Handles arbitrary-size integers via BigInt.","longDescription":"Paste a hex number (with or without an 0x prefix) and instantly get its decimal value, plus the binary and octal representations for free. Uses BigInt under the hood so values much larger than JavaScript's Number.MAX_SAFE_INTEGER work fine — useful for inspecting memory addresses, hashes, or large protocol fields. Runs entirely in your browser; nothing leaves your machine.","category":"text","categoryName":"Text & Encoding","keywords":["hex to decimal","hexadecimal to decimal","hex to dec","convert hex to decimal","hex to decimal converter","hexadecimal to decimal online","hex2dec","hex to integer","hex to base 10","0x to decimal","hex to number","hexadecimal converter","hex decimal binary octal"],"badge":"Converter","url":"https://toolsly.tools/hex-to-decimal","inputs":[{"type":"text","key":"hex","label":"Hexadecimal","placeholder":"deadbeef or 0xDEADBEEF","monospace":true,"help":"Optional 0x prefix.
