Frequently Asked Questions.
Everything you need to know about OpenFormatter's security protocols, supported schemas, and integration patterns.
Data Security & Privacy
Is my code or data stored on your servers?expand_more
No. OpenFormatter operates on a strictly stateless architecture. Any data you paste into the editor is processed in-memory and never written to a database or disk. Once you close your browser tab or refresh, all input data is purged from memory.
Does the formatting happen client-side or server-side?expand_more
Whenever possible, OpenFormatter prioritizes WebAssembly (WASM) to perform formatting directly in your browser. This ensures that sensitive data never leaves your machine. Only complex transformations (like SQL prettifying for specific dialects) are processed via our secure, encrypted gateway.

Local History
We store your last 10 transformations in localStorage for quick recovery, encrypted with a session key.
Can I customize the indentation depth?expand_more
Yes. Each tool has an options panel where you can adjust spacing (2, 4, or 8 spaces), choose between tabs and spaces, and toggle quote styles (single vs. double).
Is there a file size limit?expand_more
OpenFormatter is optimized for large files up to 50MB. For files over 10MB, we recommend using the upload button rather than paste for better performance.
Does OpenFormatter support dark mode?expand_more
Yes. You can toggle dark mode using the theme button in the top navigation bar. Your preference is saved to localStorage.

Is OpenFormatter open source?expand_more
The core formatting engine is open source on GitHub. The web application and API infrastructure are proprietary.
