Merge PDF Files Online (Free & Secure)

Combine multiple PDF documents into a single file instantly. A fast, free, and secure way to organize your PDFs directly in your browser without uploading them to any server.

The Easiest Way to Combine PDFs

Managing scattered PDF files can be a headache. Whether you have separate invoices for a single project, individual chapters of a book, or scanned pages that need to be in one document, ToolMini's PDF Merger is the solution.

Our tool allows you to select unlimited PDF files from your computer and stitch them together into one organized master document. It is the perfect utility for students, professionals, and anyone who needs to keep their digital paperwork tidy.

Why Choose Client-Side Merging?

Most online PDF tools require you to upload your files to their cloud servers to process them. This takes time and exposes your data to potential privacy risks.

We do it differently. ToolMini uses advanced browser technology to merge your files locally on your device.

  • Zero Upload Time: Since files don't travel over the internet, merging is almost instant, even for large documents.
  • 100% Privacy: Your confidential contracts, bank statements, or medical records never leave your computer. We cannot see them.
  • No File Size Limits: You are not restricted by server upload caps. Merge files as large as your computer's memory can handle.

How into Merge PDF Files

  1. Select Files: Click the "Select PDF Files" button. You can hold Ctrl (Windows) or Cmd (Mac) to select multiple files at once.
  2. Review List: The tool will display the names of the files you've chosen.
  3. Automatic Processing: Our engine will immediately begin stitching the pages together in the order you selected them.
  4. Download: Once complete (usually in seconds), your new "merged_document.pdf" will download automatically.

Tips for Perfect Merging

Order Matters: The files will be merged in the order they appear in your file selection window. To ensure the correct sequence, it helps to rename your files with numbers (e.g., "01_Cover.pdf", "02_Intro.pdf", "03_Data.pdf") before selecting them.

Check Page Orientation: If one file is Portrait and another is Landscape, our merger preserves the original orientation of each page. The final document will contain a mix of both.

Consistent Quality: Merging does not degrade the quality of your text or images. The pages are copied exactly as they are in the original files.
