Combine multiple PDF files into one document. All processing stays in your browser — nothing is uploaded.
Select the PDF files you want to merge, arrange them in the right order, and click Merge. Within seconds you get a single PDF with all pages combined — completely free, no account needed, and with a privacy guarantee: your files never leave your device.
Unlike other PDF tools that upload your documents to a server, this merger runs entirely in your browser using the pdf-lib library. Whether you're combining invoices, merging scanned contracts, or putting together a presentation, the process is instant, private, and there's no file size limit.
Free online utility tools. No signup. No tracking.
