FAQ
- Is my data sent to a server?
- No. Everything happens in your browser, so it's safe to use with private data.

- It removes all spaces and line breaks, making the JSON as small as possible.
- How big can the JSON be?
- Several megabytes work fine. Very large files depend on your device's memory.
