When it helps
Use it when a scanned contract was saved one page per file, when a quote, a certificate and a bank statement must be sent as one attachment, or when a cover page needs to go in front of a report. The order of the list is the page order of the result, so one look at the list before merging is all the checking you need.
Each page keeps its own size and orientation, so portrait letters and landscape drawings can be mixed. Text and images are copied as they are and are not compressed again, so quality does not change.
Why your files stay on your device
Most online PDF services upload your document to a server, process it there and delete it later. This tool downloads the merging code to your browser and runs it on your own computer or phone. Contracts, payslips and ID documents can be combined without sending them anywhere. Once the page has loaded, merging keeps working even if the connection drops.
Tips for getting the order right
If you prefix file names with 01, 02 and select them together, they usually arrive in that order. After that, just remember that the top of the list is the first page of the result. To fix the order of a few pages afterwards you do not have to merge again: move them in Reorder PDF pages, and add continuous numbering with Add page numbers.
Good to know
- Password-protected PDFs cannot be opened. Remove the password first.
- Bookmarks (outlines) and fillable form fields of the originals are not carried into the merged file. The page content is unchanged.
- There is no fixed size limit, but files of several hundred megabytes can be slow depending on your device memory.
