Combine PDF files
Select two or more PDFs inside a MallowShare room and choose Merge PDFs. This keeps page dimensions and existing searchable text when the files can be processed by pdf-lib.

Merge PDF files before sharing
Merge PDF pages locally, flatten output and share a resulting PDF file using QR room sharing.
Open this tool →Processing boundaries
Up to 8 PDFs and 30 pages in total, with a 25 MB limit per input PDF.
Check before sharing
Room-based merge preserves original pages when supported; the separate basic flatten PDF operation can remove text search, forms and links.
Share
Download the merged PDF, send it into the same sharing room, or create an optional expiring direct-download QR for eligible small files.
Merge inside a room: Select at least two PDF rows, then use the contextual Merge PDFs action near the bottom of the window. For local files before sharing, open MallowConvert. The sender must stay online until peer-to-peer transfers finish.
Accuracy and privacy
MallowShare edits files in your browser until you choose to share them. Keep your original file and review the new output carefully. These compact tools are not professional document-repair, cryptographic protection, or full Office-layout engines. Compatibility depends on your browser and file type.
