Engineering Breakdown

NEXUS-70 is a static, multi-page web application deployed on a CDN with no backend. Each sub-page is a self-contained hub that shares one cyberpunk design system and three small engines: an audio engine (decoding, an in-house radix-2 FFT, spectrogram rendering, WAV encoding, HRTF spatial panning and noise synthesis), a canvas engine (cover-fit scaling, binary-search size compression, flood-fill background keying, a GIF89a LZW encoder) and an app shell (global search index, quick launcher, modal manager). Heavy document work is delegated to pdf-lib, jsPDF and JSZip loaded from a CDN on only the pages that need them. Because every operation happens on your own device, files are never transmitted, there is nothing to breach, and the suite keeps working when your connection drops after the first load.

How to use it in 3 steps

Search the directory, press Ctrl + K, or open one of the six tool hubs.
Drop your file — audio, photo, PDF or video. It is read straight into browser memory.
Adjust the settings, then download the finished PDF, image, audio or text result.

Frequently asked questions

Is NEXUS-70 really free and private?

Yes. Every tool runs inside your browser, so your files are never uploaded to a server. There is no account, no watermark and no usage limit.

Does it work offline?

After the first load the shell and image / audio tools work without a connection. PDF and ZIP features need their CDN libraries to be cached by your browser or to be fetched once.

Which browsers are supported?

Current Chrome, Edge, Firefox and Safari on desktop and mobile. Web Crypto requires HTTPS or localhost.

How many tools are included?

Seventy, grouped into six hubs: Audio Lab, Passport Studio, Media Forge, PDF Vault, Cyber FX and Dev Core. Use the global search to find any of them.

How can I deploy my own copy?

The project is plain static files. Upload the folder to Cloudflare Pages, Netlify, GitHub Pages or any static host — no build step is required.
