Frequently asked questions
Is it safe to merge confidential PDFs here?
Yes — that is exactly what this tool is for. Merging happens inside your browser via JavaScript; your documents never touch any server, making it safe for contracts and financial records.
How many files can I merge at once?
As many as your device can handle. There are no artificial limits because processing runs locally.
In what order are the files merged?
Files are merged in the order shown by their result cards. To reorder, remove them and select again in the desired order.
Are bookmarks and forms preserved?
Page content is fully preserved. Interactive features such as form fields may be flattened during merging — verify the output for critical documents.
