Generate PDFs in bulk — thousands from one template thousands from one template
Build a template once, merge a spreadsheet, and EZdoc produces thousands of personalized PDFs in a single run. Every row becomes its own print-ready file, delivered as a ZIP or posted back via API.
From one template to thousands of finished PDFs
When you need a thousand personalized documents, the only sane approach is one template and a data merge. The bulk PDF generator in EZdoc does exactly that: design the document once, connect a spreadsheet of records, and generate a personalized, print-ready PDF for every row in a single run.
EZdoc maps your CSV or Excel columns into the template, renders the whole set in parallel, and hands you one organized ZIP. Names, amounts, dates, addresses, IDs — anything in your data fills the right field, so each file is unique while the design stays perfectly consistent. For production workloads, the REST API generates bulk runs programmatically.
What Is a Bulk PDF Generator?
A bulk PDF generator takes one document design and replicates it across an entire dataset, producing a separate, personalized PDF for every record. The output is the same as if you'd built each document by hand — but it takes minutes instead of hours or days, regardless of whether you're generating a hundred files or fifty thousand.
The Core Mechanic: One Template, Infinite Variants
The pattern is always the same: design a template with placeholder fields (name, amount, date, address), connect it to a spreadsheet with one row per recipient, and run the merge. EZdoc handles the rest — column-to-field mapping happens automatically, and the whole set renders in parallel so large batches complete quickly. The result is one ZIP containing every finished PDF, organized by row.
When Bulk Generation Is the Right Tool
Bulk PDF generation makes sense whenever you're producing more than a handful of identical-format documents with record-specific data. Monthly invoice runs, end-of-year certificates, compliance reports, personalized mailers — any time you'd otherwise open a template and manually change names and figures for each recipient, a bulk run replaces the work entirely.
Bulk vs. On-Demand: Knowing the Difference
Bulk generation is a batch operation — you assemble a full dataset and process it in one run. This is ideal for periodic workflows: monthly billing, semester-end certificates, annual statements. For documents that need to be generated one at a time in response to an event (a new user signing up, an order completing), the EZdoc REST API handles the on-demand case — same template, same quality, triggered per event rather than per batch.
Quality at Scale
Every file in a bulk run passes through the same renderer with the same template, so there's no degradation as volume increases. A PDF from a 10,000-row batch is identical in polish and structure to one generated by hand. The design is locked once in the template; only the merged data varies. That consistency is the main quality guarantee a bulk generator needs to provide, and EZdoc maintains it regardless of run size.
From idea to download in three steps
Design the template once — describe or upload the document and mark the fields that change per record
Merge your spreadsheet — connect a CSV or Excel file with thousands of rows — EZdoc maps every column into the design
Run it in parallel — EZdoc renders all the PDFs concurrently and delivers one organized ZIP, or posts each back via API
Everything you need, nothing in the way
Built for speed and polish — so the document is done before you would have finished formatting the first page.
Thousands in one run
Render an entire dataset at once — EZdoc parallelizes the work so big batches finish fast.
Consistent every time
One template means every file shares the same design; only the merged data changes.
Programmatic via API
Kick off bulk runs from your own systems and receive the finished PDFs back automatically.
Bulk merge from a sheet
Turn any document into a reusable template and generate thousands of personalized variants from a CSV in one run.
Tweak with AI
Refine any result by chatting — "make it warmer", "add my logo top-right", "shorten the intro". The document updates in place.
Private by default
Your documents stay yours — we never train models on your content, and you can delete anything within 24 hours.

Questions, answered plainly
What's the difference between bulk and batch generation?
They're the same idea at different scales — one template merged against many data rows. EZdoc handles both the same way: upload your spreadsheet, generate, and download the set. It parallelizes rendering so even thousands of files finish quickly.
Can I run bulk generation from my own software?
Yes. The REST API lets you submit a dataset and template programmatically and receive every finished PDF back — ideal for production pipelines that generate large volumes on a schedule or on demand.
Does quality hold up at scale?
Yes. Every file in a bulk run uses the same template and renderer, so a PDF from a 5,000-row batch has the same polish and consistency as one you'd make by hand.
What data can drive the merge?
CSV, Excel, and JSON files, plus data sent through the REST API. EZdoc maps each column or key to a field in the template automatically.
