Free PDF tool

Merge multiple PDFs into one

Drop your files, reorder them with a click, and download a single combined PDF. Everything runs in your browser — your files never leave your device.

Privacy first. Your files never leave your browser — nothing is uploaded to our servers.

Drop PDFs here or click to upload

Add 2 or more files. Reorder them to control the final page order.

Beyond the free tool

What we can do for you

This tool patches PDFs after the fact. TemplateFox generates them right the first time — from your data, on demand, at scale.

Generate fresh PDFs from templates

Design once in our editor, fill with JSON, get a perfect PDF every time — no patching, splitting, or rotating needed.

Automate via API or no-code

One REST call, native Zapier / Make / n8n / Bubble nodes, or our MCP server for AI agents. Generate PDFs from any workflow.

Built for scale and reliability

Invoices, receipts, certificates, reports — generate thousands per day with consistent layout, fonts, and metadata.

Frequently asked questions

Are my files uploaded to a server?

No. The merge happens entirely in your browser using pdf-lib. Your PDFs never leave your device.

How many PDFs can I merge at once?

There is no hard limit, but performance depends on your device's RAM. Most laptops handle 50+ files without issue.

Will the output have a watermark?

Never. The output is a clean PDF identical in quality to your inputs.

Can I merge password-protected PDFs?

We try to load them, but encrypted PDFs may fail. Remove the password in your PDF reader first, then merge.

What if I need to merge PDFs automatically?

If you generate PDFs from data (invoices, receipts, reports), TemplateFox lets you create them already merged — straight from your API or Zapier/Make/n8n workflow.

Does the page order match what I see here?

Yes. Pages are written to the output in the exact order of the file list. Drag the rows or use the arrows to reorder before clicking merge.
No-code automation

Do you need automation?

Stop editing PDFs by hand. Connect TemplateFox to Zapier, Make, n8n, Airtable or Bubble and generate PDFs from any workflow.
