DOTi is ready
Add at least two PDFs. I’ll help keep the final order obvious.
Encrypted, damaged, or permission-restricted PDFs may need to be unlocked or repaired before they can be merged.
Merge PDFs without sending them away
Applications, contracts, receipts, scans, and supporting documents often arrive as separate PDFs. This tool lets you combine them into one ordered file directly in the browser.
Your originals stay intact
Ninjitzu creates a new PDF. The selected source documents are not edited or overwritten.

Quick answers before you combine your files.
Are my PDFs uploaded?
No. The selected PDFs are combined in your browser using local processing.
Can I change the order before merging?
Yes. Use the up and down controls to set the final document order before creating the merged PDF.
Will the original PDFs be changed?
No. Ninjitzu creates a new merged PDF and leaves the originals untouched.
Can I merge password-protected PDFs?
Encrypted or restricted PDFs may not be readable until they are legitimately unlocked first.
