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.

Nextcloud Forms features and specs

  • Open Source
    Nextcloud Forms is open-source software, which means it is free to use and can be modified to fit specific needs. This allows organizations to have full control over their data and customize the tool as required.
  • Integration with Nextcloud
    Being a part of the Nextcloud ecosystem, it integrates seamlessly with other Nextcloud apps such as Files, Calendar, and Contacts. This creates a cohesive experience for users already utilizing Nextcloud services.
  • Data Privacy
    Nextcloud Forms allows users to host the application on their own server, providing enhanced control over data privacy and security. This is particularly important for organizations that handle sensitive information.
  • User-Friendly Interface
    The forms creator and interface are designed to be intuitive, making it easy for users to create and manage forms without requiring extensive technical knowledge.
  • Customizable
    Users have the ability to customize forms with various question types, themes, and configurations to suit their individual needs and preferences.

Possible disadvantages of Nextcloud Forms

  • Limited Features
    Compared to other form builders like Google Forms or Typeform, Nextcloud Forms can be lacking in some advanced features and integrations.
  • Self-Hosting Requirements
    Hosting Nextcloud Forms on a private server requires technical expertise and resources to set up and maintain the server, which may not be feasible for all users or small organizations.
  • Performance
    The performance and speed of the application can be highly dependent on the server's specifications and internet connection, which might not match the robustness of cloud-based solutions.
  • Community Support
    While there is community support, it might not be as immediate or extensive as the support provided by commercial form solutions, potentially leading to longer resolution times for issues.
  • Learning Curve
    For users unfamiliar with self-hosted applications or the Nextcloud environment, there might be a steeper learning curve in setting up and effectively using Nextcloud Forms.

Questions & Answers

As answered by people managing Converterer and Nextcloud Forms.

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).
