Trust & Security
A plain explanation of what actually happens to your files and data when you use NexifyTool — not a generic privacy statement, but how the tools are actually built.
Every tool processes files in your browser
All 51 tools on NexifyTool — PDF tools, image tools, calculators, text tools, and generators — are built as client-side code that runs in your browser using JavaScript, WebAssembly, and browser APIs like the HTML canvas. When you upload a PDF or an image, it is read, processed, and turned into your result entirely on your own device. There is no backend endpoint on NexifyTool that a tool sends your file to — the processing engines (including the PDF editing engine and image compression logic) are shipped to your browser and run there.
This is a technical property of how the tools are built, not a promise layered on top of a server-side product — if your browser's dev tools network tab is open while you use a tool, you won't see your file leave your machine.
The few places data does leave your device
We'd rather be specific than make a single blanket claim, so here is every case where something does travel off your device:
- Currency Converter: fetches current exchange rates from a public rates API. No file or personal data is sent — only a request for numeric rates.
- Contact Us form: whatever you type is sent to our support inbox by design, so we can read and reply to it.
- Analytics & advertising: Vercel Analytics, Speed Insights, and Google AdSense run on every page to measure traffic and show ads that keep the tools free — see our Privacy Policy for how those work.
Site-level security
The site is served exclusively over HTTPS. Every response includes a Content-Security-Policy that restricts which scripts and frames are allowed to load, an HTTP Strict-Transport-Security header, X-Frame-Options to prevent the site from being embedded elsewhere, and X-Content-Type-Options to stop browsers from guessing content types in unsafe ways.
Cookies, analytics & advertising
We use Google AdSense to show ads and Vercel Analytics / Speed Insights to understand traffic and performance. These may use cookies as described in our Privacy Policy, which also covers your options for opting out of personalized advertising.
Questions about a specific tool?
Every tool page includes its own privacy note, and this page reflects how the current tools are actually built. If a future tool ever needs server-side processing, we will state that plainly on that tool's page rather than relying on a single site-wide claim.

No. Every tool on NexifyTool — every PDF tool, image tool, calculator, text tool, and generator — runs as client-side code that processes your files and input directly in your browser. There is no file-upload API on the backend for any tool to send data to.
