Open-sourcing my dev tools as plain HTML files (no npm, no build)

Description and use

Three developer utilities—Base64 encoder/decoder, Unix timestamp converter, and CSS minifier—are now available as standalone HTML files that run entirely in the browser, eliminating server‑side privacy risks and requiring no npm or build steps.

Problem

Free online tools often upload user input to servers, risking privacy and data loss.

Outcome

The utilities run 100% client‑side, eliminating server‑side privacy risks and simplifying deployment.

Workflow

• 1. Open the HTML file in a browser. 2. Enter or paste input into the textarea. 3. Click the Convert button. 4. View the output in the readonly textarea. 5. Close the tab when finished.

Evidence

Each one runs 100% in your browser. No servers, no uploads, no analytics, no tracking.
