Frequently Asked Questions

Is there any file size limit?

Because processing occurs on your local device, you can merge large document packets (up to 100+ MB) depending on your computer or phone’s memory.

Are my files kept secure?

Yes. Unlike traditional online PDF tools that upload your files to remote servers, Dokuily processes your PDFs entirely inside your browser's private sandbox.
