Frequently Asked Questions
- What does minification do?
- Minification removes all insignificant whitespace (spaces, tabs, newlines) from JSON while preserving the data structure and string values.
- Is whitespace inside strings preserved?
- Yes. Only whitespace between tokens is removed. Whitespace inside string values is never modified.
- How is the byte size calculated?
- We use the TextEncoder API to calculate actual UTF-8 byte size, which is more accurate than character count for strings containing non-ASCII characters.
- Is my data sent anywhere?
- No. All processing happens locally in your browser. Your data never leaves your device.
