Merge PDF
Combine multiple PDF files into one document. Reorder pages as needed.
Combine PDFs into one organised document
Merging PDFs is one of the most common document tasks there is. Whether you are bundling a cover letter with a CV, stitching scanned receipts into a single expense claim, or assembling a multi-part report from separate chapters, a single PDF is far easier to email, print and archive than a scattered pile of files. Our Merge PDF tool joins any number of PDF documents into one continuous file, in the exact order you choose, without changing the content or quality of the original pages.
Unlike desktop software that needs installing and updating, this runs entirely in your web browser. There is nothing to download, no account to create and no file-size paywall waiting at the end. You add your files, arrange them, and download the combined result in seconds.
How to merge PDF files
Click the upload area and select two or more PDF files, or drag them straight onto the page. Each file appears in a list showing the order it will be placed in. Use the up and down controls to rearrange the documents until the sequence matches the final document you want. When you are happy, press Merge PDFs and then download the single combined file.
Because the pages are copied directly from your originals, fonts, images, form fields and layout are preserved exactly. Nothing is re-rendered or compressed, so a merged contract reads identically to the separate signed parts it was built from.
Your files never leave your device
All merging happens locally, inside your browser, using your own computer's memory. Your PDFs are never uploaded to a server, stored, logged or seen by anyone else, which makes the tool safe to use even for confidential contracts, medical records or financial statements. When you close the tab, every trace of the files is gone.
