Converterer (formerly Paperplane) is a REST API for file conversion and website capture, built for developers and no-code workflows.

File conversion: convert documents, spreadsheets, presentations, images, audio, and video across 300+ format pairs: DOCX to PDF, PDF to DOCX, XLSX to CSV, PNG to WebP, HEIC to JPG, MP4 to GIF, WAV to MP3, and hundreds more. Upload a file or pass a URL, and the converted file is delivered to built-in storage or your own bucket.

Website capture: render any URL as a pixel-perfect, print-ready PDF with a real headless Chromium engine, the same rendering path that has powered Paperplane since 2018. Page size, margins, headers and footers with page numbers, HTTP auth, and wait conditions for JavaScript-heavy pages are all parameters on a single call.

Built for developers: plain REST with curl-friendly endpoints, no SDK needed, just POST it. Code recipes for Python, Node.js, PHP, Laravel, Ruby, Go, Java, and plain cURL. Async jobs with signed (HMAC) webhooks, metadata passthrough, custom file names, and a synchronous capture endpoint when you want the PDF back in one request.

No-code and automation: drop conversion and capture into Zapier, Make, n8n, Power Automate, or Workato flows.

Storage your way: results land in the built-in destination with zero setup, or connect your own bucket (S3-compatible, Google Cloud Storage, Azure, and more).

Pricing: 100 free conversions a month, no credit card required, files up to 1 GB on every plan. Paid plans from $9.99/month including 2,500 conversions.

Formerly Paperplane (est. 2018): same team and infrastructure, expanded from HTML-to-PDF to full file conversion.

Adonis JS features and specs

  • Modern Eco-System
    AdonisJS uses the latest JavaScript (ES6/ES7) features, providing an up-to-date and efficient development environment. This includes async/await for handling asynchronous code, making it easier to write and understand.
  • ORM Support
    The framework includes a built-in ORM called Lucid, which simplifies database interactions by allowing developers to work with database records through straightforward JavaScript models.
  • MVC Architecture
    AdonisJS follows the Model-View-Controller (MVC) design pattern, which helps organize code in a clean and maintainable manner, making it easier to manage large applications.
  • Built-In Authentication and Authorization
    AdonisJS comes with out-of-the-box solutions for user authentication and authorization, reducing the time required to set up these critical features in applications.
  • Thorough Documentation
    AdonisJS provides comprehensive and well-maintained documentation, which makes it easier for developers to get started and find solutions to their problems quickly.
  • Rich CLI
    The Command Line Interface (CLI) for AdonisJS is rich with features, facilitating a range of tasks from project scaffolding to running migrations, thus speeding up the development process.

Possible disadvantages of Adonis JS

  • Learning Curve
    Although the framework is well-documented, its rich set of features and unique conventions can present a steep learning curve for beginners or those new to JavaScript frameworks.
  • Limited Ecosystem
    Compared to more established frameworks like Express.js or Laravel, AdonisJS has a smaller ecosystem of third-party packages and community resources.
  • Performance Overhead
    Due to its comprehensive feature set, AdonisJS can have more performance overhead compared to microframeworks that offer more control and fewer built-in features.
  • Smaller Community
    While growing, the community around AdonisJS is still smaller than that of other established frameworks. This can sometimes make it more challenging to find community-driven support and solutions.
  • Rapid Changes
    As a relatively new framework, AdonisJS undergoes frequent updates and changes. Keeping up with these changes can demand additional effort from developers.

Converterer features and specs

  • 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.

It is especially beneficial for those who appreciate a well-documented toolkit with out-of-the-box features necessary for web development.

Questions & Answers

As answered by people managing Adonis JS 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).

  • I Built a SaaS with AdonisJS 7, and I Loved It
    If you've never seen Adonis in the wild, or you've only ever reached for Next.js / Nuxt / a decoupled SPA, this article is the gentle tour I wish I'd had. - Source: dev.to / about 2 months ago
  • You're Doing Rails Wrong
    Batteries included backend frameworks exists in the JS ecosystem, just look at https://adonisjs.com/ . The problem is that the nodejs ecosystem started off with micro-frameworks as the antithesis to what they believed were โ€œoverbearingโ€ frameworks, like rails and Django, at the time. I remember expressโ€™s selling point was to build quick and dirty. - Source: Hacker News / 10 months ago
  • The One-Person Framework in Practice
    I'm currently building out an app using AdonisJS. Its billed as a Rails like experience but in node. https://adonisjs.com/ I did a comparison between Rails, Adonis and Fiber (a Go "framework") before settling on Adonis (mostly due to node ecosystem and type safety). It's been excellent so far, and the creator has an excellent series of tutorial videos that can get you up to speed quickly... - Source: Hacker News / over 1 year ago

    Database Migration files and Models: For my backend, my go to NodeJs framework is AdonisJS.
