How to Merge PDFs: Simple Methods That Work

Why Merge PDFs?

Ever had a client send you a contract in 5 separate PDF files? Or wanted to combine all your tax documents into one neat package? That's where merging comes in handy.

I've merged hundreds of PDFs over the years — for work projects, personal documents, you name it. Here's what actually works.

Method 1: iLovePDF (Best Online)

This is my go-to for quick merges:

  1. Go to ilovepdf.com/merge
  2. Click "Select PDF files"
  3. Choose all the files you want to combine
  4. Drag to reorder if needed
  5. Click "Merge PDF"
  6. Download your merged file

Pros: Free, fast, no account needed

Cons: File size limits on free plan (100MB)

Method 2: PDF2Go

Another solid online option:

  1. Visit pdf2go.com/merge-pdf
  2. Upload your files
  3. Arrange the order
  4. Click "Merge"

Method 3: Mac Preview

If you're on a Mac, you don't need any extra tools:

  1. Open the first PDF in Preview
  2. Go to View → Thumbnails
  3. Select the pages you want from other PDFs
  4. Drag them into the sidebar of your first PDF
  5. File → Export as PDF

Method 4: Command Line (For Techies)

Developers and power users can use ImageMagick or similar tools. It's fast and can be automated.

Common Problems and Solutions

File too big? Try reducing PDF size before merging

Wrong order? Most tools let you drag and drop to reorder

Protected files? You'll need to unlock them first

Final Thoughts

Merging PDFs is one of those tasks that's way simpler than people think. You really don't need fancy software — the free online tools handle 99% of use cases perfectly.
