Hex Converter
Convert between hexadecimal and text, decimal or binary formats.
Convert hex values to readable text, decimal numbers or binary - and back again. If you're staring at a hex dump and need to make sense of it, this tool does the decoding for you. Works both ways, so you can also encode regular text into hexadecimal.
How Hex-to-Text Conversion Works
Every character has a numeric code in ASCII or Unicode. The letter "A" is 65 in decimal, which is 41 in hex. When someone sends you a hex string like 48 65 6C 6C 6F, that's the word "Hello" encoded as hex byte values. This converter reads those values and turns them back into text you can actually read.
When You'd Actually Need This
- Reading hex dumps from debuggers or crash logs
- Analyzing network packet captures in Wireshark
- Working with binary file headers and magic numbers
- Decoding hex-encoded data in CTF competitions
- Converting CSS color codes like #FF5733 to RGB values
- Inspecting cryptographic hashes and checksums
Hex vs. Binary vs. Decimal
These are all just different ways to write the same number. Decimal 255 equals hex FF equals binary 11111111. Hex is popular because it's compact - two characters per byte instead of eight in binary. That makes memory dumps and large data sets way easier to scan through.
Getting Gibberish? Here's Why
If your converted text looks like random symbols, the original data probably wasn't text at all. Binary files like images or executables contain raw byte data, not encoded words. Also check your encoding - UTF-8 and ASCII handle characters differently above the 127 range. Make sure the hex string only contains valid characters (0-9 and A-F).
How to Use
- Paste your hex string or plain text into the input box.
- Pick the conversion direction (hex to text or text to hex).
- See your converted result instantly.
- Copy the output with one click.
Frequently Asked Questions
How do I use the Hex Converter?
Enter hex, text, decimal or binary depending on the mode. The tool converts it to the other formats. Check that the input is in the right mode before trusting the output.
What characters are valid in hex?
Hex uses 0 to 9 and A to F. Uppercase and lowercase both work. Any other character usually means the value is not valid hex.
Why does hex-to-text look unreadable?
The hex may represent binary data, not text. Images, compressed data and encrypted values will not read like sentences. If the output looks strange, the input may not be a text string.
How does hex work in CSS colors?
Six digit HEX colors use two digits each for red, green and blue. `#FF0000` is full red. Eight digit HEX can also include transparency.
Can I convert large hex numbers?
Yes, but very large numbers may exceed what some programming languages handle safely. If precision matters, use a tool or language that supports big integers.
