About PDF Merger

How to use PDF Merger

1. Drag and drop multiple PDF files (up to 100 files, max 200MB total) into the upload area, or click to browse and select files. The file information panel displays the size and page count for each file, helping you understand the merge scope.
2. Use the up/down arrow buttons or drag files to reorder them in your preferred merge sequence. Check the real-time statistics panel showing total page count and combined file size to verify your merge parameters.
3. Click the "Merge PDFs" button to start the merge process. A real-time progress bar appears, showing which files are being processed and overall completion status. Your merged PDF automatically downloads when complete.

Benefits of PDF Merger

• [Streamline Email Attachments Professionally] Sending multiple scattered files to a recipient is considered poor business etiquette, as it forces them to open each file one by one. By using this merge tool to combine split invoices, presentation materials, or electronic receipts collected from various sources into a single logically organized file, you significantly improve the recipient's trust in your professionalism.
• [Intuitive Drag-and-Drop Reordering with Rich File Metadata] There is no need to learn complicated PDF editing software or memorize import settings. Simply drop all the PDFs you want to merge onto the screen, and they appear as a visual list showing filename, file size, and page count for each PDF. Just grab each file with your mouse and drag it into your preferred order, as naturally as sorting physical paper documents on a desk.
• [Real-Time Progress Tracking for Confident Large-Scale Merging] A live progress bar displays which file is currently being processed and the overall merge completion percentage. When combining multiple large PDF files, this real-time feedback eliminates uncertainty about processing status. Built-in file size limits (50MB per file, 200MB total, max 5000 pages) ensure reliable, stable processing even for complex multi-file merges.
• [Zero Risk of Confidential Data Leakage with Full Offline Processing] PDF files often contain sensitive information such as corporate financial statements, personal medical records, or unpublished contracts. Many free online PDF tools secretly upload and store your files on their servers. This tool's engine processes everything from file reading to merging and re-encoding entirely within your browser's local memory, without uploading to any server. It even works with internet disconnected. The probability of data leakage is physically zero.
