Frequently asked questions
How many PDFs can I merge at once?
There is no fixed limit. You can merge as many PDF files as your browser memory allows. Most modern devices handle dozens of files without issue.
Will the merged PDF preserve hyperlinks and bookmarks?
Yes. Our local merge engine preserves the internal structure of each PDF, including hyperlinks, bookmarks, form fields, and embedded fonts.
Can I rearrange the order of PDFs before merging?
Absolutely. After uploading, you can drag and drop files to reorder them. The final merged document follows the exact sequence you set.
Is the quality of the merged PDF the same as the originals?
Yes. Merging PDFs does not alter or compress the content. Each page retains its original resolution and formatting.
