Merge PDF

PDF tools

Add multiple PDFs, reorder them, and combine them into one file. Everything runs in your browser — your files are never uploaded.

What is this PDF merge tool?

A free, browser-based tool that combines several PDF files into a single document in the order you choose. There's nothing to install and no sign-up — and because everything runs locally in your browser, your files are never uploaded to a server.

How to merge PDFs

  1. Add your PDFs by dragging them in or clicking the upload area. You can add more files at any time.
  2. Reorder the files with the up/down arrows so the pages line up the way you want. Remove any file you don't need.
  3. Press “Merge & download” to get a single combined PDF.

Common use cases

  • Combining a cover letter, resume, and portfolio into one file to submit.
  • Joining separately scanned pages or chapters back into a single document.
  • Bundling invoices, receipts, or reports for a single tidy attachment.

Why use this PDF merge tool

Works on Windows & Mac

Runs in any modern browser, so it works the same on Windows, macOS, Linux, and even phones and tablets — no OS-specific app needed.

No install, fully online

There's nothing to download or set up. Open the page and start right away — no software, no plugins, no sign-up.

Safe & private

All processing happens locally in your browser. Your files are never uploaded to a server, so confidential documents stay on your device.

Fast — no upload wait

Because files don't travel to a server and back, there's no upload or queue. Processing starts instantly and finishes in seconds.

Print-ready quality

The original layout, fonts, and image resolution are preserved, so the result looks right on screen and when printed.

Simple to use

A clean, intuitive interface gets the job done in a few clicks — no manuals and no PDF expertise required.

PDF merge tool vs. other PDF tools

Most online PDF services — including Adobe Acrobat online, iLovePDF, Smallpdf, and Canva — upload your files to their servers, and many cap free usage or require an account. Desktop software like Adobe InDesign needs a paid install. This tool runs entirely in your browser: your files are never uploaded, there's no sign-up, and it's completely free with no usage limits.
