Merging PDFs is one of the most common document tasks — combining invoices into one file for accounting, stitching together scanned pages into a single report, or assembling a portfolio from separate chapters. This tool runs the merge directly in your browser using open-source PDF libraries, so your files are combined instantly and never uploaded anywhere. Add as many PDFs as you like, reorder them, and download the combined file in seconds.
Traditional PDF utilities require uploading confidential documents to remote servers, queueing your tasks behind paywalls, or downscaling your files with watermarks. By executing operations locally via client-side WebAssembly and JavaScript, your data never leaves your computer, and processing finishes instantly without queue limits.
