Instructions

Software Usage Instructions

Enter hexadecimal numbers

Enter hexadecimal numbers in the text box. Multiple formats are supported, such as FF, 0xFF, and #FF. Multiple numbers can be separated by commas, spaces, or line breaks.

Select the output format

Set the binary output format: space-separated, no separator, line-separated, or comma-separated.

Configure conversion options

Select the bit-length setting (auto/4-bit/8-bit/16-bit/32-bit), uppercase/lowercase mode, and whether to show the 0b prefix.

Batch file processing

You can upload multiple text files containing hexadecimal numbers, with support for batch conversion and downloading the results as a package.

View conversion results

After conversion is complete, you can copy the results, convert them back, or use quick actions for data processing.

FAQ

What is hexadecimal to binary conversion? +

Hexadecimal to binary conversion is the process of converting hexadecimal numbers (base 16, using 0-9 and A-F) into binary numbers (using only 0 and 1). Each hexadecimal digit corresponds to 4 binary bits, which is a common number system conversion in computer science.

Which hexadecimal input formats are supported? +

The tool supports multiple hexadecimal formats: plain hexadecimal (FF), 0x prefix (0xFF), # prefix (#FF), and more. Uppercase and lowercase letters can be mixed, and the tool will automatically recognize and process these formats.

What does bit padding do? +

Bit padding ensures that the output binary number has a fixed length. For example, hexadecimal F converts to binary as 1111, but after 8-bit padding it becomes 00001111. This is useful in programming, especially when handling fixed-length data.

How can I verify the accuracy of the conversion result? +

You can use the reverse conversion function to convert the binary result back to hexadecimal for verification. Also, remember the conversion rule: each hexadecimal digit corresponds to 4 binary digits, such as F=1111 and A=1010, so you can manually verify simple conversions.

What is the difference between uppercase and lowercase modes? +

The case mode affects how hexadecimal letters are displayed: uppercase mode uses A-F uniformly, lowercase mode uses a-f, and keep original mode does not change the case of the input. This mainly affects the display and does not affect the conversion result.

How do I use the quick actions? +

Quick actions provide convenient functions: validate format checks whether the input is valid; clean format removes invalid characters; add/remove prefix manages the 0x identifier; decimal mode converts hexadecimal to decimal for display.

What are the limitations of batch processing? +

The tool supports batch uploading of multiple files, and each file can contain a large number of hexadecimal numbers. Processing is completed locally, and the speed mainly depends on device performance. It is recommended that a single file not exceed 1MB to ensure good processing speed and user experience.

Is my data safe during conversion? +

All conversion operations are completed locally on your device, and data is not uploaded to the server. This ensures that your data remains completely confidential, while also meaning that conversion speed is not affected by the network. You can process sensitive hexadecimal data without worrying about privacy leaks.
