Merge PDFs
Combine multiple PDF files into a single document — entirely in your browser. Drag, drop, reorder, and merge as many PDFs as your device can handle. No upload, no signup, and no file ever sent to a server.
How to merge PDFs
- Drop your PDFs into the box above (or click to choose them).
- Drag the file thumbnails to set the order you want.
- Click Merge — the combined PDF downloads instantly.
- Done. Nothing was uploaded; nothing was stored.
Why merge PDFs with QuickPDFKit?
- 100% private — files are processed by your browser, not a server.
- No upload — works even if you're offline after the page loads.
- No file count limit — only your device's memory caps it.
- No watermark, no signup, no email — just merge and download.
- Quality preserved — the original PDFs are copied byte-for-byte.

Frequently asked questions
Is there a file size limit?
No fixed cap — the limit is whatever your browser's memory allows. On a modern laptop, hundreds of megabytes is typical.
Are my files uploaded anywhere?
No. We use the open-source pdf-lib library which runs entirely in your browser. You can verify this by disconnecting from the internet after the page loads — merging will still work.
Can I reorder individual pages, not just files?
For now, this tool merges whole files. To reorder pages within a PDF, use Split PDF first, then merge the pieces back in the order you want.
Will the merged PDF be larger than the originals combined?
Slightly larger — there's a small overhead from merging metadata. To shrink the result, run it through Compress PDF.
