Mobile merging is mostly about order
On smaller screens, drag and drop may be less comfortable than buttons. LiftPDF keeps move controls available so you can still put files in the correct order before merging.
Use clear file names in the Files app when possible. That makes it easier to identify the right sequence on mobile.
Where the result is saved
Your browser controls where downloads go. On iPhone, the merged PDF is typically available through the Downloads folder in Files, depending on your Safari settings.
Privacy and browser processing
LiftPDF merges PDFs in your browser for supported files. The pages are copied locally into a new document, so the workflow does not require a document upload API.
That matters for contracts, invoices, reports and personal records. You still need to use good judgment with sensitive files, but avoiding a server upload is a practical privacy advantage.
