Do I need to create an account to use privotools?

No account, registration, or email address is required. You can use any tool on privotools immediately, with no login.

What tools does privotools offer?

privotools currently offers four tools: PixLite (image compressor), WordLens (word counter and text analyzer), KeyForge (password generator using the Web Crypto API), and DevKit (seven developer utilities including JSON Formatter, Base64 Encoder/Decoder, Hash Generator, URL Encoder/Decoder, JWT Decoder, Timestamp Converter, and Regex Tester). All tools are 100% browser-based. A Code Formatter, Diff Checker, PDF Tools, and Finance Calculator are in development.

Is it safe to use privotools with sensitive or confidential files?

Yes. Because your files never leave your device, there is no risk of data interception, server-side breaches, or third-party access to your file contents. There is no server infrastructure that could receive or store your files.

Yes. privotools is fully responsive and works on smartphones and tablets. All tools run in mobile browsers including Chrome for Android and Safari for iOS. Processing speed depends on your device hardware, but modern phones handle typical files quickly.

Powerful tools. Your files never leave your device.

Q: Does privotools work offline?

Partially. An internet connection is needed to initially load the page and scripts. Once loaded, most tools continue to work even if your connection drops, because all processing happens locally on your device with no server dependency.

Q: What browsers does privotools support?

privotools works in any modern browser with JavaScript enabled, including Chrome, Firefox, Safari, and Edge. No plugins, extensions, or software installation are required.

Q: How is privotools different from tools like TinyPNG or WordCounter.net?

Most online tools process your files on their servers — your image or text travels across the internet, is processed on a third-party machine, and may be retained in logs or databases. privotools processes everything inside your own browser. Your files never leave your device, so there is nothing to intercept, breach, or retain.

Q: Does privotools collect any personal data?

privotools does not collect, store, or transmit your files or file contents. The only data collected is anonymous, aggregate page-view analytics used to understand which tools are most popular. No personal data is attached to these analytics.

privotools is a collection of 100% browser-based utilities built for privacy. Your documents, images, and text stay on your device at all times with no uploads and no servers.

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.

No account required: You do not need to sign up, verify an email, or hand over any personal information. Open the tool, use it, done.

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.

Who uses privotools?

Browser-based privacy tools are useful any time you need to get something done quickly, without handing over your files to a service you don't know.

📸 Bloggers & Content Creators

Compressing images before uploading to a CMS is one of the single biggest wins for page speed. PixLite lets you shrink a batch of photos in seconds — without sending them to a third-party server — and download them ready for web use.

✍️ Writers & Students

WordLens gives instant word counts, character counts, and readability scores for essays, articles, and assignments. Writers working within submission limits or SEO targets can check their progress without pasting sensitive drafts into an external service.

💻 Developers & Designers

Frontend developers and UI designers regularly need to optimize images for web delivery. Running compression locally means no file size restrictions, no waiting for uploads, and no risk of proprietary mockups or unreleased assets touching a third-party server.

🏢 Small Business Owners

Managing a website without a dedicated developer means handling image optimization yourself. privotools gives small business owners professional-grade tools — image compression, text analysis — with no subscription and no technical setup required.

🔐 Privacy-Conscious Users

Some files are simply too sensitive to run through an unknown cloud service — legal documents, medical records, financial spreadsheets, personal photos. Browser-based processing means those files never leave your machine, no exceptions.

📱 On-the-Go Users

Need to compress a photo on your phone before sending it? WordLens and PixLite work fully on mobile browsers. No app installation required — open the tool, do the work, move on.
