Free PDF Merger
Join multiple PDFs locally in your browser, in exactly the order you choose. No account, upload, or server-side processing required.
Private by default: your PDF bytes, names, contents, and generated output remain in browser memory and are never sent to QuickKit servers.
Merge stays disabled until at least two valid PDFs are ready. Your files are never uploaded or stored by QuickKit.
A clear four-step flow

Before you start
Questions, answered.
Are my PDFs uploaded?
No. PDF bytes, file names, page contents, and the generated file stay in your browser memory. QuickKit does not send them to its servers.
Does merging reduce PDF quality?
No. QuickKit copies the original PDF pages into a new document rather than rasterizing them, so selectable text and page content are preserved where the source supports them.
Can I change the order?
Yes. Use the Move Up and Move Down buttons beside each file before you merge. The list order is the output order.
How many PDFs can I merge?
The browser-safe limits are 20 PDFs, 10 MiB per file, 30 MiB combined, and 500 total pages per merge. These limits help keep mobile browsers responsive.
