How it works

3 steps, no account. It runs in your browser and nothing is uploaded.

  1. Enter text or a file

    Type or paste anything, or drop a file onto the input; the Base36 updates with every keystroke.

  2. Choose the form

    Lowercase or uppercase: pick in the bar and the result is rewritten in place.

  3. Copy, download or swap

    Copy the Base36, download it as a text file, or press Swap to decode it back.

Where Base36 is used

Alphanumeric and case-insensitive: the alphabet of short ids and `toString(36)`. Where Base36 does its work.

  • JavaScript numbers

    `(123456789).toString(36)` is `21i3v9`, and `parseInt("21i3v9", 36)` brings it back: Base36 is built into the language.

  • URL shorteners

    A shortener turns the row id of a link into a few Base36 characters: the slug in `example.com/2x9ka`.

  • Reddit ids

    Reddit's `t3_1a2b3c` ids are Base36 counters behind a type prefix.

  • Licence and tracking codes

    A code that will be typed from paper or read over the phone wants letters and digits that case can't break.

  • Everywhere numbers are

    Ruby's `Integer#to_s(36)`, Python's `int(s, 36)`, PostgreSQL extensions: most stacks convert without a library.

  • Short keys

    A hash's first bytes as Base36 make a short, case-insensitive cache key or file name.
