How to merge and split PDF files in bulk

Combine invoices or split scanned pages into separate files — reorder before merge, download ZIP after split.

Merge PDF

Use Merge PDF when you need one document from several files — monthly statements, signed pages, or vendor packets in a fixed order.

Step-by-step

  1. Sign in with a **verified** account and open Merge PDF.
  2. Drop **two or more** PDF files (up to 20 Free · 50 Premium).
  3. Use the **Merge order** list — move files **up** or **down** so the first file in the list becomes the first pages in the output.
  4. Click **Merge N PDFs**.
  5. Wait for processing, then **Download** `merged.pdf`.

Tips

  • File order matters — double-check before you submit
  • Encrypted PDFs must be unlocked first unless they open without a password in your viewer
  • Free plan: download promptly; Premium keeps the job for 7 days

Split PDF

Split PDF takes **one** PDF and returns a **ZIP** with each page as its own PDF (`filename-page-001.pdf`, etc.). Useful for splitting scanned stacks or separating chapters.

Step-by-step

  1. Open Split PDF.
  2. Upload **one** PDF (max 25 MB Free · 50 MB Premium).
  3. Click **Split PDF**.
  4. Download `output.zip` and unzip on your computer.

When split beats merge

  • You received one long scan and need to email single pages
  • You want to archive page-level files in a DAM or ERP
  • You only need a subset — consider Extract Pages instead for ranges like `1-3,5`
