Auto‑generate PDF certificates

Use Robolly's spreadsheet-like interface to generate personalized PDF certificates in bulk or integrate API for complete automation.

Didn’t find template for you?

Design your custom template right from the browser with Robolly’s simple editor. Or choose from 100+ templates we pre‑made and modify them to fit your needs.

From a template to hundreds of generated visuals in one click

Enter data into a spreadsheet-like interface, select templates, and hit render to auto-generate your visuals. Need to create multiple design variants in different image sizes? No problem, you can do it all at once with Robolly's datasets.

Generate visuals with API

Need to generate template-based graphics programmatically? With Robolly API, it's as easy as getting the right parameters into an URL link. You can do it manually, it works in email, or create a fully automated pipeline on your server.

  • On-demand rendering
  • Security signature
  • No-code friendly
# The image is genereated & returned synchnously, so the render URL works as source for img, meta tag, etc.
<meta name="twitter:image" content="https://api.robolly.com/templates/1/render?title=Apple AirTag&price=$29">
<meta property="og:image" content="https://api.robolly.com/templates/2/render?title=Apple AirTag&price=$29">

# Of course, you can also download the image programatically and save it for example...
const params = "certificate-holder=John doe&date=29 September 2022, 10:02";
const response = await fetch(`https://api.robolly.com/templates/3/render/pdf?${params}`);
response.body.pipe(fs.createWriteStream("./certificate.pdf"));

Efficient, time-saving and fun!

“I actually really enjoyed making my templates! It's great seeing them come together. So, the biggest benefit here is the sheer amount of time saved. It takes a little time to set up templates. But the time you save from then onward is amazing. Robolly comes with a solid bunch of good-looking pre-made templates. Datasets make it super easy to create images. Love that you can search and use images directly from there rather than having to find them elsewhere, save & upload. Google Sheets integration is brilliant and is just what I need for creating quick, on-the-fly images in a variety of different templates I've created. Cannot recommend highly enough.“

Great for generating lots of content quickly!

“I'm really pleased with Robolly. I've tried similar apps before and wasn't impressed. But Robolly was recommended to me by a few people so I thought I'd give it a try. I've used it to generate lots of content for our Facebook group which I've scheduled to post daily for the year ahead. A very small amount of work for a year's worth of content!“

An amazing tool

“What a tool. If you wish to automatically produce more designs in a short time period Robolly is the right choice. It saves us a lot of time...Use your GSheet and their API and push data into templates in a minute. Woollaaa done..“

You know you need this!

“Amazing tool! It's so easy to use and helps me create unique images in a fraction of the time. The dataset (like Google Sheet) is the best feature of this tool. It creates personalised images by you adding columns and rows to the datasets. The live preview on the left facilitates a quick preview of the images created and you can edit the template if needed. The workflow is so simple and straightforward, yet super effective. I recently used this to create images for my blog, so all my posts now have the same featured images template with the post title and excerpt. A highly recommended tool for anyone who needs to create personalised images in bulk!“
