Hex to Binary Converter: Convert Hex Values Online
The Hex to Binary Converter turns a hexadecimal value into its binary equivalent: every hex digit becomes four bits, so ff becomes 11111111. Paste a value, optionally include the 0x prefix, and choose 4-bit or 8-bit grouping to make the result easier to read. Copy the binary output for code, documentation, or another tool. Conversion runs privately in your browser.
The Hex to Binary Converter changes a hexadecimal value into its binary equivalent. Paste a hex value to get a binary result that you can copy into code, documentation, a ticket, or another tool. For example, the hexadecimal value ff converts to 11111111.
The conversion follows a direct mapping: each hexadecimal digit becomes four binary bits. You can optionally include the 0x prefix and choose whether the output is grouped in sets of 4 or 8 bits. These grouping options change how the binary result is displayed, while each hex digit still represents four bits.
Hexadecimal is a base-16 number system, while binary uses base 2. Developers often use hexadecimal as a compact way to write values and binary when they need to inspect or provide the individual bits. Converting between them helps when a system expects one format, or when you need to compare a binary value with its hexadecimal representation.
The conversion runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. There is no signup, and the converter works offline once the page has loaded.
This tool is useful for developers and DevOps engineers who need a quick way to convert, check, or share hexadecimal and binary values. The optional prefix and grouping settings make it easier to prepare the output for the context where you need to use it.
Step 1: Paste a hexadecimal value into the input. You can use the example ff or enter your own hex value.
Step 2: Choose whether to include the optional 0x prefix in your input. The prefix is not a hexadecimal digit.
Step 3: Adjust the digit grouping option if needed. The result can be grouped in sets of 4 or 8 bits.
Step 4: Review the binary result. Each hexadecimal digit corresponds to four binary bits.
Step 5: Copy the binary output for use in code, documentation, a ticket, or another tool.
Use case: Convert hexadecimal data for a system or workflow that accepts only binary values.
Use case: Check whether a binary value you received matches its hexadecimal original by comparing their conversions.
Use case: Prepare a hexadecimal snippet as binary for documentation, a ticket, or a commit message.
Use case: Sanity-check a hex-to-binary conversion before adding the result to code.
Use case: Inspect a hexadecimal value in binary when you need to reason about its individual bits.
Use case: Choose 4-bit or 8-bit grouping to make a binary value easier to scan while discussing it with teammates.
