Features and specs

What each product offers, as listed by its team.

Converterer 8 features
php eventloop 5 features
  • 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.
  • Simple and lightweight
    The library provides a minimalistic implementation of an event loop in PHP, making it easy to understand and integrate into small projects without heavy dependencies.
  • Educational value
    As a straightforward PHP event loop implementation, it serves as a great learning resource for developers wanting to understand how event loops and asynchronous programming concepts work under the hood in PHP.
  • Non-blocking I/O support
    The library enables non-blocking I/O operations in PHP, allowing developers to handle multiple tasks concurrently without relying on multi-threading, which PHP does not natively support well.
  • Timer and periodic task support
    It provides built-in support for timers and periodic tasks, enabling developers to schedule recurring operations or delayed execution within the event loop.
  • Pure PHP implementation
    The library is written in pure PHP without requiring external C extensions, making it portable and easy to install across different PHP environments without special compilation steps.

Possible disadvantages

  • Limited community and support
    The project has a very small community with minimal stars, forks, and contributors on GitHub, which means limited peer support, fewer bug reports, and potentially slower issue resolution.
  • Not production-ready
    Given its small scale and limited adoption, the library may not be battle-tested enough for production environments where reliability, performance, and stability are critical.
  • Limited features compared to alternatives
    More established PHP async libraries like ReactPHP, AmpPHP, and others offer far more comprehensive ecosystems with HTTP servers, database clients, and stream handling that this library lacks.
  • Performance limitations
    Being a pure PHP implementation without leveraging extensions like ev, libuv, or swoole, the event loop may suffer from performance bottlenecks compared to extension-backed alternatives when handling high concurrency.
  • Poor documentation
    The repository has minimal documentation and examples, making it difficult for new users to understand the full API, edge cases, and best practices for using the library effectively.

Questions & Answers

As answered by people managing Converterer and php eventloop.

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).
