Add two or more PDF files, put them in the order you want, and combine them into a single document — processed entirely on your device.
You can add more files at any time. Nothing is uploaded.
Drag in every PDF you want combined. Order them with the arrows on each row.
Your browser copies every page, in order, into one new PDF using pdf-lib.
Save the combined file. The originals and the merged copy never left this tab.
No fixed limit is enforced by the tool itself. In practice, very large numbers of files or very large PDFs are limited only by your device's available memory, since everything is processed in your browser rather than on a server.
No. Pages are copied directly from the source files rather than converted to images, so text stays sharp and selectable, and embedded images keep their original resolution.
Password-protected PDFs need to be unlocked first. Merging works on files that either have no open password or have already been opened and re-saved without one.
Yes — pages appear in the merged PDF in the same order as the files are listed. Use the up and down arrows next to each file to reorder before merging.
