TOOLS — SMALL, SHARP, FREE
Utilities that respect your time.
Four small instruments for everyday engineering work. Every tool runs entirely in your browser — no upload, no account, no telemetry. Open one, do the thing, close the tab.
Password Generator
Cryptographically random passwords, 8–64 characters, with per-class control and an honest strength readout.
02 / VALIDATEJSON Formatter
Paste, pretty-print, minify. Parse errors are pinned to the exact line and column, not a vague shrug.
03 / ENCODEBase64 & URL
Encode and decode Base64 or URL strings, UTF-8 safe. Umlauts and emoji survive the round trip.
04 / DIGESTHash Generator
SHA-1, SHA-256, SHA-384 and SHA-512 over text or files, computed locally with WebCrypto.
Why these tools exist
Most online utilities ship your input to a server you know nothing about. These don't. Everything on this site is plain HTML, CSS and JavaScript executing on your machine — the network tab stays quiet after the page loads.
TechLink Tools is a side project of TechLink. If you need to hand a secret to a colleague, TechLink Vault destroys it after a single read; for moving files, there's TechLink Files.
