About merging PDFs
Combining PDFs is the everyday job of assembling a contract from its appendices, a report from its sections, or a set of scanned receipts into one file to send or archive. This tool copies every page from each file — unchanged — into a single new document, so text stays searchable and images keep their resolution. Because the merge happens with a bundled library in your browser, your documents never leave your device. Need to trim the result? Use the split PDF tool, reorder pages with the PDF organizer, or shrink it with the PDF compressor.
Frequently asked questions

- Yes. Drag the files into the order you want, or use the up/down controls. Pages are combined top to bottom in the order shown.
- Only your device memory. Because everything runs locally, very large documents take longer and use more RAM, but there is no fixed cap.
- No. Pages are copied byte-for-byte into the new document, so text stays selectable and images keep their original resolution.
- Remove the password first (open it and re-save without protection). Encrypted files cannot be read in the browser without the password.
