Api2Pdf alternative

Looking for an alternative to Api2Pdf?

Api2Pdf is the budget option in PDF generation: pure usage billing across three selectable engines. Converterer trades that for flat monthly pricing, signed webhooks, delivery into your own storage, and a much wider conversion surface on the same plan.

Pricing

What the same volume costs.

An honest comparison: for small documents at modest volume, Api2Pdf will usually cost less in raw dollars. What you are buying with a flat plan is a bill that does not move when document sizes do, plus everything else on this page.

Monthly volume	Converterer	Api2Pdf
2,500 / month	$9.99 (Starter)	Usage-based: often under $10 for small documents, more for heavy ones
10,000 / month	$29.99 (Growth)	Usage-based: scales with megabytes generated and compute seconds

Api2Pdf published rates as of July 2026: $1/month base, $0.001 per MB of bandwidth, ~$0.0002 per compute second; actual totals depend entirely on document size and render time. Converterer overage: $0.003–0.03 per extra conversion depending on plan (Volume tier: $249.99/month for 250,000).

What Converterer brings

Features worth comparing.

Predictable billing

A flat plan you can put in a budget. Usage-based pricing is cheap until a template change doubles your document sizes.

One plan, two APIs

Website capture (URL to print-ready PDF) and 300+ file-conversion pairs under the same account and allowance.

Real browser fidelity

Web fonts, SVG, Flexbox, Grid, and JavaScript-heavy pages render exactly as Chrome shows them.

Recurring free tier

100 conversions every month, no card, not a one-time trial.

Webhook callbacks

HMAC-signed notifications the moment a render finishes, no polling.

Storage flexibility

Built-in storage by default, or deliver straight to your own S3, B2, GCS, or Azure bucket. Results are not parked on a shared host.

Office conversions included

DOCX to PDF, XLSX to PDF, PPT to PDF, and hundreds of other pairs on the same allowance.

Running since 2018

The capture engine powered Paperplane, a paid HTML-to-PDF service, for eight years before the rebrand.

Migration

Moving a PDF workflow across.

If your documents are already web pages (invoice views, report dashboards, proposal templates), rendering them on Converterer is one request: send the URL, get a job id, and the PDF lands in storage with a signed webhook on completion. Office documents convert through the file-conversion API on the same key.

# Render a URL to PDF, get a job ID back instantly.
curl -u "$CONVERTERER_API_KEY:" \
  https://api.converterer.com/jobs \
  -d url="https://yourapp.com/invoices/1042" \
  -d page_size=A4
# → {"id":"9f1a8e7c-…", "status":"queued"} - result lands in your storage

Honest take

When Api2Pdf is the better fit.

Your volume is low or spiky and your documents are small: Api2Pdf's usage pricing is genuinely hard to beat on raw cost.
You need wkhtmltopdf compatibility for legacy templates, or LibreOffice as a selectable engine.
You generate very large documents: Api2Pdf advertises GB-sized PDF support.
You need PDF merging as a first-class API operation.
