Why browser-based?

Privacy: No file ever leaves your device. Unlike cloud-based tools, privotools processes everything locally in your browser — no server receives your data, no third party can access your files, and nothing is stored or logged.

Speed: Because processing happens on your own hardware, there is no upload wait and no round-trip to a remote server. Results appear almost instantly, even for large files.

Offline-capable: Once the page has loaded, most tools continue to work even if your internet connection drops. There is no dependency on an external API or backend service.

About privotools

Most online tools have a dirty secret: when you "upload" a file to compress it, convert it, or edit it, that file travels across the internet, lands on a stranger's server, gets processed by someone else's computer, and may linger in a database long after you've closed the tab. You handed over your photos, your documents, your data — to a service you know nothing about — just to get a simple task done.

privotools was built around one idea: that should never be necessary.

Every tool on this site runs entirely inside your web browser. Your files are processed by your own device's CPU. Nothing is ever transmitted to any server. There is no upload. There is no cloud. There is just your browser, doing the work locally, the way it always could have.

How It Works

When you use a tool on privotools, your browser downloads a small piece of JavaScript code — the tool itself. From that point on, everything happens on your machine. Your files are read directly from your local storage into browser memory. Processing happens using your own CPU. The result is written back to your device. At no point does any data leave your computer.

This is possible because modern browsers are remarkably capable. APIs like the File API, Canvas API, and WebAssembly allow complex tasks — image compression, text analysis, file conversion — to run entirely client-side, with no server involved whatsoever.

Our Privacy Commitment

We make these commitments unconditionally:

No server ever receives your files. Our infrastructure serves only the HTML, CSS, and JavaScript that makes up the tool. Your actual files — images, documents, text — never leave your device.

No data is stored or logged. We have no database of user files. We have no file processing logs. There is nothing to subpoena, nothing to breach, nothing to sell.

No account is required. You do not need to sign up, log in, or provide an email address to use any tool on this site.

No tracking of file contents. The only analytics we use are aggregate, anonymous page view counts — we know a page was visited, not by whom or with what files.
