Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions
About this tool
Is there a server upload?
No. pdf-lib reads and combines the files in this browser.
Can encrypted PDFs be merged?
Remove protection with an authorized PDF application first; this route does not bypass document security.
