Merge PDF files
Combine PDF files in the order you choose and download one document. Files stay in your browser.
How to use this tool
Choose two to ten PDFs, then use the Up and Down buttons to set their order. Select Create PDF to combine their pages. Maximum: 50 MB total and 500 pages. Password-protected files are not supported. The output preserves page content; digital signatures, bookmarks, forms and other interactive features may not survive copying. Keep the original files and check the result.
