Base Converter (2-64)

Supports real-time conversion across bases 2 to 64, defaulting from base 10 to base 16 without page reload on base changes.

You can type on either side for two-way conversion and copy either result with one click.

  1. Select left and right bases (2-64).
  2. Type a number on either side and the other side updates instantly.
  3. When you change bases, the URL updates to an independent route (for example, base2-to-base16) without reloading the page.
  4. Click Copy to copy the converted result quickly.

Which characters are supported?

The 64-base alphabet is 0-9, A-Z, a-z, +, /. For smaller bases, only characters inside that base range are valid.

Can I type on the right for reverse conversion?

Yes. Both sides are editable and conversion follows the side you are currently typing in.

Why do I get an invalid format message?

That usually means at least one character is not valid for the current base, such as using letters beyond F in base 16 or digits 2-9 in base 2.
