Merge PDFs up to 150 MB

Combine multiple PDF documents into a single file. Reorder and select pages.

🔒 Your files never leave your device

Built for larger private PDFs

Up to 150 MB
No upload
Firewall friendly

Most cloud PDF tools need uploads, accounts, or free-tier caps for large files. ExactPDF processes files locally in your browser, supports PDFs up to 150 MB on this tool surface, and never adds a watermark or daily quota.

How It Works

Step 1: Add Your PDFs

Drop two or more PDFs — board packs, contracts, invoice runs, or scanned chapters. Each file can be up to ~150 MB; nothing uploads to a server.

Step 2: Reorder & Pick Pages

Drag thumbnails to set the merge order. Optional: open Preview to keep only the pages you need from each source PDF.

Step 3: Merge & Download

Click Merge — bookmarks for each input file are preserved on request. Download a single combined PDF in seconds.

Why Use This Tool

  • Local merge of large PDFs (~150 MB per input) without the 2-tasks/day cap on Smallpdf or the upload-to-cloud step on iLovePDF
  • Bookmarks per file kept on by default — perfect for tax packets, diligence rooms, and audit binders
  • Drag-and-drop ordering with live preview, so you ship the merge in the right sequence the first time
  • Zero watermarks, zero signup, zero retention — bytes stay on your device, ideal for HR, legal, and finance bundles

Common Use Cases

Merge PDF invoices and receipts for month-end close, combine Exhibit A–Z for legal or audit folders, stitch grant appendices and CVs into one application bundle, and join chapter PDFs into a single course reader. Office admins assemble onboarding packs; consultants combine slides and reports into one deliverable. When a portal demands a single PDF (visa, university admission, government tender), merge locally instead of trusting a free upload site.
