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.
