merged.pdf
Use cases
Collect a report and its appendices in one file, put scanned pages back together, or send one attachment instead of five.
Limitations
Large files need more memory, so merging many big documents can be slow. Form fields, bookmarks, and digital signatures may not survive the merge. An encrypted file must be unlocked first.
Privacy
The file is processed in your browser and is not uploaded for conversion. Only share exported files with services you trust.
Frequently asked questions
Can I change the page order?
Reorder the files in the list before you merge. Pages follow that order.
Is there a limit on how many files I can merge?
There is no fixed count. The practical limit is the memory of your device, and every file must stay under 100 MB.
Are my PDF files uploaded?
The merge runs in your browser. The files are not uploaded.
