Frequently Asked Questions
How do I combine multiple PDF files into one?
Upload all the PDFs you want to combine — they're merged into a single document in the order you selected or added the files.
Can I control the final page order?
Yes, but indirectly — there’s no drag-and-drop reorder step, so the order your files are merged in matches the order you selected them in.
Is there a limit on how many PDFs I can merge at once?
You can merge up to 30 PDF files in a single request.
Will bookmarks and the table of contents from my original files carry over?
Page content, text and images copy over fully, but the navigation outline/bookmark panel from the original files is not rebuilt in the merged document — only the page content itself.
What happens to each file’s original page size?
Each page keeps its own original dimensions in the merged file — pages from a landscape file and a portrait file can sit side by side without being forced to match.
Can I merge a password-protected PDF?
Remove the password first with the Unlock PDF tool, then merge the unlocked file.
