Frequently Asked Questions
Is my code/data safe when using these tools?
Yes. All formatting, encoding, and conversion happens client-side in your browser. Your code and data never leave your device.
Why would I need to format JSON?
Formatted (pretty-printed) JSON is easier to read, debug and share with team members. Minified JSON is smaller for production use in APIs and config files.
What is Base64 encoding used for?
Base64 is used to encode binary data (images, files) as ASCII text so it can be safely transmitted in JSON, email or HTML attributes without corruption.
How does URL encoding work?
URL encoding replaces special characters (spaces, &, =, etc.) with % followed by their hexadecimal code (e.g. space becomes %20) so they can be safely included in URLs.
What is the difference between binary, octal, decimal and hexadecimal?
These are different number bases: binary (base 2, digits 0-1), octal (base 8, digits 0-7), decimal (base 10, digits 0-9), hexadecimal (base 16, digits 0-F). They all represent the same values differently.
