Yes, all processing happens locally in your browser. No files are uploaded to servers. You can safely merge contracts, financial documents and other sensitive files without privacy concerns.

How many files can I merge?

There is no fixed limit on the number of files. Practically it depends on the machine memory — most machines handle 20-50 PDFs without problems. For extremely large files (100MB+) processing may take somewhat longer.

Are bookmarks and links preserved?

Yes, the tool preserves internal links, bookmarks, images and all formatting from the original PDFs. The merged document looks exactly like the originals put together.

Can I choose specific pages?

Yes, you can choose page ranges from each PDF — e.g. only pages 1-3 from one document and pages 5-10 from another. This is useful when you only need parts of each document.

Pdf Merger

What it does

Combines multiple PDF files into one. Choose order and page ranges. Everything happens locally in the browser.

You have multiple PDF files that need to become one document — but merging them requires either expensive software or insecure web services

The need to merge PDF files arises daily — contracts with attachments, reports with appendices, presentations with supplementary material, or invoice summaries. But most people do not have Adobe Acrobat Pro (which costs over $200/year), and free web services upload your files to unknown servers where they can potentially be read, stored or misused. For sensitive documents like contracts, financial reports and personal data this is an unacceptable security risk.

Adobe Acrobat Pro is expensive — over $200/year for a function you might use a few times a month is hard to justify for most people
Free web services are insecure — when you upload PDFs to a web service, you have no control over what happens to the files — they can be stored, analyzed or resold
Sensitive documents require local processing — contracts, financial reports, medical documents and personal data should never be uploaded to third-party servers
Manual merging is time-consuming — copying content between PDFs manually destroys formatting, loses links and bookmarks, and takes unnecessarily long time

Merge PDF files directly in the browser — fast, free and without files leaving your machine

PDF Merger combines multiple PDF files into one document directly in your browser. Drag and drop the files, arrange the order, select any page ranges and download the merged PDF — all without a single byte being sent to a server. The tool uses JavaScript-based PDF processing that runs entirely locally, so even the most sensitive documents are safe.

Local processing: all merging happens in the browser — no files are uploaded to servers, no data leaves your machine, no tracking data is collected
Drag and drop: drag PDF files into the tool and arrange the order with drag and drop — intuitive and fast without having to navigate file systems
Page range selection: choose specific pages from each PDF — e.g. pages 1-5 from document A and pages 3-7 from document B — to create exactly the document you need
Preserves formatting: all links, bookmarks, images and formatting are preserved in the merged document — no quality loss or broken layout

Features

Drag and drop: drag PDF files directly into the tool from the desktop or file manager — no file picker dialogs needed
Order sorting: drag files into desired order — first file becomes the first part of the merged document, and so on
Page ranges: choose specific pages from each file (e.g. "1-3, 5, 7-10") to include only the pages you need in the final document
Preview: see a thumbnail view of pages in each PDF before merging — so you can verify you have the correct files and pages

How it works

Drag and drop the PDF files you want to merge into the tool — or click to select files from your machine
Arrange files in desired order and select any page ranges from each file
Click "Merge" and download the merged PDF — everything is processed locally in the browser

Use cases

Office workers who need to combine contracts with attachments, reports with appendices or presentations with supplementary material into one collected document
Accountants collecting invoice summaries, receipts and financial reports in one PDF document for archiving or auditing
Students and researchers combining articles, notes and references into a collected research folder for projects and dissertations

Why use PDF Merger?

PDF merging is one of the most common document tasks, but most solutions are either expensive (Adobe Acrobat Pro) or insecure (free web services that upload your files). PDF Merger gives you the best of both worlds — free and entirely local in the browser.

Security is the biggest advantage. When you merge contracts, financial reports or documents with personal data, it is critical that the files never leave your machine. PDF Merger processes everything locally — no servers, no uploading, no risk.

Simplicity is the second biggest advantage. Drag and drop the files, arrange the order, click "Merge" — done. No registration, no installation, no watermarks, no limitations. It just works.
