Quick summary
Learn what client-side processing means, what remains on your device, and how to use browser tools responsibly with business data. This guide gives you a clear, practical explanation before you use the related online tool.
Meaning of client-side
Client-side means the main transformation or calculation runs in JavaScript or WebAssembly inside the browser rather than on the application server.
Benefits
It can reduce file transfer, avoid server storage, provide immediate interaction and make many tools usable without accounts.
Network resources
A client-side tool may still download code, fonts, libraries or language models. This is different from uploading the user's document, but should be disclosed clearly.
Browser memory and downloads
Input and results remain available to the active page while it is open. Downloaded files persist on the device until the user manages them.
Analytics boundaries
Responsible tools should not inspect or send document contents through analytics. Users should still review the privacy policy and organisation controls.
Responsible usage
Avoid shared devices for confidential work, keep browsers updated, review extensions and follow internal policy for regulated information.

Does client-side mean offline?
Not necessarily. The page or processing models may need internet access even though the document is not uploaded.
Are downloaded results automatically deleted?
No. The user must manage downloaded files.
Can browser extensions see page data?
Extensions with broad permissions may access page content, which is why managed browsers are preferable for sensitive work.
Is client-side suitable for every confidential file?
No. Organisational classification and policy determine what is permitted.
