How it works

Here's exactly what happens when you use a Ghivo tool — no surprises.

01

Paste, type, or drop a file

Your data goes straight into the tool on your screen. Nothing is sent anywhere.

02

Your browser does the work

Everything runs locally — even large files are processed in a background thread so the page stays fast.

03

Copy or download the result

Done. Your data never left your device and nothing was stored on any server.

Your files stay private

Nothing is uploaded. Everything runs in your browser tab — images, text, passwords, all of it.

Instant, no waiting

No servers to round-trip. Results appear immediately, even on large files.

Works without internet

Install it once and every tool works offline. Great on planes, trains, or spotty connections.
