Common questions
Are PDFs uploaded when merging?
The tool is designed for browser-local processing, so files are not intentionally uploaded to a server.
Can I control the merge order?
Yes. Sort the uploaded files before merging. The output PDF follows the list order.
What if merging a large PDF fails?
Browser memory is limited. Try fewer files, close other tabs, or compress/split very large PDFs first.
