Merge PDF Files

Combine multiple PDFs into one unified document.


Merge PDF allows you to combine multiple PDF documents into a single file directly in your browser. Perfect for organizing invoices, reports, or ebook chapters into one cohesive document.

If you have a large document that needs to be broken down instead, use our Split PDF tool. For rearranging pages within a single file, try Organize PDF.

Why use Client Tools?

  • Privacy-First & Secure: All processing happens directly in your browser. We never upload your files to any server.
  • Corporate Grade Security: Ideal for handling sensitive documents, contracts, and NDA-protected images. Since data never leaves your device, it is impossible for third parties to intercept it.
  • No Limits: Convert as many files as you want, of any size (limited only by your device's RAM).
  • Fast & Offline Capable: Works instantly without waiting for network uploads.

How it works

Unlike other converters that require you to upload your files to a cloud server (which creates a privacy risk), Client Tools uses advanced WebAssembly technology to run professional image processing software directly inside your web browser.
