Merge PDF
Combine multiple PDFs in your chosen order locally in the browser.
Merge PDF is a browser-based PDF combiner for contracts, scans, class handouts, application packets, and other small document batches. Choose multiple PDFs, review page counts, move files into the right order, and download one combined file. Processing runs locally with JavaScript and pdf-lib; email delivery, if selected, can send the generated merged file.

Real examples
Contract packet cleanup
A sales coordinator combines a quote, main agreement, payment terms, and signature page into one ordered PDF, reducing the chance of missing attachments when sending the packet to a client.
Scanned record archive
An admin merges separately scanned receipts, forms, and proof documents into one file before uploading it to an internal system, keeping the sequence clear for later review.
Class material bundle
A teacher combines handouts, exercises, and extra reading into one PDF so students can download a single file and follow the material in lesson order.
Good to know
- Very large PDFs or documents with many pages can use significant browser memory; merge in smaller batches if the page becomes slow.
- Password-protected, edit-restricted, or damaged PDFs may not load or merge correctly.
- The tool creates a new PDF download and does not modify the original files on your device.
FAQ
- Are my PDFs uploaded?
- Source PDFs are not uploaded for merging because the merge runs in your browser. If you choose email delivery, the generated file may enter FunnyTools' Brevo delivery flow.
- Can I change the merge order?
- Yes. Use Move up and Move down after choosing files. The output follows the visible list order.
- Does this change my original PDFs?
- No. The tool creates a separate download and does not modify the files on your device.
- Why can large PDFs take longer?
- Everything runs locally, so large files and long documents depend on browser memory and device performance.
