Key Benefits & Features

Everything you need to merge PDF files, completely free

Easy PDF Merging

Upload your PDF files, drag and drop to reorder pages, and combine them into one document with a single click. It is that simple.

Page-Level Control

Every page from every PDF is shown as a thumbnail. Reorder individual pages, delete the ones you do not need, or insert new files between existing pages.

Combine PDFs and Images

Add JPEG and PNG images alongside your PDF files. Each image becomes a full page in the combined document. Great for including photos, scans, or screenshots.

100% Free PDF Combiner

Merge unlimited PDF files for free. No signup, no watermarks, no limits.

How Our Merge PDF Works

The Technology Behind It. Most PDF merge tools upload your files to a remote server, process them there, and send the result back. We do things differently. Here is what actually happens when you combine PDFs on this site:

Everything runs in your browser

We use PDF.js (the same open-source PDF engine built by Mozilla) to read and render your PDF pages directly inside your browser. Your files never get uploaded to any server. The entire process happens right on your device.

Merging with pdf-lib

The actual combining is done using pdf-lib, a JavaScript library that can create and modify PDF documents entirely in the browser. It copies pages from your source files into a new document without re-encoding or compressing anything. That is why the output quality is identical to the originals.

Images are embedded as full pages

When you add a JPEG or PNG image, it is embedded directly into the PDF as a full-size page. The image dimensions are preserved, so what you see is what you get in the final document.

Your privacy is built into the design

The site uses HTTPS/SSL encryption for everything. There is no registration, no data collection, and no cookies tracking your files. Since your PDFs never leave your device, there is nothing for us to store or leak. Close the tab and all data is gone.

Why Choose Our PDF Combiner

  • Page-Level Reordering: Most PDF merge tools only let you reorder entire files. Our tool breaks every PDF into individual page thumbnails, so you can drag and drop any page to any position. Need page 5 from one PDF before page 1 of another? Just drag it there. You have full control over the final page order.
  • Combine PDFs and Images Together: Need to include a scanned receipt, a photo, or a screenshot alongside your PDF documents? Just upload JPEG or PNG images and they will be added as full pages in the combined document. No need to convert images to PDF first.
  • No Quality Loss When Merging: We use pdf-lib to copy pages directly from your source files into the combined document. There is no re-encoding, no compression, and no quality reduction. The output is identical to the originals. Text stays sharp, images stay clear, and formatting stays intact.
  • Free Online PDF Merger, No Signup Required: This tool is completely free to use. There is no signup, no registration, and no hidden costs. Just open the page and start merging your PDFs. You can use it as many times as you want with no daily limits.
  • 100% Client-Side, Your Files Never Leave Your Device: Unlike most online PDF combiners that upload your files to a remote server, our tool processes everything right in your browser. Your PDFs never get sent anywhere. Once you close the tab, all data is gone from memory. The site uses HTTPS encryption, and we do not use cookies to track your file data.
