Merge PDF

1. Drop your PDF files into the box above, or click it to browse and pick them. Add two or more.
2. Put them in the order you want using the up and down arrows, and remove any file with the × button.
3. Click Merge PDF and your combined file downloads on its own as merged.pdf.

Everything runs on your device, so the merge is fast and your files stay private — even with no internet once the page has loaded.

Yes. Many free PDF sites upload your files to their own servers to do the work. This tool does not. Your PDFs are read and joined right inside your browser, so they are never uploaded, stored, or seen by anyone else. That makes it a safe choice for contracts, bank statements, medical records, and anything else you would not want sitting on a stranger's server.

After you add your files, each one shows up in a list with its name and size. Use the up and down arrows to move a file higher or lower, and the × button to drop one you added by mistake. The final PDF follows the exact order of the list, from top to bottom, so put the file you want first at the top. You need at least two files before the Merge PDF button turns on.

If a PDF opens on your device without asking for a password, it will merge here without any extra steps. If a file is locked and needs a password just to open it, remove that protection first with our Unlock PDF tool, then bring the unlocked copy back here to combine it with the rest.

This tool joins PDF files, so images need one quick extra step. Turn your photos or scans into a PDF with JPG to PDF first, then add that new PDF alongside your other files and merge them all into one document. It is the easiest way to fold a signed photo, a receipt, or a scanned page into an existing PDF.

Merging copies your pages exactly, but a few document-level extras do not carry over. Here is the honest breakdown so there are no surprises:

• Every page, at full quality — text stays sharp and selectable, images keep their resolution.
• Clickable links inside your pages.
• The bookmark outline (the contents list in the sidebar).
• Interactive form fields — they are flattened to their printed look, so they are no longer fillable.
• The original file's title and author details — the merged file starts fresh.

A merged PDF is about the size of all your files added together, because every page is kept at full quality. Files with many photos or scanned pages add up fast. If the final file is too big to email or upload, run it through our Compress PDF tool to make it smaller.

Merge PDF is for joining separate files into one. If instead you need to work inside a single document — pulling pages apart, deleting a few, or shuffling their order — reach for Split PDF, Organize PDF, or Rotate PDF. Many people split a file, fix the pages they need, and then merge everything back together.

Yes. This tool works in any modern browser on iPhone, Android, tablets, and computers, with nothing to install. Add your files the same way, tap Merge PDF, and the combined file saves to your device.
