PDF Combiner & Joiner - Merge Multiple Files (Free)
Looking to combine PDF files into a single document? Our advanced PDF Merger lets you join invoices, e-books, reports, and study notes instantly. Unlike old-school converters, we offer a modern, drag-and-drop interface that works directly in your browser.
Whether you call it a PDF Binder, PDF Joiner, or Merger, our tool handles it all. Reorder pages, remove unnecessary files, and compress the final result—all without installing heavy software like Adobe Acrobat.
This is the #1 reason to choose us over iLovePDF. We do not upload your files to a server. All merging happens locally on your device using high-speed JavaScript. Your confidential data never leaves your computer.
Since we don't use a server, there are no artificial upload limits. You can combine large PDF files (100MB+) instantly without waiting for slow uploads or downloads.
Merged files can get big. Use our built-in Compression Slider to reduce the file size of your final PDF by up to 80% while keeping the text sharp.
How to Merge PDFs on Mobile & Desktop
- Select Documents: Drag and drop your PDF files into the upload box or tap to browse from your mobile storage.
- Arrange Order: Drag the thumbnails to sort them. The file at the top becomes Page 1 of your new document.
- Preview & Clean: Click the "Magnifying Glass" to check a file, or the "X" to remove unwanted pages.
- Merge & Download: Click "Merge PDFs Now" to join them. Use the "Compress" option if the file size is too large.
