About PDF Merger
Merge multiple PDF documents into a single file. The order of the merged PDF follows the order of the files you select. All processing runs in your browser using PDF-lib.
Questions fréquentes
Is my PDF sent to a server?
No. Merging is done entirely in your browser. Your files never leave your device.
Is there a file size limit?
Very large PDFs may slow down or exceed memory in the browser. For big documents, consider splitting the merge or using a desktop tool.
