Merge PDF Online Free — Combine PDF Files

Combine multiple PDF documents into one file for email, printing, or archiving. PdfPeaks merge tool runs in your browser — upload files, drag to reorder, and download a single PDF that preserves fonts and embedded images from each source. No Acrobat install or account is required for standard use.

How It Works

Using the merge tool takes three steps. Upload two or more PDFs, arrange them so the first file becomes the opening pages of the packet, then merge and download. Password-protected inputs may need Unlock PDF first; large batches take longer depending on page count.

  • Step 1 — Upload: Add PDFs one at a time or in batch (up to 100 MB each).
  • Step 2 — Reorder: Drag files so chapters, invoices, or scans appear in the correct sequence.
  • Step 3 — Download: Save the combined PDF, then optionally compress it for email limits.

Security & Privacy

Files are encrypted in transit and deleted after processing — see our Privacy Policy for details.

  • Education: Merge lecture handouts and assignments into one study packet.
  • Scans & receipts: Join phone-scanned pages into a single archive before sharing.
