How it works
This tool joins multiple PDF documents into one file, keeping the page order you set. Drop your files onto the page (or tap to pick them on a phone), drag them into the right sequence, and click Merge — the combined PDF downloads instantly to your device. Each file shows its size and page count, so you can double-check you grabbed the right versions before combining them. There is no step where anything gets sent anywhere: the moment your files are selected, they are read directly into your browser's memory and stitched together right there.
Unlike most online PDF mergers, this one does not upload your documents to a server. The merging is done by JavaScript running in your own browser, which means there is no file size cap imposed by an upload, no waiting in a processing queue, no watermark stamped on the result, and no account required. It is also faster for large files: a 100 MB scan that would take minutes to upload on a slow connection merges in seconds because the bytes never travel over the network. You can verify this yourself — open your browser's developer tools, watch the network tab, and merge a file: no upload request appears.
That makes it safe for exactly the documents people most often need to merge: contracts, invoices, bank statements, medical records, ID scans, and university applications. Nothing is stored, cached, or logged anywhere, because nothing ever reaches us. Close the tab and every trace of your document is gone. Typical uses include combining scanned chapters into one readable file, assembling several invoices into a single attachment for accounting, or packaging a cover letter and CV into one PDF for a job application.
Frequently asked questions
Is there a limit on file size or number of files?
No hard limit. Because files are processed on your device, the only practical limit is your computer's memory. Merging dozens of typical PDFs works fine.
Are my PDFs uploaded to your server?
No. The entire merge runs inside your browser using JavaScript — the network is only used to load the page itself, never to move your files. You can confirm this in your browser's developer tools: no upload request ever appears.
Will the merged PDF have a watermark?
Never. The output is a clean PDF containing exactly the pages of your input files, in the order you arranged them.
