How to merge & extract PDFs securely

Otter Digitals makes it simple to join multiple PDFs together, or even extract specific pages from different files to create a master document. Because our tool runs directly in your browser using pdf-lib, you don't have to wait for massive files to upload or worry about data privacy.

  • Otter Logo
    Click "Upload PDF Files" or drag & drop documents into the box.
  • (Optional) Type a Page Range like 1-3 if you don't want the whole document. Leave it blank for all pages.
  • Enable Auto-TOC to automatically generate a Table of Contents page at the very beginning based on your filenames.
  • Enable Smart Duplex if you plan to print back-to-back. This ensures each document starts on a new front page.
  • Click Merge PDFs and instantly download your compiled master file!
