Are my PDFs uploaded to a server?

No. Merging runs entirely in your browser using pdf-lib and PDF.js. Your files stay on your device.

Can I change the order of PDFs before merging?

Yes. Drag files in the list or use the up and down arrows to set the final page order.

Combine multiple PDFs into one file - reorder pages, merge instantly, download when ready.

🔒 Files never leave your browser

PDF only Max 50 MB each Up to 25 files

Your queue is empty - add two or more PDFs to merge, or one file to re-save.

Optional compression while merging

Compress images when merging (smaller file, slower)

Combine admit cards, certificates, and proofs into one upload. Drag files to set order - the top file’s pages appear first in the merged PDF.

Password-protected PDFs?

Protected PDF? Unlock PDF first, then merge here.

When should I use compression?

Turn on compression for phone scans and large image PDFs. For text forms, leave it off for faster merge and sharper text.
