Converterer 8 features
HTML2PDF Rocket 4 features
  • 300+ Conversion Pairs

  • Website Capture (HTML to PDF)
    Render any URL as a pixel-perfect, print-ready PDF with a real headless Chromium engine. Page size, margins, headers and footers with page numbers, and wait conditions for JavaScript-heavy pages are all parameters on one call.
  • No SDK Required
    Plain REST that works from any language: authenticate with HTTP Basic, POST a file or URL, done. Hand-tested code recipes for Python, Node.js, PHP, Laravel, Ruby, Go, Java, and plain cURL.
  • Signed Webhook Callbacks
    HMAC-signed notifications fire the moment a conversion finishes, so pipelines react instantly instead of polling for status.
  • Bring Your Own Storage
    Results land in built-in storage with zero setup, or deliver straight to your own bucket: S3-compatible, Google Cloud Storage, Azure, and more.
  • No-Code Integrations
    Drop conversion and capture into Zapier, Make, n8n, Power Automate, or Workato workflows without writing code.
  • Flat Per-Conversion Pricing
    A conversion costs the same whatever the file weighs, with files up to 1 GB on every plan. 100 free conversions a month with no card, and published plans from $9.99 up to 250,000 conversions a month.

  • Dependence on Internet Connectivity
    As an online service, HTML2PDF Rocket requires a stable internet connection, which can be a limitation for users in areas with unreliable connectivity.

Questions & Answers

As answered by people managing Converterer and HTML2PDF Rocket.

What makes your product unique?

Converterer's answer

Two APIs under one plan and one allowance: file conversion across 300+ format pairs (documents, spreadsheets, presentations, images, audio, video) and website capture that renders any URL as a print-ready PDF with a real headless Chromium engine. Pricing is flat per conversion, so a 900 MB video costs the same as a 40 KB document, where most competitors bill credits or processing minutes that scale with file size. And there is no SDK to install: it is plain REST you can drive from cURL.

Why should a person choose your product over its competitors?

Converterer's answer

Predictable cost and less integration work. Flat per-conversion pricing with files up to 1 GB on every plan means no surprise bills when documents get heavy. The free tier is a real recurring allowance, 100 conversions every month with no card, rather than a one-time trial. Integration is one POST request with HTTP Basic auth, HMAC-signed webhooks instead of polling, and delivery straight into your own storage bucket if you want it. The capture engine has been rendering PDFs in production since 2018, and we publish sourced, dated comparisons against competitors on our own site, including the cases where they are the better fit.

How would you describe the primary audience of your product?

Converterer's answer

Developers adding file conversion or document rendering to their products (invoices, reports, archives, media processing), and operations or no-code builders automating the same jobs through Zapier, Make, n8n, Power Automate, or Workato. Typical users are SaaS teams generating documents at scale and teams replacing self-hosted conversion stacks they no longer want to operate.

What's the story behind your product?

Converterer's answer

Converterer started in 2018 as Paperplane, a focused HTML-to-PDF API built on headless Chrome. Customers kept asking for conversions that had nothing to do with HTML: DOCX to PDF, HEIC to JPG, MP4 to GIF. So the platform grew past its name, and in May 2026 it relaunched as Converterer: the same team and rendering engine, expanded to a full file conversion API with 300+ format pairs alongside the original website capture.

Which are the primary technologies used for building your product?

Converterer's answer

Website capture runs on a real headless Chromium engine, so output matches what desktop Chrome renders, including web fonts, Flexbox, Grid, and JavaScript-heavy pages. The API itself is plain REST over HTTPS with HTTP Basic authentication and HMAC-signed webhooks, and output delivery integrates with standard object storage (S3-compatible, Google Cloud Storage, Azure).
