100% Private — Files Never Leave Your Device

All processing happens locally in your browser using WebAssembly. Your files are never uploaded to any server and never used to train AI models.

How to Use This Tool

  1. Upload your first PDF (e.g. odd pages scan).
  2. Upload your second PDF (e.g. even pages scan).
  3. Choose the interleave order (1,1,2,1,3,1 or alternating).
  4. Click "Mix PDFs" and download the combined document.

Why Choose LovePDFs?

Fix double-sided scans

Combine separately scanned front and back sides of a document into the correct page order.

Flexible interleaving

Choose from different alternating patterns to match your specific document structure.

Browser-based privacy

Both uploaded PDFs are processed locally — no server sees your documents.

Why LovePDFs — The Private Adobe Alternative

LovePDFs is a completely free alternative to Adobe Acrobat, Smallpdf, and ilovepdf. Unlike other online tools that upload your files to remote servers, LovePDFs processes everything in your browser using WebAssembly technology. Your files never leave your device — not even for a second.

This makes LovePDFs the right choice for sensitive documents — contracts, medical records, financial files, government forms, and anything you wouldn't want sent to a third-party server. It's also the only major PDF tool suite that is GDPR-friendly by design, since no personal data or file content ever leaves your browser.
