FAQ
Does this tool support large numbers beyond JavaScript 64-bit float limit?
Yes. The conversion engine uses arbitrary-precision BigInts so you can convert 128-bit, 256-bit, or arbitrarily large integers without precision loss.
Can I convert text into Hex and Binary?
Yes. Switch the Input Type to 'Text String to ASCII/Hex/Bin' to convert every character into its hexadecimal, binary, and ASCII codes.
