EZdoc vs PDFShift AI generation vs. HTML-to-PDF conversion
PDFShift is a developer API that converts HTML you write into PDFs. EZdoc generates the document for you — from a description or a data merge — so there is no HTML to author, host, or maintain.
Skip writing the HTML you would have converted
PDFShift is a developer tool that converts HTML to PDF using a headless Chromium renderer. You send it a raw HTML string or a URL, it returns a PDF. It handles full CSS — custom fonts, flexbox, grid, JavaScript execution — and supports headers, footers, watermarks, password protection, and screenshot output (PNG/JPEG/WebP). It is intentionally minimal — there is no UI, no templates, and no AI. PDFShift is a rendering utility for developers who already own their document HTML and want reliable PDF output.
EZdoc starts one level higher. Describe the document you need and AI generates the content and layout in about 30 seconds — no HTML to write, no renderer to run, no template to maintain. For batch workflows, merge a CSV and EZdoc produces one personalized PDF per row natively. Developers get a REST API that returns finished documents rather than a rendering pipeline that expects finished HTML. If you would rather not author the HTML in the first place, EZdoc covers that ground.
EZdoc vs PDFShift — a plain-language comparison
PDFShift and EZdoc both produce PDFs, but they solve different problems and are built for different audiences. Understanding the distinction up front saves you from comparing features that don't map to each other.
What PDFShift does
PDFShift is a Chromium-based HTML-to-PDF conversion API. You send it a raw HTML string or a URL, it renders the page in a headless browser, and it returns a PDF. That's the entire product. It supports full modern CSS — flexbox, grid, custom fonts, JavaScript execution — plus headers, footers, watermarks, password protection, encryption, and screenshot output (PNG, JPEG, WebP). Parallel conversions (up to 50 at once) and async/webhook delivery are available on paid plans. REST API with official SDKs for Node.js, Python, PHP, Ruby, Go, and C#.
PDFShift has no AI features, no visual document editor, no template library, and no web UI for document creation. This is deliberate — PDFShift targets developers who already have HTML and need a reliable, high-fidelity PDF renderer. Its closest competitors are Gotenberg, WeasyPrint, Prince XML, and APITemplate.io — all developer rendering utilities.
What PDFShift does not do
PDFShift does not generate content. It does not write copy, draft layouts, or suggest structure. You bring the HTML; it brings the Chromium engine. If you do not already have HTML to convert, PDFShift cannot help you produce a document — it can only convert one you already have.
There is no no-code path. Business users who want to create a proposal, invoice, or report without writing HTML have no interface to use. PDFShift is developer-only by design.
The credit-based pricing can also be unpredictable for large documents. One credit equals one conversion up to 5 MB of output. A 14 MB PDF costs 3 credits. For organizations generating large documents at volume, the per-MB math matters.
What EZdoc does differently
EZdoc generates the document from a description. Describe what you need — a vendor proposal, a batch of event certificates, a branded invoice — and AI drafts the complete structure and content in about 30 seconds. You refine it by chatting, apply brand colors, and export a print-ready PDF. No HTML to write, no renderer to configure, no template design phase.
For developers, EZdoc's REST API is available on all paid plans and returns finished documents rather than expecting finished HTML. The generation-vs-conversion distinction matters here: EZdoc's API call triggers AI generation and returns a PDF; a PDFShift API call renders HTML you already produced. Both are API-driven, but they start from different inputs.
For batch workflows, EZdoc accepts a CSV natively — each row becomes a personalized document. PDFShift requires you to supply a pre-rendered HTML string per conversion and orchestrate parallel API calls yourself.
Pricing compared
PDFShift's free tier is 50 conversions per month with a 2 MB output cap, a 30-second timeout, and no async/parallel support — useful for evaluation but constrained for production use. Paid plans: Startup $9/month (500 credits), Boost $24/month (2,500 credits), Growth $39/month (5,000 credits). Annual billing gives approximately 17% off. Overages are disabled by default but can be enabled at $0.03 per credit.
EZdoc starts with 3 free AI generations — no credit card, no file-size math. Paid plans are generation- and feature-based. API access is included on all paid plans alongside the web editor.
When to choose PDFShift
PDFShift is the right choice if you are a developer who already produces HTML — from a templating engine, a web app, or a reporting system — and you need reliable, high-fidelity PDF output from that HTML. It is a focused, well-built rendering utility. If the HTML already exists and the problem is just converting it to PDF at scale, PDFShift is purpose-built for that.
When to choose EZdoc
EZdoc is the right choice if you want the document without building the HTML first. If your team does not own HTML templates, if you want AI to generate content and structure rather than just render it, or if you need non-developers to create and run document workflows without code, EZdoc covers that ground. For native CSV batch generation, for 171+ pre-built templates, and for AI-generated one-offs, EZdoc starts where PDFShift's scope ends.

Questions, answered plainly
Does EZdoc replace PDFShift for converting existing HTML to PDF?
Not directly. PDFShift is a Chromium-based renderer that accepts arbitrary HTML or URLs — useful when your system already generates HTML and you need pixel-perfect PDF output. EZdoc's model is generation, not rendering — you describe the document and it produces the HTML and PDF together. If you specifically need to convert HTML you already produce, a pure HTML-to-PDF service is the right fit; if you would rather skip writing that HTML, EZdoc handles both steps.
Is there an EZdoc API for developers?
Yes. EZdoc's REST API is available on all paid plans and supports sync and async document generation with webhooks. You drive generation from your application without building or hosting an HTML template — EZdoc returns a finished PDF.
How does PDFShift's credit-based pricing work?
PDFShift charges one credit per conversion up to 5 MB of PDF output. A 14 MB PDF consumes 3 credits. Paid plans start at $9/month for 500 credits (Startup), $24/month for 2,500 credits (Boost), and $39/month for 5,000 credits (Growth). The free tier gives 50 conversions per month with a 2 MB file limit and a 30-second timeout.
Does PDFShift have templates or a document editor?
No. PDFShift has no templates and no visual editor of any kind. It is an API-only tool — you supply the HTML and CSS, it produces the PDF. If you need templates, a library, or an AI-generated starting point, that is outside PDFShift's scope.
