FAQ
Can I merge PDFs with different page sizes?
Yes — each source page keeps its own original size and orientation in the merged output; pages are not stretched or cropped to match each other.
How many files can I merge?
As many as your browser's available memory allows — there's no arbitrary tool-imposed limit, but a very large combined page count will take longer and use more memory.
Are my files uploaded anywhere?
No. Merging happens entirely inside your browser tab. Nothing is sent to any server.
Does merging change the content of each page?
No — each original page is copied into the new document as-is; only the page order and the file boundary change.
