Online Tools

Every tool on this page is a full implementation, not a demo: open and use, no sign-up, all computation in your browser, and your input never leaves your device. They come from real needs in our daily development and content work — counting words for drafts, formatting JSON while debugging APIs, converting timestamps during incident reviews, generating strong passwords for new accounts. Pick one and try it; improvement ideas are always welcome.

Which tool fits your task

By scenario: writing — the word counter (CJK characters and English words counted separately); APIs and configs — the JSON formatter; cron debugging and log review — the timestamp converter; new accounts — the password generator (live entropy estimate); design and styling — the color converter; slimming images before upload — the image compressor; auth headers and query strings — the encoder; staying focused — the focus timer. Each tool page includes steps and an FAQ; skim it on first use.
