Loading tool runtime...

What it does

Base64 Encode/Decode is handy when you need to inspect or transform encoded strings without dropping into a terminal or writing a quick script.

Data stays local

Open Base64 Encode/Decode and enter the source input you want to work with.
Run the tool once with a small sample so you can confirm the result format.
Copy, download, or reuse the output in your target app after a quick verification pass.

Encode text for transport or quick test payload generation.

Decode base64 snippets while debugging APIs, email payloads, or auth data.

Inspect small encoded files or attachments during troubleshooting.

Is base64 encryption?

No. Base64 is an encoding format, not a security mechanism.

Can I decode binary content too?

Yes, but practical browser handling still depends on file size and the output workflow.

Base64 Encode/Decode is designed to run in the browser. Review outputs before sharing them with any external service or workflow.
