or click to browse — add as many as you like, nothing leaves your device
Combine multiple PDF files into a single document, in exactly the order you want. Add your files, drag them into position, and download one merged PDF — the entire merge happens in your browser, so your documents are never uploaded to a server.
Frequently asked questions
How do I merge PDF files into one?
Add two or more PDFs, drag them into the order you want them to appear, and click merge. The combined file downloads immediately with all pages in sequence.
Are my PDFs uploaded to a server?
No. Unlike most online PDF tools, the merging is done entirely in your browser using JavaScript — your files never leave your device, which makes it safe for contracts, invoices, medical records and other sensitive documents.
Can I change the order of the files before merging?
Yes. Drag the files into any order before merging — the final PDF follows the arrangement you set, so you can put a cover page first or append attachments at the end.
Is there a limit on file size or number of files?
There is no artificial limit or paywall. Because processing happens on your device, the practical limit is your browser’s memory — typical document-sized PDFs merge in seconds, and even large files usually work fine.
