Resistor Color Code & SMD Decoder
Decode 4–6 band resistor colors, reverse values into bands, and read SMD markings locally.
About this tool
Calculate resistor values from color bands, convert values back to colors, and decode SMD and EIA-96 markings in your browser. Resistor Color Code & SMD Decoder runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Resistor Color Code & SMD Decoder is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
