How to use it
- Drop two or more PDF files onto the page, or click to choose them.
- Put them in the order you want with the arrow buttons. Remove any you do not need.
- Press Merge, then download the single PDF when it is ready.
Good to know
- Files are joined from top to bottom, and every page of every file is kept.
- Each page keeps its own size, so a mix of Letter and A4 pages stays as it was.
- Bookmarks and links inside the original files may not carry over to the merged file.
- Password-protected PDFs must be unlocked first. The tool tells you which file is locked.
- Big files use your device memory. If a merge fails on a phone, try fewer files at a time.
Questions
Are my files uploaded anywhere?
No. The work happens inside your browser, on your own device, so your files never reach our server. The page does load ads from third parties, but they cannot see your files.
Is there a page limit?
There is no fixed limit. Your browser memory is the limit, and a laptop handles several hundred pages without trouble.
Can I merge pictures into a PDF?
Not yet. This tool joins PDF files only.
Does merging reduce quality?
No. Pages are copied across as they are, so text stays sharp and images are not recompressed.
