🔄 Converters

What are Converters?

Things that are the same value written differently. Turning a designer's HEX into RGB, reading hex as binary, exporting JSON as a CSV your spreadsheet will actually open — conversions you need often but look up every single time.

When you need them

• A HEX color from a mockup needs to go into CSS as RGB or HSL
• You need to open JSON data in a spreadsheet without mangling it
• You're moving between hex and binary to check bit values
• You need file sizes converted exactly (MB vs MiB)
