🔒 Nothing you enter is sent anywhere or stored. All processing happens in your browser.

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.

How it works — in four simple steps

No signup, nothing to install — it all runs in your browser.

Step 01

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.

Step 02

Check the order

The list shows the sequence the files will be merged in. Clear and re-add if you need a different order.

Step 03

Merge

Press Merge PDFs. The tool copies every page from every file into one new document, entirely on your device.

Step 04

Download

Download the combined PDF straight away, ready to email, print or upload.

How it works

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

Cover letter + résumé → one application.pdf.

Several scanned receipts → a single file for expenses.

Chapters exported separately → one combined document.

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.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Merging happens entirely in your browser with JavaScript, so your files never leave your device.

Does it add a watermark or limit pages?

No watermarks and no artificial limits — the output is a clean PDF of all your pages.

In what order are files merged?

In the order they appear in the list, which follows the order you added them.

Can it merge password-protected PDFs?

It attempts to ignore basic encryption, but files locked with an open password may need to be unlocked first.
