Combining multiple PDFs into one — for a complete submission, a compiled document package, or just keeping related files together — is a basic document operation that used to require software. Merge PDF handles it entirely in the browser: upload your files, drag to set the order, click to generate the combined document. Nothing leaves your device.

Anyone combining multiple documents into a single PDF — compiling a report, assembling a submission package, merging chapters, or combining a cover letter with supporting documents.

One job, done well. Merge PDF was built to solve a specific problem cleanly. No feature bloat, no ads, no distractions.

How many files can I merge?

Multiple files — no hard limit within device memory.

Does order matter?

Yes — pages from each file appear in the order you set by dragging.

Are my PDFs uploaded?

No — merging runs locally.

Does it preserve bookmarks?

Basic bookmark preservation may occur — complex bookmark structures may simplify.

Can I merge password-protected PDFs?

Password-protected PDFs must be unlocked first using the Unlock PDF tool.

Free. Instant. No sign-in. Open it and get the job done.
