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

  1. Drop your PDFs into the box above (or click to choose them).
  2. Drag the file thumbnails to set the order you want.
  3. Click Merge — the combined PDF downloads instantly.
  4. 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.

Common uses

  • Combining a multi-part contract into one signable file

  • Joining e-book chapters into a single reader-friendly file
  • Assembling a submission packet (cover letter + CV + portfolio)
  • Consolidating receipts for an expense report
  • Stitching a multi-page invoice that came as separate scans

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.
