Free, privacy-first online tools that run entirely in your browser. Image, PDF, text, encoding, color and developer utilities — files are processed locally on your device and never uploaded to a server.
Lizely began with a small annoyance: most "free online tools" make you upload a file to a stranger's server just to resize an image or merge two PDFs. That trade felt unnecessary for work a browser can already do on its own.
So every tool here runs locally — your files never leave your device, and most tools need no account. It's a solo project, and the toolbox grows whenever an everyday task turns out to be more annoying than it should be.
We also publish guides on the workflows behind the tools: what actually changes when you compress an image, when format choice matters, and where the usual shortcuts break down.
Our stack
Next.js (App Router) with React and TypeScript, styled with Tailwind CSS. Content and tool metadata live in SQLite via Drizzle ORM, rendered with incremental static regeneration.
The tools themselves are client-side: Canvas and the File APIs handle most image and text work, with WebAssembly where a task needs real codec or PDF processing. Nothing is sent to a server, which keeps the tools fast and the hosting boring.
Runs on a single small VPS behind Cloudflare, with PM2 keeping the Node process and a Python worker alive.
