Is my PDF uploaded to a server?

No. Everything runs in your browser using pdf-lib. Your files are never uploaded to any server or transmitted anywhere.

Does the order of files matter?

Yes. Files are merged in the order shown in the list. Use the up/down arrows to reorder them before merging.

Is there a file size or page count limit?

There is no hard limit imposed by the tool — it is only constrained by the memory available in your browser. Very large PDFs (hundreds of pages or high-resolution images) may be slow to process.

Will bookmarks and annotations be preserved?

Pages are copied with their content intact, but embedded bookmarks, interactive form fields, and some annotations may not be preserved in the merged output.
