Frequently asked questions

Is there a file size limit?
Practical limits depend on available memory. Very large PDFs (hundreds of pages each) may be slow to process.
Does merging preserve bookmarks and hyperlinks?
Basic merging preserves text and formatting. Bookmarks and internal hyperlinks may not be fully preserved across the boundary where documents are joined.
Can I merge more than two PDFs at once?
Yes. Upload as many files as needed, arrange them in order, and merge them all in one step.
Does merging affect PDF quality?
No. The tool combines pages without re-encoding the content, so image quality and text sharpness are unchanged.
