What this tool does
Drop several PDF files, reorder them with the up and down buttons, then merge. Pages from each document are copied as they are, in list order, into a single PDF downloaded to your device.
Everything happens in your browser. No file is ever uploaded — your documents never leave your machine.
Limits
Password-protected PDFs cannot be read — they are flagged as errors and left out of the merge, without blocking the other files. The tool assembles whole documents; it does not let you pick individual pages.
Files are not recompressed — the output size is close to the sum of the originals — and very large documents depend on the browser’s available memory.
