When you need the same document for every customer, employee, or order, generating them one by one does not scale. ImaginePDF renders a whole dataset against a single template in parallel.
Feed it a CSV or JSON dataset, and each row becomes its own PDF, and line-item tables grow to fit the record. Submit the batch, poll until it finishes, and download a zip or pull presigned URLs for each file.
What you get
One template, many PDFs
Render an entire dataset against one design in parallel, with no loop to script yourself.
Rows grow to fit
Line-item tables expand per record, so a 2-line invoice and a 30-line invoice both render cleanly.
Zip or presigned URLs
Pull the whole batch as a zip, or fetch a presigned URL per document for your own pipeline.
Async and trackable
Submit a job of up to 100 rows, poll its status, and download when it is ready.
How it works
- 1
Build a template
Design the document once and bind the fields that change per record.
- 2
Add your dataset
Upload a CSV or POST JSON rows. Each row maps to one document.
- 3
Generate and download
Submit the batch, poll it to completion, and download the zip or pull presigned URLs.

Frequently asked questions
- How many PDFs can I generate at once?
- Up to 100 rows per batch job. For larger runs, submit multiple jobs, and each renders its rows in parallel.
- Can I use a CSV or JSON?
- Both. Upload a CSV in the dashboard, or POST JSON rows to the API. Each row maps to one PDF.
- How do I get the files?
- Download the whole batch as a zip, or pull a presigned URL for each document to feed your own system.
- How is bulk generation billed?
- One credit per generated row. Previews are free, so you can validate the template before running the batch.
