About this tool
Combine two or more PDF documents into a single file without installing anything. Add your files, and every page from each document appears as a thumbnail so you can see exactly what you are merging. Drag pages into the order you want, rotate any page that is sideways, and add more files whenever you need to — the merge only happens once you click Merge PDFs.
How to use it
- Drop or select two or more PDF files.
- Review the page thumbnails, drag to reorder, and rotate any page that needs it.
- Add more files at any point before saving.
- Click Merge PDFs and download the combined document.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit is enforced by the tool itself. Very large files are limited only by your device's memory, since everything is processed on your computer rather than a server.
Will the page order in my original files change?
Only if you drag pages into a new order. Otherwise, pages keep the sequence they had in their original file, one file after another.
Does merging reduce the quality of my PDF?
No. Pages are copied as-is; merging does not re-encode or compress any content.
Are my files uploaded anywhere?
No. Merging happens entirely inside your browser tab. Files are never sent to a server.
