Tips & Best Practices

  • You can merge up to 20 PDF files at once for best performance.
  • Arrange files in the desired order before merging - this determines the page sequence.
  • All pages from all PDFs will be included in the merged document.
  • The original files remain unchanged - you get a new merged file.
  • Large files may take longer to process - please be patient.

Why Merge PDF Files?

Merging PDF files is essential when you have multiple documents that belong together. Whether you're combining invoices, reports, or chapters of a book, merging them into a single file makes them easier to share, store, and print. It reduces clutter and ensures that all related information is kept in one place.

Merge PDFs: Free Adobe Acrobat Alternative

Adobe Acrobat is a powerful tool, but its subscription cost can be prohibitive for occasional users. To merge PDFs in Acrobat, you typically need the paid 'Pro' version:

  1. Open Acrobat.
  2. Go to Tools > Combine Files.
  3. Add files and click Combine.

Why Pay? Use ToolDeckHub Instead.

Our tool offers the same core functionality—combining multiple PDFs into one—completely free. You don't need to sign up, download huge software, or pay a monthly fee. It's the perfect lightweight alternative for students, freelancers, and small businesses.

How to Merge PDFs on Mac (Preview Method)

Mac users have a built-in tool called Preview that can handle basic merging:

  1. Open your first PDF in Preview.
  2. Choose View > Thumbnails.
  3. Drag and drop the second PDF file into the sidebar where you want it to appear.
  4. Save the file.

Note: This method can be clunky if you have many files to merge. Our tool handles bulk merging much faster.

How to Merge PDFs on Windows (Without Software)

Windows doesn't have a native 'merge' button, but you can use a trick if you have all files ready:

  1. Highlight all the PDF files you want to combine.
  2. Right-click and select Print.
  3. Choose Microsoft Print to PDF as the printer.
  4. Click Print, and Windows will ask you where to save the single combined PDF file.

Limitations: You have less control over the order of pages compared to using a dedicated drag-and-drop tool like ours.

Is it Safe to Merge PDFs Online?

Security is a top priority at ToolDeckHub. When you use our Merge PDF tool:

  • Client-Side Processing: For many operations, we strive to process files directly in your browser.
  • Auto-Deletion: If files are uploaded for processing, they are automatically deleted from our servers shortly after conversion.
  • Encryption: We use SSL/TLS encryption to protect your data during transfer.

We do not look at, read, or share your document contents.
