Merge PDF files
Combine several PDFs into one file, in the order you want. It all happens in your browser: your files are not uploaded anywhere.
This tool needs JavaScript. If you still see this after a few seconds, JavaScript is switched off in your browser or the page did not load completely: turn JavaScript on or reload the page.
How to merge PDF files
- Press "Choose PDF files" or drop the files on the box. You can pick several at once.
- Put them in order with ↑ ↓, and take out any you don't need with ✕.
- Press "Merge into one file". The new file goes to your downloads.
Your files stay on your device
This tool opens the files from your device, merges them in your browser's memory and saves the new file back to your device. Nothing is uploaded and no file or file name is kept: close the page and it is all gone. Your original files are not changed.
Good to know
- Every page is copied as it is: text can still be copied and searched, and nothing loses quality.
- Bookmarks of the original files are not carried over, and fill-in form fields may stop working.
- Files locked with a password need to be unlocked first.
- It all happens in your device's memory: past about 100 MB in total, older phones may be slow or stop.
