linu-li

A bunch of browser-based tools for everyday stuff — PDF editing, image processing, dev utilities, etc. Everything runs locally in your browser, no uploads, no tracking.

Live: linu.li

Why

Most online tools for things like PDF merging or image compression work by uploading your files to some server. I didn't really want that, so this is all client-side — WebAssembly and vanilla JS, nothing leaves your machine.

No analytics, no ads, no cookies. Also works offline as a PWA.

Stack

Plain HTML, CSS, JS. No build step, no bundler, no framework. Just open it.

Libraries used:

• pdf-lib, pdf.js, jspdf — PDF stuff
• cropperjs, piexifjs — image handling
• dayjs — dates
• marked — Markdown parsing
• sql-formatter, json5, jsdiff — text/code tools
• Web Crypto API + crypto-js — hashing/crypto

Running locally

Needs to be served over HTTP (ES modules + service worker don't work on file://).

git clone https://github.com/immineal/linu-li.git
cd linu-li

# python
python -m http.server 8000

# or node
npx serve .

Then open http://localhost:8000.

Deployment

GitHub Actions deploys to All-Inkl via FTP on every push to main. Config is in .github/workflows/deploy.yml.

If you want to use your own server: add an FTP_PASSWORD secret in the repo settings and update the server/username fields in the workflow file.
