, that logic moves into a TemplateFox template once. Subsequent calls send JSON data only — the template handles layout, variables, loops and barcodes. Most HTML migrations take under an hour per template.

Do both support PDF/A?

Yes. iLovePDF has a dedicated PDF/A conversion tool and a PDF/A validator. TemplateFox supports PDF/A-1b, A-2b, A-3b, PDF/X and PDF/UA as output formats on the generation call — you pass the desired standard as a parameter and the PDF comes out compliant. Different shape (post-hoc conversion vs. compliant-by-generation), same outcome for most archival needs.

Which is cheaper at 1,000 HTML-to-PDF per month?

At roughly 10 credits per HTML-to-PDF file, 1,000 documents uses ~10,000 credits — well beyond the 2,500 free tier, and into a paid iLovePDF plan or prepaid package. TemplateFox's Starter plan is $19/month flat for 1,000 PDFs, no credits-by-tool math. At that volume TemplateFox is usually simpler and cheaper. If your volume spikes across many tools (merge + compress + OCR + HTML), iLovePDF's shared credit pool may still come out ahead.

Which should I pick?

Pick iLovePDF if you need the broader PDF toolkit in a single API: merge, split, compress, OCR, Office conversion, digital signatures. Pick TemplateFox if your core use case is template-based document generation — invoices, reports, contracts, certificates — and you want a visual editor, stored templates, data binding, barcodes and no-code integrations. They overlap only on the HTML-to-PDF slice.

How much does TemplateFox cost?

There's a free tier with 60 PDFs per month, no credit card required. Paid plans start at $19/month for 1,000 PDFs, flat pricing — no credit multipliers per tool. Annual plans are 25% off (3 months free). See pricing.
