Click the upload area or drag and drop multiple PDF files into the tool. You can select two or more PDF documents that you want to combine into a single file.
Rearrange the order of your PDF files by dragging them into your preferred sequence. The final merged document will follow this exact order from first to last.
Review the file list to confirm all documents are included and in the correct order. You can remove individual files or add more PDFs before merging.
Click the Merge button to combine all selected PDFs into one document. The process runs entirely in your browser and typically completes within seconds.
Download your merged PDF file once processing is complete. The combined document preserves all pages, formatting, links, and bookmarks from the original files.
Combining related documents into a single PDF simplifies file management and sharing. Instead of sending multiple attachments, you can share one comprehensive document that keeps everything organized and easy to navigate.
All PDF processing happens client-side in your browser using JavaScript. Your sensitive documents, contracts, financial statements, and personal files never leave your device, ensuring complete confidentiality.
Unlike many online PDF services that impose daily limits, file size caps, or watermarks on free accounts, this tool has no restrictions. Merge as many PDFs as you need, as often as you need, without any limitations.
The tool preserves the original quality of each PDF during the merge process. Fonts, images, vector graphics, hyperlinks, and form fields remain intact in the final combined document.
Whether you are preparing a business proposal from multiple sections, combining scanned receipts for expense reports, or assembling a portfolio, merging PDFs saves time and creates professional results.
Ensure all PDF files are finalized before merging. While the tool preserves content perfectly, making changes to the merged file requires splitting and re-merging.
For large merges with many files, process them in batches of 10-15 documents for optimal browser performance. You can then merge the resulting files in a second pass.
Check that your PDFs have consistent page sizes if uniformity is important. The tool preserves each page's original dimensions, so mixing letter and A4 sizes will result in pages of different sizes in the final document.
Name your source files descriptively before merging so the file list is easy to reorder correctly.
Drag and drop your PDF files into the upload area, arrange them in your desired order, and click the Merge button. The tool combines all PDFs into a single downloadable document instantly. No registration, no file size limits, and no watermarks. The entire process runs in your browser for complete privacy.
Yes. This PDF merger processes everything directly in your web browser using client-side JavaScript libraries. Your files never leave your computer, are never uploaded to any server, and are never stored in any cloud storage. This makes it safe for confidential documents including contracts, financial records, legal papers, and personal information.
There is no hard limit on the number of files. You can merge 2, 10, or even 50+ PDF files in a single operation. The only practical limitation is your device's available memory. For very large merges with many files totaling hundreds of megabytes, we recommend processing in smaller batches for optimal performance.
Yes, the PDF merger preserves the internal structure of each document including bookmarks, hyperlinks, form fields, annotations, and embedded fonts. The final merged document maintains all the interactive elements from the original files, ensuring nothing is lost during the combination process.
Yes, you can reorder the PDF files before merging by dragging them in the file list. Each file's pages will appear in the merged document in the order shown. If you need to reorder individual pages within a single PDF, use our PDF Split tool first to extract specific pages, then merge them in your desired sequence.
Since processing happens in your browser, the maximum depends on your device's RAM. Modern computers with 8GB+ RAM can typically handle combined file sizes of 100MB or more. For mobile devices, smaller combined sizes (under 50MB) are recommended. Very large PDF files with high-resolution images will require more memory than text-heavy documents of the same page count.
