Frequently asked questions
Are my PDFs uploaded to a server?
No. The merge happens inside your browser using JavaScript. The combined file is assembled on your device — we never receive, see, or store your documents.
Is there a file size or page limit?
The practical limit is your device's memory. Merging a few hundred pages works fine on a normal laptop; extremely large scans may be slow on older phones.
Will the merged PDF keep quality and formatting?
Yes. Pages are copied losslessly — no re-rendering, no compression, no watermark. Text stays selectable and images keep their original resolution.
Can I change the order of files before merging?
Yes. Use the up and down arrows on each file in the list; the merged output follows the list order top to bottom.
