PDF Merge

Need to combine multiple PDF documents into one? This PDF Merge tool lets you select multiple files, reorder them, and download a single merged PDF. No file size limits, no watermarks, no account required.

The PDF Merge tool is perfect for professionals who need to consolidate reports, invoices, or contracts into a single document. Accountants use the PDF Merge tool to combine monthly financial statements into quarterly or annual reports for clients. Real estate agents merge disclosure forms, inspection reports, and contracts into one package for closing. Students can combine lecture notes, assignments, and reference materials into organized study documents for exam preparation.

This PDF Merge tool preserves all content from the original files, including vector graphics, embedded fonts, and form fields. The drag-and-drop interface makes it simple to add files in bulk by selecting multiple PDFs at once. You can reorder documents using the up and down arrows in the file list before merging. The summary row displays the total page count and combined file size to help you estimate the final document size.

For best results with the PDF Merge tool, ensure your source PDFs are not password-protected or encrypted with restrictions. Organize your files in the desired page order before clicking the merge button to save time. Very large PDF files with high-resolution images may take a few seconds to process in the browser. The merged output retains the original page dimensions, so documents with different page sizes will appear with their native dimensions preserved.

All processing happens in your browser using the pdf-lib library. Your files are never uploaded to any server, ensuring complete privacy. The merged PDF preserves all formatting, images, and text from the original files.
