Edit the source. Watch it render.
This runs against the live API, right now. Change the markup on the left, render the document on the right. Ten free renders a day here, no account. Grab a free key for 500 a month.
Hit Render to see your PDF appear here.
One call in. A rendered document out.
No print servers, no font wrangling, no queue to operate at month-end.
- 01
SEND
POST your HTML, a URL, or a saved template with JSON data. Plain curl, or the Node and Python helpers.
- 02
RENDER
We render in an isolated, locked-down environment. Fonts, page breaks, headers, and footers are handled for you.
- 03
RETURN
The raw PDF streams back in about a second, ready to hand to your user or save to your storage. Add a flag to get a hosted URL with a retention window too.
- 04
KEEP
Documents stay retrievable based on your plan: one day on Hobby, up to two years on Scale. Re-download or stream them whenever you need.
You could build this yourself.
Your own renderer or a third-party library: they all work, until they do not. Here is what the tradeoff actually looks like.
Self-hosted
- A rendering dependency to install, version-pin, and keep updated
- Font loading issues on Linux servers
- Memory leaks at high volume
- Crashes on month-end spikes
- You own every outage
- Pages that cut wrong at print boundaries
- 0 lines of your product shipped
Works until it does not.
Other PDF APIs
- Credits and size multipliers
- Overage charges with no warning
- Rate limits hidden in the fine print
- No free tier worth testing with
- Support tickets into the void
- Vendor lock-in via proprietary template DSLs
- Migration pain when pricing changes
Predictable until the bill.
PDFPipe
- One POST request
- Plain HTML you already know
- Flat monthly price, no credits
- 500 free docs forever to test with
- Founder answers support personally
- 14-day refund, no questions
- API key in seconds, not a ticket queue
Predictable, permanently.

Before you wire it in.
What do you do with the HTML and PDFs I send?
Renders run in an isolated environment with no stored credentials. By default your PDF is streamed back and not retained. Storage only happens when you explicitly set store: true, and then only for your plan's retention window, after which it is deleted automatically. Your document content is never read, trained on, or shared. See the security page for the full detail.
What happens if a render fails or times out?
Every render either returns a valid PDF or a structured error with a clear code. There are no half-rendered files and failed requests do not count against your monthly quota. Median render time is under three seconds. If you need a guaranteed response-time commitment in writing, that is covered on Scale and above.
What happens if I go over my monthly limit?
Requests that exceed your limit return a clear 402 error so your code can handle it gracefully. You can upgrade at any time and your limit resets immediately. We never silently drop requests or surprise you with overage charges.
Is there a refund policy?
Yes. If you are not satisfied within the first 14 days, email [email protected] and I will refund you in full, no questions. After that, you can cancel any time and keep access through the end of your billing period.
Can I not just render PDFs myself?
You can, and many do, until the 2 a.m. incident where it leaked memory and took checkout down with it. We handle the rendering engine, queues, retries, and font loading so your team ships product instead of operating document infrastructure.
How is this different from converter sites?
Those are for a person converting one file. PDFPipe is for software that creates documents on its own: every order, every signup, every month-end, with data filled in and nobody clicking anything.
What languages and frameworks does it support?
Anything that can make an HTTP POST request. The core API works from curl, Node.js, Python, Ruby, Go, PHP, Java, Rust, Elixir, and any other language. We publish first-party SDKs for Node.js and Python. Everything else uses plain fetch or your language's HTTP client.
Can I store documents and share download links?
Yes. Add store: true to any render request and the PDF is stored in our CDN for the retention period on your plan. You get back a document ID and a pre-signed URL. You can also query document metadata (filename, size, expiry) without downloading the full file.
Can I upgrade mid-month, and how does billing work?
Yes. Upgrade any time from your dashboard and the higher monthly limit applies immediately, no waiting for the next cycle. Billing is handled by our payment provider, which adjusts your charge for the change so you are not double-billed for the time you have already paid. You keep the same API key and the same subscription.
Why are my custom fonts not loading?
Include fonts using absolute-URL link tags or @font-face rules pointing to a hosted URL. Relative paths and local font files are not reachable from the render engine. Google Fonts links work as-is.
Why are external images or stylesheets missing?
External assets must use absolute HTTPS URLs. Relative paths and data URIs work fine. Assets behind authentication, cookies, or private CDNs will not load. When in doubt, inline critical CSS directly into your HTML.
How do I control where pages break?
Use CSS page-break-before: always or break-inside: avoid on your containers. Pass the format option (A4, Letter, etc.) in your request to set the paper size. The engine splits content automatically at the page boundary; explicit break rules let you control exactly where.
I build document pipelines for a living, and every company I have worked with ends up with the same haunted corner of the codebase: the PDF service. Nobody wrote it on purpose. Nobody wants to touch it. It falls over on the last day of the month, exactly when finance needs it.
PDFPipe is me fixing that once, properly, for everyone. Small team, no investors to impress, no plan to get acquired and sunset your integration. If it ever shuts down, you get a year of notice and an export button. In writing.
Questions go straight to [email protected]. I answer everything myself, usually same day.
