Frequently Asked Questions about Merging PDFs
Will my text remain selectable after merging?
Yes. Our merging tool does not convert your pages to flat images. It merges the internal file structures, so all searchable text, annotations, links, and forms remain fully interactive in the combined output file.
Is there a limit on file size?
We support file uploads up to 50 MB per file, which is more than sufficient for most business, academic, and personal documents. Larger files are optimized during upload to ensure fast processing.
