You have multiple PDF files and need them as one document. Maybe it is a job application with separate files for your CV, certificates, and ID. Or a loan application with various documents. This tool merges them in seconds — free, no login, no watermark.
PDF Merger
Merge unlimited PDF files into one — all processing in your browser, files never uploaded
Try this free toolHow to merge PDF files — step by step
- Open PDF Tools and select the "Merge PDFs" tab
- Click the upload area or drag and drop your PDF files
- You can upload multiple files at once — they appear as a list with file names and page counts
- Check the order — drag to rearrange if needed
- Click "Merge X PDFs" button
- Your combined PDF downloads automatically in a few seconds
The total page count of your merged PDF is shown before you download, so you can verify all files are included.
Why your files never leave your device
Our PDF merger uses pdf-lib, a JavaScript library that runs entirely in your browser. When you select your PDF files, they are read by your browser's JavaScript engine locally — nothing is sent to any server. Your confidential documents (ID cards, salary slips, legal documents) stay completely private.
You can verify this: open PDF Tools, disconnect from the internet, then try merging — it works perfectly because no internet connection is needed.

What to do if merged PDF file is too large
After merging, if your combined PDF exceeds the portal's upload limit:
- Use the "Compress PDF" option in PDF Tools to reduce file size
- Choose "Screen" quality (72 DPI) for maximum compression, or "Ebook" (150 DPI) for a balance of size and readability
