Our Mission
Developer tooling shouldn't be behind a login wall. We believe that the utilities every developer reaches for daily — formatters, encoders, decoders, generators — should be freely available, fast, and respect your privacy.
FormatCraft was created to be the go-to bookmark for developers who want clean, distraction-free tools without the noise. No accounts, no ads, no cluttered UI. Just the tool, and the result.
Instant & Fast
The tools process your input in your browser, so results are instant and there is no server round-trip.
Privacy First
What you paste into the tools is not uploaded or stored. The exception is Private Notes, which stores an end-to-end encrypted copy we cannot read.
Always Free
Every tool on FormatCraft is free to use, forever. No sign-up, no paywall, no premium tier.
Developer Focused
Built by developers for developers. We focus on the tools you actually need in your daily workflow.
Built by developers, for developers
FormatCraft is a passion project built to solve the small frustrations of daily development. Every tool was born out of a real need — something we wished existed without jumping through hoops to access.
