The toolkit
Four tools. One tab.
Each utility does one job well—no dashboards, no account walls, no data pipeline behind the curtain.
Timestamp Converter
Translate Unix time in seconds or milliseconds into readable dates—across any timezone.
Open toolBase64 Encoder / Decoder
UTF-8 safe Base64 conversion with a URL-safe mode and live validation.
Open toolImage ↔ Base64
Convert images to data URIs or restore Base64 text files—without sending files to a server.
Open toolPixel Scramble
Password-shuffle every pixel, then restore it later. Salt is embedded in the PNG.
Open toolWhy local-first
Minimal by design. Private by architecture.
Privacy is not a setting here. It is the only way the application knows how to work.
Local by construction
Files are read with FileReader, images are decoded on a canvas, and keys are derived with Web Crypto. There is no upload endpoint to forget to secure.
Fast, because it is simple
Static pages, a local font, no video, no chat widget, and no third-party scripts. Open a tool and it is ready to work.
Built on web standards
Semantic HTML, keyboard navigation, visible focus states, reduced-motion support, and sensible titles on every route.
Nothing to install
Close the tab when you’re done.
There is no account to delete and no file to clean up. Your browser is the entire application.
