Merge PDF Files
Combine several PDFs into a single document — processed on your device, never uploaded.
Merge PDF
Drag rows (or use ↑ ↓) to set the order. Type page ranges like 1-3, 7 to take only some pages.
🔒 Your PDF is processed entirely in this browser tab (pdf-lib + Mozilla pdf.js) — it is never uploaded, so confidential documents stay on your device.
Runs in your browser — nothing you enter is uploaded or stored.

How it works — in four simple steps
No signup and nothing to install — it all runs in your browser.
Add your PDF files
Drag your PDFs onto the upload area or click to browse. Add them in the order you want them combined — each file's pages follow the last.
Check the order
The list shows the sequence the files will be merged in. Clear and re-add if you need a different order.
Merge
Press Merge PDFs. The tool copies every page from every file into one new document, entirely on your device.
Download
Download the combined PDF straight away, ready to email, print or upload.
Files are merged in the order shown — rename them 01-, 02-… before adding to keep the order obvious.
Features
Combine any number of PDFs
Add two or more PDF files and stitch every page into one continuous document, in the order you choose — no page limit beyond your device's memory.
Nothing is uploaded
Your PDFs are read and merged entirely inside your browser, so contracts, statements and personal records never touch a server.
No watermark, no signup
The merged file is clean — no watermark stamped on your pages, no account to create, and no daily conversion cap.
Keeps original quality
Pages are copied intact from each source file, so text stays sharp and nothing is re-compressed or degraded.
About the Merge PDF
Merging PDFs is one of the most common document chores — stitching a cover letter to a résumé, combining scanned pages, or assembling a report from several exports. Most online mergers upload your files to their servers, which is a privacy risk for anything confidential. This tool does it differently.
Choose or drag in two or more PDFs in the order you want them, and the tool loads each one, copies every page into a fresh document, and saves the combined result — all using the pdf-lib library running inside your browser. You get a download link for the merged file; nothing is ever transmitted.
Because the work happens on your device, there are no upload waits, no file-size limits imposed by a server, and no watermarks. Sensitive contracts, statements, and personal records stay entirely private.
Examples
When to use it
Assemble a single document to send
Join a cover letter and résumé, or a contract and its annexes, into one file so the recipient opens one tidy PDF instead of juggling several attachments.
Combine scanned pages
Merge pages you scanned or photographed separately — a signed agreement, an ID, a form — into the single upload a portal expects.
Build a report from exports
Stitch chapters, invoices or statements exported one at a time into a complete, ordered report.
Tips for the best results
- Order is set by how you add files. Add them in the final sequence you want; the first file's pages come first.
- Merging is lossless. Pages are copied as-is, so quality is identical to the originals — merge freely.
- Unlock protected files first. A PDF locked with an open password may need to be unlocked before it can be merged.
