Merge PDF

A PDF merger combines two or more PDF files into a single document in the order you arrange. This one runs entirely in your browser, so files are never uploaded, and merged.pdf downloads free with no watermark or sign-up. Password-protected PDFs aren't supported.

This tool combines multiple PDFs into a single document — a proposal with its annexures, scanned pages from your phone, monthly bank statements, or a set of invoices for your accountant. Choose your files, arrange them in the right order with the up and down arrows, and click merge. The combined PDF downloads instantly with every page intact, in exactly the order you set.

Unlike most online PDF tools, this one never uploads your files anywhere. The merging runs entirely in your browser using JavaScript, which means your contracts, financial documents and personal papers stay on your device from start to finish. That matters more than most people realise: a typical online merger sends your files to a remote server, processes them there, and keeps them for some retention period you have no control over. Here there is no server round-trip at all — which also makes merging fast even on a slow connection, because nothing needs to be uploaded or downloaded except your final file.

There's no file-count limit, no size cap beyond your device's memory, no watermark on the output, and no sign-up. The page order follows the file list, so arrange before merging. Password-protected PDFs can't be merged — remove the password in your PDF reader first, then merge. If you need to combine images into a PDF instead, use the JPG to PDF tool from the related tools below once you're done here.
