Do my files get uploaded anywhere?

No — merging happens entirely in your browser. Your PDF files are never sent to a server or stored anywhere.

Is there a file size or page limit?

There's no hard limit, but very large files (over roughly 50MB combined) may be slow to merge or could fail on some mobile devices, since everything is processed in your device's memory.

Can I merge password-protected PDFs?

No — password-protected or encrypted PDFs can't be merged. Remove the password first using your PDF reader, then try again.

Can I reorder pages within a single PDF, not just the files?

Not yet — this tool merges whole files in the order you arrange them, but doesn't currently let you reorder or remove individual pages within one PDF.

PDF Merger

Combine multiple PDF files into a single document — drop them in, reorder as needed, and download the merged file. Everything happens directly in your browser; your files are never uploaded to a server.

How it works

This tool loads each selected PDF directly in your browser and copies every page, in the order you choose, into a single new PDF document, which is then offered to you as a download. Because the merge happens entirely client-side, your files never leave your device — there's no upload, no server-side processing, and nothing is stored.

Worked example

Select two or more PDF files — for example, a cover letter and a resume — use the up/down arrows to put them in the order you want, then click 'Merge & Download' to get one combined PDF file ready to send or print.
