Negative numbers are allowed (sign-magnitude form). Hex is case-insensitive on input; output uses lowercase. Whole numbers only — fractional binary not supported.

Decimal ↔ binary ↔ octal ↔ hex. Edits in any field flow to the other three live. Per-base validation so non-binary digits in the binary field don’t silently coerce. Negative numbers supported.

Nasıl Kullanılır

Type a number in any of the four fields.
The other three convert instantly.
Invalid characters for that base are silently rejected.

Sık Sorulan Sorular

What's the largest number supported?

JavaScript's parseInt is reliable up to about 2^53 in decimal — beyond that, integer precision is lost. For most practical needs (file sizes, color codes, IPs) this is far more than enough.

Is hex case-sensitive?

Input accepts both — '2A' and '2a' both parse to 42. Output uses lowercase by convention (matches CSS hex colors).
