PDF Merge

Combine Multiple PDFs into One Document

Need to merge files into one PDF? Our PDF Merge tool lets you upload multiple PDF files, reorder them with simple drag-and-drop, and combine them into a single document — all directly in your browser. Merge two PDF files into one, join dozens of reports, or assemble scanned pages into one file. No server uploads, no sign-ups, no watermarks, and no Adobe Acrobat required.

The tool uses the pdf-lib library to read and combine PDF pages entirely on the client side. Simply add your files, arrange them in the desired order, and click merge. The resulting PDF preserves all pages, formatting, and content from each source file. Perfect for combining reports, contracts, scanned documents, or any PDF files you need in one place.

Powerful PDF Merging Features

How to Merge Files into One PDF

Combining separate PDFs into a single file is the most common PDF task there is — assembling a report from several exports, joining a contract with its appendices, or bundling scanned pages into one document. To merge files into one PDF here, add all your PDFs, drag them into the order you want, and click Merge PDFs. Every page from every file is copied, in order, into one new document you can download instantly.

There's no page limit and no file-count limit — merge two PDF files into one, or combine fifty. Because the merge runs locally with pdf-lib, even large documents are joined in seconds, and nothing is uploaded to a server. The original files are never touched; the tool builds a brand-new merged PDF from copies of their pages.

How to Merge PDFs on Mac (Preview)

macOS can merge PDF files on a Mac using the built-in Preview app — no download needed. Here's how to merge two PDF files into one on Mac:

Preview works, but it's fiddly with many files and offers no drag-to-reorder file list. The merge tool at the top of this page does the same job on any Mac — macOS Ventura, Sonoma, or older — right in Safari or Chrome, with a clean reorderable file list and a one-click download. It's the fastest way to merge PDF documents on Mac without opening each file by hand.

How to Merge Images (JPG/PNG) into One PDF

This tool merges PDF files, so to combine images into one PDF you first turn the pictures into PDF pages, then merge them — a quick two-step workflow that keeps everything free and in your browser:

1. Convert your photos to PDF with our JPG to PDF or PNG to PDF converter. You can turn several images into a single PDF, or one PDF per image.
2. Bring those PDFs back here, add any other documents, drag them into order, and click Merge PDFs.

This is how you merge multiple images into one PDF alongside existing documents — for example, adding scanned receipts (JPG) to a typed expense report (PDF), or placing photos between chapters. Everything stays on your device; no image or document is uploaded.

How to Merge Word Documents into One PDF

To merge Word documents into one PDF, convert each .docx file to PDF first, then combine them here. This preserves the exact layout of every document and gives you a single, universally readable PDF:

1. Convert each Word file with our DOC to PDF tool.
2. Upload the resulting PDFs here, arrange them in the right order, and click Merge PDFs to get one combined document.

It's the reliable way to merge two Word documents into one PDF (or ten) — ideal for combining a cover letter with a CV, stitching together report sections written by different people, or turning a folder of memos into a single file. You can mix Word-sourced PDFs with regular PDFs in the same merge.

Merge PDFs on Windows, Linux & Chromebook

Because this is a browser-based tool, you can merge PDFs on Windows, Linux, or a Chromebook without installing anything — no Adobe Acrobat, no desktop app, no command line. It runs the same in Chrome, Edge, Firefox, and Safari across every operating system. Linux users who'd otherwise reach for pdfunite or pdftk, and Chromebook users with no native PDF editor, get a simple drag-and-drop merge that works entirely offline once the page has loaded — and your files never leave the device, unlike most online PDF mergers.

Combine Scanned Pages & Batch-Merge PDFs

Scanners often save each page as a separate PDF, leaving you with a folder of one-page files. To merge scans into one PDF, add every scanned page here, drag them into the correct order using the file list, and merge — the result is a single, tidy document instead of a dozen loose files. It's the quickest way to turn a stack of scanned receipts, signed forms, or ID pages into one shareable PDF.

Need a batch PDF merge? There's no file-count limit, so you can drop in an entire batch at once. If your PDFs live in Google Drive, Dropbox, or OneDrive, download them to your device first (cloud files aren't stored locally until you do), then add them here. Because the merge happens in your browser, even a large batch is combined in seconds without uploading anything to a third-party server — a real advantage when the documents are confidential.
