Features and specs

What each product offers, as listed by its team.

Foam 6 features

Converterer 8 features

Open Source
Foam is an open-source tool, which means it is free to use and allows for community-driven development and contributions. Users can modify the source code to fit their specific needs.
Markdown Support
Foam uses Markdown, a lightweight and easy-to-read syntax, making it simple to create and manage notes. This also allows for easy integration with other Markdown-based tools and platforms.
Integration with Visual Studio Code
Foam is designed to work seamlessly with Visual Studio Code (VS Code). This provides users with a powerful and familiar text editor environment, complete with extensions and customization options.
Graph View
Foam includes a graph visualization feature that helps users see and navigate the relationships between their notes, making it easier to understand and manage complex information.
Bidirectional Links
Foam supports bidirectional links, allowing users to create connections between notes in both directions. This enhances the note-taking experience by enabling a more interconnected and dynamic information structure.
Community and Documentation
Foam has a growing community of users and contributors, as well as comprehensive documentation. This support network helps users troubleshoot issues, share tips, and improve their knowledge of the tool.

Possible disadvantages

Limited to VS Code
Foam relies on Visual Studio Code as its primary environment. Users who prefer different text editors or platforms might find this limitation restrictive and less convenient.
Learning Curve
Although Foam leverages Markdown, users may still face a learning curve, especially if they are not familiar with VS Code or the specific features and extensions required to maximize Foam's capabilities.
Performance with Large Datasets
Foam can struggle with performance issues when handling large datasets or a high number of notes. This can lead to slow response times and inefficient workflows.
Limited Mobile Support
Foam is primarily designed for desktop use within VS Code, which means that mobile support is limited. Users looking for a seamless cross-platform experience might find this aspect lacking.
Customization Complexity
While Foam offers a high degree of customization, setting up and configuring the tool to meet personal preferences and workflows can be complex and time-consuming for some users.

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 Foam 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).
