Encoding tool

String Encoder and Hasher

Encode, decode, and hash strings without leaving the browser.

What This Tool Does

This encoder tool combines the common string operations developers and power users need most: Base64 encode, Base64 decode, and SHA hashing. It is faster than switching across several tiny utilities and keeps the workflow in one page.

How To Use It

  1. Paste or type your string.
  2. Choose Base64 encode, Base64 decode, or a hash mode.
  3. Copy the generated output from the result panel.

Why Use This Tool

  • Useful for quick API and token workflows.
  • Supports both reversible encoding and one-way hashes.
  • Runs directly in the browser with no backend dependency.

FAQ

Which hashes are included?

This version supports SHA-1, SHA-256, and SHA-512 through the browser crypto API.

Can it decode invalid Base64?

If the input is not valid Base64, the tool shows an error instead of output.

Is hashing the same as encryption?

No. Hashes are one-way digests, while Base64 is only an encoding format.
