Features and specs

What each product offers, as listed by its team.

Api2Pdf 5 features
Converterer 8 features
  • Ease of Use
    Api2Pdf provides a straightforward API that allows developers to easily integrate PDF creation capabilities into their applications without extensive setup or configuration.
  • Multiple Formats
    The service supports converting a variety of formats to PDF including HTML, URLs, and Word documents, offering flexibility for different needs.
  • No File Storage
    Api2Pdf does not store files on their servers, which enhances privacy and compliance with data protection regulations.
  • High Quality Rendering
    Leveraging the wkhtmltopdf and Headless Chrome engines, Api2Pdf provides high-quality rendering of PDFs, which is vital for professional documentation.
  • Scalable Solution
    Api2Pdf can handle a large number of PDF conversions, making it suitable for businesses that require scaling.

Possible disadvantages

  • Cost
    The service can become expensive as usage increases, especially for businesses with high-volume needs.
  • Limited Customization
    Customization options may be limited when compared to other solutions that provide extensive control over the PDF output.
  • Dependency on Third-party
    Relying on an external API service introduces dependency, which can be a risk if the service experiences downtime or changes its terms.
  • Latency
    There can be latency issues due to network conditions or the processing time for large or complex files, affecting real-time applications.
  • Limited Offline Capability
    Since it's a web-based service, users need an internet connection to use it, which might not be suitable for offline applications.
  • 300+ Conversion Pairs
    Convert documents, spreadsheets, presentations, images, audio, and video through one REST endpoint: DOCX to PDF, HEIC to JPG, MP4 to GIF, XLSX to CSV, and hundreds more.
  • 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.
  • Batch and Parallel Processing
    Submit multiple jobs at once and keep high-volume workflows moving; async job handling with completion callbacks is built in.

Questions & Answers

As answered by people managing Api2Pdf and Converterer.

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).
