How norito Works
Every tool runs in your browser. No uploads, no accounts, no artificial limits. Here's exactly how, and why.
Nothing you upload ever leaves your device
Every tool on norito, from merging PDFs to compressing images to formatting JSON, runs entirely inside your browser using JavaScript. When you drop a file into a tool, it's read directly into your browser's memory and processed there. There's no server on the other end receiving it, because there's no upload step at all.
This is possible because modern browsers expose powerful APIs (the File API, Canvas, Web Crypto, and WebAssembly) that used to require server-side processing. norito builds on top of these, plus a couple of well-established open-source libraries for PDF handling (pdf-lib for writing PDFs, pdf.js for rendering them), both of which also run entirely client-side.
No account, no signup, no email
You can use every tool right now without creating an account or handing over an email address. There's nothing to remember, nothing to verify, and nothing tied to your identity.
Works offline once you've visited
norito is a Progressive Web App. After your first visit, a service worker caches the site's core files, so most tools keep working even without an internet connection, and you can install norito to your home screen or desktop like a native app.
How norito makes money
norito is supported by advertising, including some display and interstitial formats, rather than subscriptions or paywalls. There's no premium tier, no feature gate, and no artificial limit designed to push you toward paying. The full details of what data (if any) our ad providers collect are in the Privacy Policy.
What we can and can't see
Because processing happens on your device, we have no way to see the contents of the files you work with, and no server log of them either, there's simply no upload for us to log. Like most websites, we do use standard, privacy-respecting analytics to understand which tools are used and how the site performs, but that's aggregate traffic data, not the contents of your files.
Common questions
Is norito actually free?
Yes, every tool is free with no daily limit, no account, and no watermark. The site is supported by advertising instead of subscriptions.
Do I need to create an account to use norito?
No. Every tool works immediately with no signup, login, or email required.
Does norito work without an internet connection?
Yes, for most tools, once you've loaded norito at least once. It's installable as a Progressive Web App and caches its core files for offline use.
Is there a file size limit?
There's no artificial limit set by norito. In practice, very large files are limited by your device's available memory since everything happens in your browser tab, not by any cap norito imposes.
What happens to my files after I close the tab?
Nothing, because they were never sent anywhere. Once you close or refresh the tab, whatever was in your browser's memory is simply gone.
