Generate, process, and sign documents with a single API.

PDFops.dev logo PDFops.dev

A hosted PDF API for edge runtimes โ€” fill AcroForm fields and merge PDFs from a single HTTP call. Deterministic output, no headless browser, callable from Vercel/Cloudflare edge functions.

PDFGate is a developer-first platform for generating PDFs, sending documents for signature, and managing document workflows. Convert HTML to PDFs, create fillable documents, and automate processing tasks like data extraction, watermarking, and encryption โ€” all through a simple and scalable API.

PDFops is a hosted PDF API built for edge runtimes (Cloudflare Workers, Vercel Edge, Deno, Bun). Two endpoints, one HTTP call each:

  • Fill AcroForm fields in an existing PDF from a JSON map of field โ†’ value.
  • Merge multiple PDFs into one.

What's different from cloud PDF platforms: no headless browser, no native binaries, and deterministic, byte-identical output for the same input โ€” so you can hash, cache, diff, and sign the result. It's callable directly from an edge function: POST a template plus data, get bytes back.

Built for developers and AI apps that need to write PDFs programmatically without operating a rendering service. Free tier: 100 requests/month per IP, no signup. Pro: $16 for 4,000 calls ($0.004/call) โ€” about 25ร— cheaper per call than incumbent hosted APIs.

Also free, no signup: a PDF field Inspector (paste a PDF, see its AcroForm fields) and a live playground.

PDFGate features and specs

  • Accessibility
    PDFGate allows users to access and convert PDF documents from anywhere with an internet connection, making it convenient for remote work and collaborations.
  • User-Friendly Interface
    The platform is designed with an intuitive interface, making it easy for users of all technical levels to navigate and use the service effectively.
  • Multiple Format Support
    PDFGate supports the conversion of PDF files to a variety of formats, offering flexibility in how users use and share their documents.

Possible disadvantages of PDFGate

  • Subscription Cost
    Access to some features of PDFGate might require a paid subscription, which could be a downside for users seeking a free service.
  • Internet Dependency
    The service requires an internet connection to access its functionalities, which can be a limitation in areas with unreliable internet.
  • Privacy Concerns
    Uploading documents to an online platform might raise privacy issues for sensitive documents, as users must trust the service with their data.

PDFops.dev features and specs

  • Developer-focused API
    PDFops.dev appears to be designed as an API-first PDF processing service, making it straightforward for developers to integrate PDF operations like merging, splitting, converting, and manipulation directly into their applications.
  • Automation of PDF tasks
    By offering programmatic access to common PDF operations, it enables automation of repetitive document workflows without manual intervention, saving time for teams handling large volumes of documents.
  • Cloud-based convenience
    As a hosted service, it likely removes the need to install, configure, and maintain complex PDF libraries or dependencies locally, reducing infrastructure overhead.
  • Broad range of operations
    Services of this type typically support a wide variety of PDF functions such as conversion, compression, watermarking, and text extraction, providing an all-in-one toolkit for document handling.
  • Scalability
    A cloud API can handle scaling document processing demands more easily than a self-hosted solution, which is beneficial for growing applications with fluctuating workloads.

Possible disadvantages of PDFops.dev

  • Dependency on third-party service
    Relying on an external API means your application's PDF functionality is tied to the availability, uptime, and continued operation of PDFops.dev, introducing a potential single point of failure.
  • Data privacy concerns
    Sending documents to a third-party cloud service may raise privacy and compliance issues, especially for sensitive or regulated data that shouldn't leave your own infrastructure.
  • Potential cost at scale
    Usage-based API pricing can become expensive as document processing volume grows, potentially making it less economical than a self-hosted open-source alternative for high-volume use.
  • Limited offline capability
    Because it is a cloud service, it requires an internet connection and cannot be used in air-gapped or offline environments where local processing would be necessary.
  • Uncertain maturity and support
    As a newer or niche developer service, it may have limited documentation, community support, and a shorter track record compared to well-established PDF libraries and platforms.

Questions & Answers

As answered by people managing PDFGate and PDFops.dev.

What's the story behind your product?

PDFops.dev's answer:

PDFops started from a recurring edge-runtime pain: nearly every PDF API assumes a server with a headless browser or native libraries, which you cannot run inside a V8 isolate like Cloudflare Workers or Vercel Edge. PDFops is the deterministic write-and-merge primitive built for that environment โ€” one HTTP call, predictable bytes out.

Which are the primary technologies used for building your product?

PDFops.dev's answer:

TypeScript on the Hono web framework, with a pure-JavaScript PDF engine (a maintained pdf-lib fork) and no native dependencies. That combination runs inside V8 isolates, which is what lets PDFops execute on edge runtimes such as Cloudflare Workers and Vercel Edge.

Why should a person choose your product over its competitors?

PDFops.dev's answer:

No per-call tax: $0.004 per call versus the ~$0.10 typical of incumbent hosted PDF APIs (~25ร— cheaper). It runs at the edge instead of round-tripping to a vendor cloud, the output is deterministic (hashable and cacheable), and there is a free, no-signup tier plus a PDF field Inspector for exploring a documentโ€™s AcroForm fields before writing any code.

What makes your product unique?

PDFops.dev's answer:

Deterministic, byte-identical PDF output from a single HTTP call โ€” and it runs from edge runtimes (Cloudflare Workers, Vercel Edge, Deno, Bun) with no headless browser and no native dependencies. The same input always yields the same bytes, so you can hash, cache, diff, and sign the result.

How would you describe the primary audience of your product?

PDFops.dev's answer:

Developers and AI-application builders who need to fill AcroForm fields or merge PDFs programmatically โ€” especially teams deploying on edge runtimes who cannot run a headless browser or native PDF binaries inside a V8 isolate.

    Hey there, Iโ€™m the founder of [PDFGate](https://pdfgate.com), an API that converts HTML into PDFs with support for fillable forms, encryption, and digital signatures. Like many here, Iโ€™ve run into the same frustration: most HTML to PDF tools are either missing core features or feel outdated.
