Why merge PDFs in the browser instead of a typical online tool?

Most free PDF mergers work by uploading your documents to a server, combining them there, and sending the result back — meaning your files, which might include contracts, IDs, or financial statements, pass through someone else's servers. This tool works differently: the merge itself runs using a PDF library loaded into your own browser, so your documents never leave your device at any point in the process.

Common uses

Combining scanned pages into one document, joining a cover letter with a resume, merging multiple invoices into a single file for record-keeping, or assembling a multi-chapter report from separate PDF sections.

Frequently asked questions

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

No hard limit — since it runs in your browser rather than on a server, the practical ceiling is your own device's memory, which handles dozens of typical documents comfortably.

Does merging add a watermark?

No.

Are my files uploaded anywhere?

No — merging happens entirely in your browser.

Can I reorder pages before merging?

Yes, drag and drop the files into your preferred order first.
