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.

This page is designed for fast browser-based workflows, so you can move from input to result without installing extra software. Useful for quick API and token workflows. Supports both reversible encoding and one-way hashes. Related tools such as JSON Formatter, Random UUID Generator can help when you need the next step in the same workflow.

How To Use It

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

Most users can finish the task in a few clicks or a quick paste-and-review workflow, which makes this kind of browser tool useful for repeat checks as well as one-off tasks.

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.

Common Use Cases

Useful for quick API and token workflows. This is especially helpful when you want a quick result inside the browser instead of switching between multiple apps or manual cleanup steps. A related follow-up task is often JSON Formatter.
