Merging PDF files is one of the most common document tasks — combining invoices, contracts, scanned pages or report sections into a single file that is easy to share and archive. Toolkit's Merge PDF tool does this instantly and privately, without uploading anything to a server.
Because the merge happens locally in your browser using your device's own processing power, it is both fast and private. Drag your files in, drag to reorder them, and download the combined PDF in seconds.
