File contents stay in your browser. BAOI loads pdf-lib to manipulate pages, but does not upload your documents to a conversion API.
Questions about this tool
What happens to the original file during merging multiple PDFs?
Work on a copy and keep the original until the generated PDF has been reviewed. The tool should not become your only source copy.
What should I verify after merging multiple PDFs?
Open the result and check page count, order, orientation, dimensions, visual rendering and any links or interactive elements that matter.
Can the operation affect print quality or file size?
Yes. Resizing, compression, conversion and page composition can change dimensions, image quality or file size; compare the output with the intended use.
