How to use: Merge PDF Files

Combine multiple PDFs into one file in any order, without uploading them anywhere. Everything happens inside your browser on your own device. Your files, numbers and text are never uploaded, there are no accounts, cookies or trackers, and closing the tab removes the data.

Common uses

Combining a passport scan, visa and ticket into one application PDF
Joining monthly statements into one file
Putting chapters or scanned pages together in order

Step by step

Choose PDF files.
Reorder with the Up/Down buttons.
Press Merge and download.

Worked example

For example, add three PDFs, reorder them, and press merge; the pages are copied as they are, so text stays sharp and selectable.

Tips for better results

Check the page count and order in the preview before saving. Very large or scanned PDFs need more memory, so on an older phone close other tabs first. In most PDF tools, when you finish, the Next buttons can pass the new PDF to another PDF tool, without downloading it first. The page is designed for phones first, so it works on a 375-pixel screen as well as on a desktop.

Good to know

A PDF can hold real text, which stays sharp and searchable, or scanned images of pages, which are bigger. Tools that copy pages keep the original quality; tools that turn pages into images make files smaller but the text can no longer be selected. Password-protected or damaged PDFs may not open; remove the password with the software that created it first. Your original file is never changed, a new file is saved instead.

Why a browser-based tool?

Many online tools upload whatever you give them to a remote server, process it there and send it back. That is slower on a weak mobile connection and means a copy of your document, photo or figures sits on someone else’s computer. Free Adawat works differently: the code is downloaded once, then the work happens on your phone or computer. That keeps personal papers such as passports, visas, salary slips and contracts private, and it also means there is no queue, no file count limit and no waiting for a download link.
