Why Tuko is the Best PDF Merger for Privacy

Most online PDF tools require you to upload your sensitive documents to their servers. This poses a significant privacy risk, especially for legal or financial documents.

Tuko is different. Our tool uses advanced WebAssembly technology to perform the merging process directly in your browser. This means:

Zero Uploads: Your files never leave your computer.
Offline Support: Once the page is loaded, you can merge PDFs without an internet connection.
No Limits: Merge as many files as you want, regardless of size.
