Generate hundreds of PDFs in seconds

You’ve probably tried clunky document generators or had to manually update designs for every minor change. It’s frustrating and doesn't scale – especially when your business needs hundreds or thousands of PDFs generated per month.

Robolly’s PDF generation API handles all the heavy lifting. Feed in your data, pick a template, and let our service promptly return perfect PDFs.

Powerful API – Simple as an URL

Developers love how straightforward it is – just one simple HTTP GET request with your template ID and data, and out comes a PDF. You can do it manually, it works in email, or create a fully automated flow.

# For example, to generate a PDF certificate with a name and date, you could use:
curl "https://api.robolly.com/templates/12345/render.pdf?name=John+Doe&date=19+July+2025"

# Of course, you can also download the image programatically and save it for example...
const params = "name=John Doe&date=19 July 2025";
const response = await fetch(`https://api.robolly.com/templates/12345/render/pdf?${params}`);
response.body.pipe(fs.createWriteStream("./certificate.pdf"));

For advanced use, a full RESTful API is available (list templates, elements, renders etc.) – check out API documentation.

Efficient no‑code integrations

Non-developers aren’t left out either: Robolly integrates natively with Google Sheets, Airtable, Zapier, Make and N8N for no‑code PDF generation. Imagine generating beautifully formatted proposals or certificates right from a spreadsheet or automation workflow – no scripting required.

Render forms

No‑code PDF generation for everyone

Thanks to Render Forms, you can share PDF templates non‑technical teammates or even your clients and give them the power to generate production‑ready PDFs, without touching your codebase or the template editor.

  • Share a simple link, not source files

  • Save hours of back‑and‑forth

  • Keep design control

  • White‑label option

Datasets

Bulk generation made simple

When you need to generate many PDFs at once, Robolly’s Datasets feature has you covered.

Datasets is a spreadsheet‑like interface for bulk rendering. It's just like filling in a Google Sheet, you enter different data rows (or import from CSV) – say a list of names and scores for student certificates. Then with one click, Robolly generates your PDFs, even allowing multi‑template and multi‑format outputs in the same batch.

Datasets have integration with 5 million+ royalty‑free image library, so adding high‑quality photos to documents is a breeze.

Signed URLs & Hidden render links

Security for your for documents

All render requests are made over HTTPS, and you have fine‑grained control over access. Secure your templates with Hidden render links and Signed URLs. By toggling “Require render link authentication,” you decide if a template’s link can be used openly or must be signed/authorized.

Plus, Robolly’s cloud infrastructure is built for high‑volume, concurrent generation – whether you’re creating 10 or 10,000 PDFs, the service scales seamlessly.

I'm impressed. Thumbs up!

“First impressions count, and I'm impressed… Great to see they thought of securing the API with a hash too, and that's not an afterthought… Thumbs up!“

Jean-Jacques Halans

Web developer & security specialist

And remember, Robolly isn’t limited to PDFs: it’s an all‑in‑one platform for rendering images, PDFs, and even videos. One platform, all your media automation needs.
