Combine any number of PDFs into one file, in the order you choose. Contracts, scans, receipts, chapters: drop them in, drag them into sequence, and download a single document. Nothing is uploaded; the merge happens in your browser, so it works the same for a two-page letter and a 400-page report.
How it works
- Drop your PDFs in, or click to choose them.
- Use the Up and Down buttons to set the order.
- Click Merge and download. The combined file lands in your downloads folder.
Questions about merge pdfs
- Is there a limit on how many files I can merge?
- No fixed limit. Everything happens in your browser's memory, so a few hundred megabytes in total is the practical ceiling, less on a phone.
- Do fillable forms survive the merge?
- Form fields are flattened: the filled-in values stay visible as printed text, but the fields are no longer editable. Bookmarks do not carry over.
- Do my files get uploaded?
- No. The page ships with a browser security policy that blocks network requests, so the files cannot leave your device.
