Merge PDF Files into One

Combine PDF files into one document in the order you choose, optionally taking only some pages from each. The files are merged in your browser, so nothing is uploaded, and there's no limit on file size or number of files beyond your device's memory.

How to use Merge PDF

Choose PDFs to merge, or drop them on the page.
Drag the files into the order you want.
To use only part of a file, type its pages next to it, e.g. 1-3, 5.
Click Merge, then Download the combined PDF.

Frequently asked questions

Is it safe to merge PDFs online?

With this tool the files never leave your device: they're combined in your browser, so nothing is uploaded or stored on a server.

How do I combine PDF files into one?

Add two or more PDFs, put them in order, and click Merge. You'll get a single PDF named after the first file.

Can I merge only certain pages from each PDF?

Yes. Each file has a Pages box. Type ranges like 1-3, 5 to include just those pages, or leave it empty for all of them.

Is there a limit on how many PDFs I can merge?

No fixed limit on files, pages or size. Very large jobs are limited only by your device's memory.

Does merging reduce quality or keep bookmarks?

The pages are copied exactly as they are, with no re-compression, so text, images and links on them look and work the same. The document info (title, author) is kept, and so are the bookmarks (the outline) and fillable form fields on the pages you keep. When merging, each file's bookmarks sit under a bookmark named after the file, and a form field whose name another file already uses gets a "_2" suffix.

Can I merge password-protected PDFs?

Not directly; protected files are skipped with a note. Remove the password with Unlock PDF first, then merge the unlocked copy.

Can I merge PDFs on my phone?

Yes. It works in mobile browsers on Android and iPhone; pick the files from your phone's storage.

Merging documents for an application

Many Indian application portals (exams, scholarships, visas, loans) ask for one PDF that holds several documents, such as an Aadhaar front and back, mark sheets and certificates. Scan or photograph each one, turn photos into PDFs with JPG to PDF, merge them here in the order the form asks for, then compress the merged PDF if it's over the portal's size limit.
