merge pdf
Merging PDFs usually means two things at once: concatenating the files and also getting the page order right, because the order the files were saved in is rarely the order you actually want. This page opens the workbench with the merge panel front and center: load the PDFs, drag the thumbnails into the right order (including moving pages between different files) and download a single PDF.
Dragging the attachment A pages to right after the cover sheet, if they need to land in the middle of the contract instead of at the end, is the same drag action as reordering within a single file.
The thumbnail grid shows every page from all three files side by side, so you can compare and reorder them visually before merging.
No. Reading, assembling, rotating and splitting the PDFs all happens entirely in your browser, using pdf.js to render the thumbnails and pdf-lib to assemble the output files. No byte of the content is ever sent to a server, which is also why the tool can work with password-protected PDFs without asking anyone but you for the password.
There is no fixed file or page limit enforced by the tool; the practical limit is your browser's own memory, since all processing happens locally. Documents adding up to a few hundred pages work normally.
No, both the reading and the final assembly happen entirely in your browser, using the pdf.js and pdf-lib libraries, with no content ever sent off your device.

All processing happens in your browser: the loaded PDFs, the thumbnails and the assembled output files are never sent to a server. Closing or reloading the tab discards the workbench.
