About DevFmt
DevFmt is a collection of developer data tools — formatters, converters, and encoders built for speed and privacy. No accounts, no uploads, no tracking beyond anonymous analytics.
How it works
Every tool on DevFmt runs entirely in your browser. When you paste JSON, CSV, SQL, or any other data into a tool, it's processed locally using JavaScript. Nothing is sent to a server. Nothing is stored. Nothing is logged.
This isn't just a privacy claim — it's an architectural decision. The site has no backend API for data processing. The tools are static pages with client-side logic. You can verify this by checking the network tab in your browser's developer tools.
Why this exists
Developers need formatting and conversion tools daily. Most existing options are slow, cluttered with ads, or send your data to a server. DevFmt is the tool we wanted to exist: fast, clean, private, and keyboard-friendly.
