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 — 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 — no scripting a loop 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 — 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.
