What Converterer brings

Features worth comparing.

A real free tier

100 conversions every month with no card. Urlbox offers a 7-day trial, then the cheapest plan is $19.

One plan, two APIs

Print-ready PDFs from URLs, plus 300+ file-conversion pairs, drawing from a single allowance.

S3 delivery on every plan

Your own S3, B2, GCS, or Azure bucket from the first dollar, not gated to a higher tier.

Real browser fidelity

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

PDF capture included

Print-clean PDFs with page size, margins, and header/footer control from the same endpoint.

Webhook callbacks

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

No-code workflows

Zapier, Make, n8n, and Power Automate paths for the same API.

Running since 2018

The capture engine powered Paperplane, a paid rendering service, for eight years before the rebrand.

Migration

Moving a capture workflow across.

Captures are one request: send the URL, get a job id, and the print-ready PDF lands in storage with a signed webhook on completion. Page size, margins, and header/footer templates ride on the same call, and file conversion shares the same key and allowance.

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

Honest take

When Urlbox is the better fit.

You need PNG or JPG image output today: Converterer's capture currently ships print-ready PDF only.
You need a contractual SLA: Urlbox publishes 99.95–99.99% uptime commitments by tier.
You serve render links directly to end users: their 30-day cache turns repeat views into a single render.
You need WebP output.
At exactly 15,000 renders/month their Ultra plan edges out Converterer's Scale on price ($99 vs $99.99), if you will never grow past it.
